Primary Disseminated Peritoneal Hydatidosis: A Rare Presentation of Common Infectious Disease

Introduction: Human hydatidosis, being caused by the larvae of Echinococcus granulosus, rarely presents as disseminated peritoneal disease which can be either primary or secondary. Iatrogenic secondary peritoneal echinococcosis is more common while primary form of infection is found occasionally. Radiological imaging including ultrasonography or computed tomography (CT) scan is considered the most essential diagnostic modality. The mainstay of treatment for localized hydatid cysts or infected cysts and multiple septations is the surgical management in the form of excision. Disseminated hydatid disease presents with varied manifestations involving multiple organs. However, primary peritoneal hydatidosis is being rare entity, accounting for only 2% of cases of abdominal hydatidosis. The dissemination to multiple organs usually occurs through either lymphatic or systemic circulation. Case Report: In this case report, we present an uncommon presentation of primary disseminated peritoneal hydatidosis. On further evaluation, the patient was diagnosed to have peritoneal hydatidosis with hepatic and lung hydatid cyst involvement on contrast-enhanced CT abdomen. The patient was managed conservatively with oral tablet albendazole 400 mg twice a day during his 1st admission and later presented again with acute abdomen, and then, radical surgery in the form of pericystectomy was carried out but patient developed large gastric perforation, for which again surgery was attempted, but patient succumbed to his illness. In this case, the rare presentation of primary disseminated peritoneal hydatidosis as acute abdomen was observed. Conclusion: Primary disseminated peritoneal hydatidosis as the presentation of acute pain abdomen is rare entity. This case emphasizes an atypical presentation of hydatidosis.

Untargeted metabolomics to discriminate liver and lung hydatid cysts: Importance of metabolites involved in the immune response

The Echinococcus granulosus sensu lato species complex is responsible for the neglected zoonotic disease known as cystic echinococcosis (CE). Humans and livestock are infected via fecal-oral transmission. CE remains prevalent in Western China, Central Asia, South America, Eastern Africa, and the Mediterranean. Approximately one million individuals worldwide are affected, influencing veterinary and public health, as well as social and economic matters. The infection causes slow-growing cysts, predominantly in the liver and lungs, but can also develop in other organs. The exact progression of these cysts is uncertain. This study aimed to understand the survival mechanisms of liver and lung CE cysts from cattle by determining their metabolite profiles through metabolomics and multivariate statistical analyses. Non-targeted metabolomic approaches were conducted using quadrupole-time-of-flight liquid chromatography/mass spectrometry (LC-QTOF-MS) to distinguish between liver and lung CE cysts. Data processing to extract the peaks on complex chromatograms was performed using XCMS. PCA and OPLS-DA plots obtained through multiple statistical analyses showed interactions of metabolites within and between groups. Metabolites such as glutathione, prostaglandin, folic acid, and cortisol that cause different immunological reactions have been identified both in liver and lung hydatid cysts, but in different ratios. Considering the differences in the metabolomic profiles of the liver and lung cysts determined in the present study will contribute research to enlighten the nature of the cyst and develop specific therapeutic strategies.

Investigating Pulmonary Hydatidosis: A Narrative Review

Context: Pulmonary hydatidosis (PH) is a zoonotic illness caused by infection with the Echinococcus tapeworm species. About 20% of the infected individuals have lung involvement in this disease, which is epidemiologically secondary to liver disease. Evidence Acquisition: A comprehensive literature search was performed via the Scopus, PubMed, Cochrane Library, and Google Scholar databases. Search terms were "pulmonary hydatidosis," "lung hydatidosis," "Pulmonary echinococcosis," "lung echinococcosis," "Pulmonary hydatid cyst," and "Lung hydatid cyst." The search period of 1980 to 2022 was chosen to compare research from different eras. Results: Echinococcal cysts most frequently develop in the liver and then in the lungs. After a cyst ruptures, the symptoms of lung infestation can cause a quick onset of hemoptysis, fever, coughing, and chest discomfort. Serology is added to radiology to support the diagnosis. The primary investigation for a pulmonary hydatid cyst is a chest x-ray and computed tomography. Surgery or medical treatment may be used to treat PH. The most favored form of treatment is surgical intervention, while medications might be helpful in certain individuals, with benzimidazoles, such as albendazole, as the most common drugs administered orally as part of pharmacotherapy. Conclusion: Given the significant negative effects of PH on individuals, prevention should be emphasized, especially in endemic regions.

A Report of Hydatid Disease Mimicking Asthma in a Child

Hydatid disease is a relatively uncommon finding in children characterized by cystic lesions mostly occurring in liver and lungs, while childhood asthma is one of the most common disorders in pediatrics. In patients with childhood asthma, other diagnoses should be considered and excluded. While the former is curable by an appropriate surgical approach, management of the latter is guided by clinical symptoms and response to therapy. Therefore, timely management of the hydatid disease is valuable in reducing the morbidity. The aim of this case presentation is to demonstrate the value of performing at least one chest x ray in children with asthma features in order to exclude other probable diagnoses. This study reports a 2.5-year old boy with a lung hydatid cyst erroneously being treated as asthma for more than a year. The puzzling signs and symptoms mimicking asthma and the presence of asthma in his father’s medical history led to the false assurance of the treating physicians of their diagnosis and therefore ignoring the need for obtaining a chest x ray in order to exclude other possible etiologies. Later, the persistent lack of response to asthma therapy raised the need for further evaluations including chest x ray which was strongly indicative of pulmonary hydatid disease. To conclude, patients with symptoms akin to asthma in endemic places for hydatid disease should be further evaluated for organic pulmonary diseases by imaging techniques, of which, chest x ray has a significant role as the initial diagnostic procedure.

Comparison of cystectomy and lobectomy of lung hydatid cyst in pediatrics: a retrospective study.

Hydatid cyst is an endemic disease in Iran. The treatment of choice for paediatric lung hydatid cysts is surgical removal of the cyst. However, due to its high prevalence the risk of recurrence after the surgery, cystectomy with capitonnage, which preserves the lung tissue, is a favourable surgical approach compared to lobectomy. Herein, the authors compared the outcome of cystectomy and lobectomy of lung hydatid cysts. This is a retrospective study conducted in the paediatric surgery department. Paediatric patients who had undergone surgery due to pulmonary hydatid cysts were enroled. The patients were divided into two groups including cystectomy and non-anatomic lobectomy. Then, the length of surgery, length of hospitalization, postoperative complications, and the time required to remove the chest tube were calculated in each group. A total of 32 patients were enroled in this retrospective study. Age, sex, location, and size of cysts were not significantly different between the two groups. The duration of surgery in the lobectomy and cystectomy groups was 116.3±33.7 versus 116.1±28.2 min, respectively (P=0.53). Surgery complications including the need for blood transfusion, pneumothorax, need for bronchoscopy and atelectasis were not different between the study groups. The mean time for first chest tube removal was significantly different between the groups with the lobectomy group having a shorter time (P=0.02). The length of hospital and ICU stay were not different between the two surgical procedures. The time to remove the first chest tube was significantly higher in cystectomy compared to lobectomy (P=0.02). The complications and outcome of the cystectomy are comparable to the lobectomy technique. However, the cystectomy method has the advantage of preserving the lung tissue, therefore it's a favourable technique in endemic areas for hydatid cysts where reoperation may be indicated.

A life-threatening encounter: an uncommon case of ruptured hydatid cyst presenting as anaphylactic shock and respiratory distress in a 12-year-old boy

Introduction and importance: Although rare, the spontaneous rupture of a lung hydatid cyst or its perforation into the pleural cavity can give rise to an abrupt onset of symptoms, including cough, fever, hemoptysis (coughing up blood), and hypersensitivity reactions, and can ultimately lead to respiratory failure. Case presentation: A 12-year-old boy was brought to the emergency room with a loss of consciousness. Symptoms included tachypnea, fever, low blood pressure, and overall respiratory distress. After resuscitation, a chest X-ray revealed a distinct, well-defined round opacity located in the lower region of the right lung, leading to mediastinal displacement. After confirmation of the disease, the child was hospitalized in the ICU care and consequently underwent surgery. Treatment was successful and there was no recurrence on the follow-up. Clinical discussion: Studies have demonstrated that the right lower lobe of the lung is the most frequently affected area of the lung by hydatid cysts. Symptomatic and complicated hydatid cysts are a rare concept in children, and only a small percentage, are diagnosed in patients younger than 16 years. Surgery remains the preferred treatment for the majority of patients with pulmonary hydatid disease. It is important to note that combined surgery and chemotherapy represents the current gold standard in managing pulmonary hydatid cyst. Conclusion: Although anaphylactic shock caused by a ruptured lung hydatid cyst is rare, it should be taken into consideration by physicians as a differential diagnosis in patients who also have respiratory symptoms, particularly in endemic areas.

Multiple and bilaterally pulmonary hydatid cystic present as metastas

Hydatid cyst is a parasitic infections of the humans that caused by echinococcus infection. This infection is considerable problem of public health. The most common locations in human body of a hydatid cyst are the liver (75%) and the lung tissue (15%) in the review of medical literature there was a few reports from bilaterally pulmonary hydatidosis which clinically mimics metastatic malignant tumors at initial clinical finding. Because of unusual presentation, the diagnosis with clinical presentations and CT-scan and CXR may easily be missed. For of this missed diagnosis problem, multiple and bilaterally hydatid cyst of lung should be in difrienciated diagnosis of others pulmonary diseases.

Hospital-based retrospective analysis of 224 surgical cases of lung hydatid cyst from southern Iran

BackgroundThe lungs are considered the second-most frequent location for hydatid cyst in human. The current retrospective hospital-based study aimed to assess the epidemiological data, clinical presentation, and treatment outcomes of lung hydatid cyst in patients who underwent surgery for this disease in Fars province, southern Iran.MethodsIn this retrospective study, hospital records of 224 pulmonary hydatid cyst patients were assessed in two main university-affiliated hospitals in Fars Province, southern Iran. Clinical features of patients, epidemiological data, cyst features, surgical interventions, and treatment outcomes were reviewed and analyzed.ResultsA total of 224 hydatid cyst cases of the lung were reviewed. Male patients accounted for the majority of cases (60.4%). The average age of the patients was 31.13 (± 19.6), ranging from 2 to 94 years old. Of the 224 patients, 145 (75.9%) cases had only one single cyst and mostly 110 (53.9%) located in the right lung. Also, 6 (2.9%) cases had cysts in both lungs. The lower lobe of the lungs was the most common location of the hydatid cyst. The average size of lung hydatid cyst was 7.37 cm (SD = 3.86; rang: 2–24) while for the cyst areas was 42.87cm2 (SD = 52.76; range: 2–488). Regarding the surgical method, 86 (38.6%) cases were operated by lung resection surgery while 137 (61.4%) cases had lung preserving one. The chief complaints of the patients were cough (55.4%) and dyspnea (32.6%). Relapse was documented in 25 (11.16%) of cases.ConclusionsLung hydatid cyst is a common infection in southern Iran. Lung preserving surgery is the method of choice for the management of hydatid cyst. Relapse, which was not uncommon in our study, is a challenging feature of hydatid cyst management.

Objective: Lung hydatid cyst is an infectious disease caused by the parasite Echinococcus granulosus. Surgery is the main treatment of the disease in lung hydatid cysts. In our article, we aimed to share our experiences with our patients who underwent surgical treatment for hydatid cysts of the lungs.
 Methods: The data of 41 patients who underwent surgical treatment for pulmonary hydatid cysts in our clinic were analyzed retrospectively. The factors affecting the success of surgical treatment were analyzed.
 Results: Eighteen (43.9%) of the patients were male and 23 (56.1%) were female. There was no statistically significant difference between the size groups in terms of length of hospital stay (p=0.070). No statistically significant correlation was found between the number of lesions and postoperative complications (p=0.367).
 Conclusion: Lung hydatid cysts are a public health problem that can be seen in all age groups. Although different symptoms and complications related to the disease are encountered in lung hydatid cysts, surgery is an effective treatment method with low recurrence, morbidity and mortality.

Our Anesthesia Experience in a Pediatric Patient with Ruptured Lung Hydatid Cyst

Hydatid cyst is a parasitic disease caused by Echinococcus granulosus and transmitted to humans mostly through canine feces. Although it can settle in every organ in the body, the lung is the most frequently involved organ in children.

Surgical Treatment of Hydatid Cyst of Lung; An Experience at Lady Reading Hospital Peshawar

Objective: To evaluate the surgical treatment options for hydatid cyst and their outcomes.
 Study Design: Cross-sectional analytical research.
 Place and Duration of Study: Department of Surgery of Lady Reading Hospital, Peshawar, from Jan 2017 to Dec 2020.
 Methodology: Patients diagnosed and treated for hydatid cyst with pulmonary echinococcosis and operated were included. Inhospital as well as hospital records of 180 patients including intact and complicated cysts ranging from 1-20cm in size that were extirpated and included. Patients diagnosed and treated for hydatid cyst having incomplete medical record and /or lost to follow up were excluded. SPSS version 25.0 was used for data analysis. Quantitative variables were reported using mean and standard deviation while qualitative variables through frequency and percentages. Independent students’ t-test and Fisher’s exact test was used for comparing between the surgical technique groups keeping p-value <0.05 as statistically significant.
 Results: Mean age of patients was 38.59±12.51 years. Mean duration of hospital stay was 11.3±6.1 days. Mean pain on VAS postoperatively was 4.92±2.66. About 102(56.67%) of included patients were male while 78(43.33%) females. Cough was reported in 84(46.67%) of patients, chest pain in 103(57.22%), fever in 24(13.33%), purulent sputum in 31(17.22%), allergic reaction in 17(9.44%), hemoptysis in 4(2.22%) while 29(16.11%) were asymptomatic. About 58% of cases underwent cystotomy and capitonnage, 17% enucleation and capitonnage while 12% pericystectomy, 4% cystotomy and wedge resection and segmentectomy respectively, 3% lobectomy and pneumonectomy in 2% of cases.
 Conclusion: Every surgical approach reported varied outcomes, however the best efficacy with least morbidity and mortality was observed in patients undergoing cystotomy and capitonnage.

A challenging high-risk surgery for necrotizing pneumonia in a right bilobed lung

BackgroundNecrotizing pneumonia is rare in children and is one of the most serious complications of a lung infection caused by antibiotic failure. We present a 12-year-old leukopenic child with a long-lasting lung infection, presenting as having a lung hydatid cyst, but diagnosing with necrotizing pneumonia in the right bilobed lung. Failure to medical treatment and ongoing leukopenia justified surgical intervention with positive results.Case presentationThe patient was referred to our teaching hospital’s pediatric surgery department. He had previously been diagnosed with intestinal tuberculosis (TB) and received anti-TB treatment. On referral to our hospital, the patient was suffering from restlessness, frequent coughing, fever, vomiting, and diarrhea. Following the completion of the clinical work-up, a blood test revealed leukopenia (white blood cell count of 2100/microliter), a normal platelet count, and a lesion in the right lung. Computerized tomography scanning (CT-Scan) image reported a lung hydatid cyst. In the pediatrics ward, a broad-spectrum antibiotics regimen with triple-antibiotic therapy (linezolid, vancomycin, and metronidazole) was instituted and continued for a week with no response, but worsening of the condition. In the pediatric surgery ward, our decision for surgical intervention was due to the failure of medical treatment because of a pulmonary lesion. Our team performed right lung upper lobe anterior segment wedge resection due to necrotizing pneumonia and followed the patient 45 days post-operation with a reasonable result.ConclusionLiving in remote rural areas with low resources and inaccessibility to proper and specialized diagnostic and treatment centers will all contribute to an improper diagnosis and treatment of lung infection. In total, all of these will increase the morbidity and mortality due to lung necrosis in the pediatric population, regardless of their age. In low-resource facilities, high-risk patients can benefit from surgical intervention to control the ongoing infection process.

Atypically Located Hydatid Cyst Cases: Four Unusual Case Reports

Hydatid cysts are frequently located in liver (65-70%) and lungs (25%). The disease is usually asymptomatic when located in the extrahepatic regions. Sometimes, diagnosis can be established by observing germinative membrane, rockwater, or daughter vesicles during the operation.. A 41-year-old female patient applied with the complaint of intermittent left inguinal pain. Echinococcus Indirect Hemagglutination (IHA) test was positive. In the ultrasonographic examination, a hypoechoic area was observed in the posteromedial of the left femoral head.. A 56-year-old female patient, applied with the complaints of intermittent nausea, vomiting, and epigastric pain. She had a history of surgery for liver hydatid cyst 15 years ago and for lung hydatid cyst 10 years ago. IHA test of the patient was positive. The lesion involving septation and accompanied by calcifications around the cyst was reported as a hydatid cyst at dynamic CT for pancreas and upper abdominal MRI. A 22-year-old female patient applied with perianal pain complaint. Drainage was planned for the patient who had a pre-diagnosis of perianal abscess. Tissues similar to the hydatid cyst membrane were excised together with purulent fluid. The patient was diagnosed with hydatid cyst after the pathology result was reported “as compatible with hydatid cyst”. A 32-year-old female patient had a non-metabolic adrenal subcapsular cyst (hydatid cyst?) in the right adrenal gland on ultrasonography performed for abdominal pain. In abdominal tomography, a “cystic mass compatible with hydatid cyst located in the adrenal gland in the upper pole of the right kidney” was reported. IHA test of the patient was negative. Hydatid cysts located in the perianal region and muscles have been reported as atypical localizations in the literature, and some of them were diagnosed as a result of preoperative clinical evaluation and radiological imaging. Some were diagnosed as a result of pathological examination after the operation. Surgical treatment is an option in suitable cases, and the definitive diagnosis can be established by pathology. Consequently, it should be considered that cystic lesions detected in the patients living in endemic regions can be extrahepatic hydatid cyst that is localized in different anatomical regions.

A rare association of brucellosis and pulmonary hydatid cyst in a patient with human immunodeficiency virus

Background: Hydatid disease, or cystic echinococcosis, is a parasitic infection caused by a tapeworm. Pulmonary hydatid infection is the second common manifestation of hydatid disease. We present a patient who was diagnosed with recurrent hydatid cyst in lung and later diagnosed with brucellosis, which is a highly contagious zoonotic disease. Case presentation: A 47-years-old male was diagnosed with pulmonary hydatid disease after a computed tomography (CT) chest-plain was done. As the patient had high intermittent fever for 4 months which could not be explained by an intact cyst in the followup, the patient was diagnosed with brucellosis with both IgG and IgM antibodies positive. Conclusions: Hydatid cyst present with varied symptomatology. A high degree of clinical suspicion combined with meticulous history and clinical examination supported by laboratory investigations are required for its diagnosis. This case highlights the importance of considering brucella as a differential diagnosis. Keywords: hydatid cyst; brucellosis; co-infection; HIV; echinococcus

Prevalence of Some Infections in Liver and Lung of Slaughtered Ruminants in Koya Abattoir, Erbil, Iraq

This study was conducted at the slaughterhouses of Koya / Erbil governorate from (January to December 2013) on 15919 slaughtered ruminants to investigate hydatid cysts, necrosis, fascioliasis, pneumonia, and its frequency. The results showed height significant differences (P<0.01) between different months and between different infections in both sheep and cattle liver, while the differences were insignificant in goats, whereas the differences were significant regarding lung infections in sheep, goats and cattle. The highest percentage of liver hydatid cyst was recorded in sheep especially in February (6.54%) followed by cattle in March (2.17%) and goat in September (0.22%). The highest percentage of liver necrosis was recorded in sheep especially in October (3.43%) followed by cattle in June (1.46%) and goat in July (0.26%). The highest percentage of liver fascioliasis was record in cattle especially in June (2.30%) followed by sheep in March (0.98%) but the goat had no infection throughout the year. The highest percentage of lung hydatid cyst was record in sheep followed by cattle especially in November (17.54 and 10.17%) respectively, followed by goat in September (0.22%). These records was continue for pneumonia, as highest percentage was recorded in sheep then cattle in October (19.71 and 10.22%) followed by goat in February (2.38%).

Pulmonary Hydatid Cyst in Children and Adults: Diagnosis and Management.

Hydatid cyst disease induced by Echinococcus granulosus is a parasitic disease known since ancient times. Today, it continues to be seen in many countries and creates serious problems. The lung is the second most frequently affected organ by hydatid cysts after the liver. Lung involvement is more prevalent in children than adults, and the growth of the cyst is faster in children. Hydatid cysts are mostly seen in the right lower lobe of the lung. Common symptoms are chest pain, cough, and shortness of breath, with the most diagnostic symptom being the expectoration of cyst fluid or membranes. In endemic areas, the diagnosis of hydatid cysts can usually be made easily by clinical findings, serology tests, and radiological findings. When the hydatid cyst ruptures and becomes complicated, it is clinically and radiologically confused with many diseases, especially lung cancer. Surgery is accepted as primary treatment of lung hydatid cysts all over the world. The surgical approach is related to several factors such as the size of the cyst, whether it is intact or complicated, unilateral or bilateral, solitary or multiple, and the presence of destruction of the lung parenchyma. Although it is stated by some surgeons that capitonnage is not required, the most frequently applied surgical technique is cystotomy and capitonnage. Pulmonary resection should be avoided as much as possible, particularly in children. Albendazole or mebendazole treatment in pulmonary hydatid cyst is generally used after surgery and to prevent recurrences.

A Rare Case of Isolated Hydatid Cyst in Right Lung in a Pediatric Patient

Abstract The parasite Echinococcus granulosus is the source of the disease hydatid cyst, which primarily affects the liver but can also affect other parts of the body. This case involves a seven-year-old boy who had fever and cough for 15 days which was identified as a case of isolated hydatid cyst of the right lung following examination and further testing. The child received albendazole preoperatively, then had the hydatid cyst removed with enucleation. After receiving advice to continue taking Praziquantel and Albendazole for another three months, the boy was discharged. If untreated, hydatid cysts of the lung can lead to serious problems like cyst rupture, pneumothorax, and infection and could pose a life-threatening risk. In order to identify hydatid cyst as early as possible, a comprehensive history and examination are crucial, and treatment should begin.

Lung Hydatid Cysts in Children, Evaluation and Surgical Management

Lung Hydatid Cysts in Children, Evaluation and Surgical Management

Cough, with a sac of marbles in the chest.

A 48-year-old male patient presented with productive cough, dyspnea and abdominal pain of 2 months duration. He was diagnosed with diabetes mellitus 6 months ago and had not been regular with his medications. Clinical examination revealed a respiratory rate of 18 per min with room air saturation of 95%, and a paucity of movements with bronchial breath sounds identified on inspection and auscultation, respectively, over the right hemithorax. Chest skiagram and computed tomography images of his thorax are shown below [Figure 1].Figure 1: (a) shows chest skiagram and (b–d) shows high-resolution computed tomography images of the chest. A description of the images is in the accompanying textQuestion: What is the diagnosis? Answer: Pulmonary and hepatic hydatid disease. DISCUSSION The chest skiagram [Figure 1a] revealed a well-defined round radio-opacity in the right mid zone with a crescentic hyperlucent medial margin, called the crescent sign (white arrow). Figure 1b is a coronal view of high-resolution computed tomography (HRCT) scan of the chest lung window, which shows a large cyst in the right lung, with multiple small rounded opacities with fluid attenuation, some of which appear to be floating within it, appearing like a sac of marbles. This is consistent with a diagnosis of a hydatid cyst with multiple daughter cysts within it. There are pockets of air seen between the outer pericyst and inner endocyst, aptly named ‘air-crescent sign’ (blue arrow) and ‘signet ring sign’ (red arrow), which suggest a ruptured or complicated hydatid cyst. Figure 1c, the sagittal section of the HRCT scan of the chest lung window at the level of the aortic outflow tract, shows the ruptured hydatid cyst in the right lung. The daughter cysts have collected in the dependent area of the larger cyst, with some appearing to ‘rise’ over the rest, or the ‘rising-sun sign’ (blue arrow). Also seen is a small air pocket inferiorly (red arrow) between the pericyst and endocyst, called the ‘air-bubble sign’. The presence of air on either side of the endocyst (red arrowheads) gives the appearance of an ‘onion-peel sign’, or the ‘cumbo sign’. Figure 1d shows a large well-defined homogenous cyst in the right lobe of the liver.[1] Blood investigations revealed uncontrolled blood sugar levels. Armed with the characteristic radiology above, and supplemented by a positive serum latex agglutination test for Echinococcus antigen, he was diagnosed with pulmonary and hepatic hydatid disease. He was started on oral albendazole and subsequently underwent pericystectomy of lung cyst along with partial pericystectomy of cyst in the liver. Post-surgery, he is at present asymptomatic and is on regular follow-up. Hydatid disease is a zoonosis, commonly caused by the accidental ingestion of ova of the tapeworm Echinococcusgranulosus, which subsequently develop into larvae in the host intestine and migrate to other parts of the body where they develop into embryos, with the liver and lung being the most commonly involved organs.[1] Characteristic thoracic radiology should lead clinicians to suspect pulmonary hydatid disease, especially when dealing with patients with non-resolving pneumonia or lung mass.
