Lung hydatic cysts in children: comparison study between giant and non-giant cysts

The aim of this study is to review our experience in pediatric giant pulmonary hydatid cysts focusing on clinical symptoms, location of the cyst, type of the intervention, postoperative complications and long-term results. Between June 2002 and May 2007, 118 children were operated on for hydatid lung cysts. Two groups were defined: Group 1, 32 children with giant hydatid cysts and Group 2, 86 children with non-giant cysts. The statistical significance between the groups was estimated using paired samples t test. The mean age was 11.8 years in G1 and 9.7 years in G2. All of the patients were symptomatic in G1 but only 18% in G2 (P=0.003). The right lower lobe was most frequently involved in both G1 and G2. Surgical parenchymal resection was performed in five patients in G1 (16%) and in 2% in G2 (P=0.033). Postoperative complications in G1 were more significant comparatively to G2 (P=0.003). Giant hydatid lung cysts represent a distinct pathology. They affect essentially adolescents and may reach a large size causing parenchymal destruction. Thus, surgical resections are frequently used and postoperative complications rate is high.

An analysis of clinical features of pulmonary giant hydatid cyst in adult population

Background We performed an analysis of giant hydatid cysts (GCHs) detected in the adult population by comparison with the features of other simple hydatid cysts (CHs) in the light of the relevant literature. Methods The records of 74 adult patients who were operated on in our clinic for pulmonary CHs between 2001 and 2005 were retrospectively evaluated. Cysts that were 10 cm or larger in diameter on any plane were considered GCHs. The cysts were classified into 2 groups as GCHs (group A) and other (group B). The groups were then compared for age, sex, symptom, cyst location, preoperative complications, surgical procedure performed, operative morbidity, and mortality. Results Of 74 patients, 10 (13.5%) were in group A and 64 were in group B. No differences were detected between the clinical presentation, gender distribution, surgical procedure performed, and postoperative morbidity and mortality rates of GCHs and other cysts in adults. In both groups, there were no significant differences between the rates of involvement of 2 lungs ( P = .527). However, both groups had lower lobe involvement, more markedly in group A (81.8% and 45.5% respectively; P = .023). Two patients in group A (20%) and 18 patients in group B (28.1%) had complicated cysts. Conclusions The tendency of GCH to involve the lower lobe of the lung compared to smaller cysts suggests underlying mechanisms other than lung elasticity in the late onset of the symptoms parallel to cyst growth.

Giant hepatic hydatid cyst: A case report

Large type 1 cysts are prone to perforation. Furthermore, insufficient drainage with subsequent abscess is a frequent problem of large cysts. We report here a case of a 19-year old man who was admitted to the hospital with pain in the right upper quadrant and epigastric region. An asymmetrical right upper quadrant enlargement was detected on physical examination. Ultrasonography and computerized tomography revealed a type 1 giant hydatid cyst in the right hepatic lobe, measuring 16 cm in diameter. During operation, partial cystectomy and drainage were done. The large dead space was obliterated by the 'sandwich' method. Omentum and gelatin sponges were used to fill the cavity. The postoperative period was uneventful and the patient was discharged on the 5th postoperative day.

An Aspergilloma in an Echinococcal Cyst Cavity

Aspergilloma is a saprophytic infection which can colonize preexisting lung cavities. The most common underlying diseases are tuberculosis, sarcoidosis, cavitary lung cancer, etc. Although aspergilloma can also occur in operated hydatid cyst cavities, only a few cases have been reported in literature. A 32-year-old female patient underwent cystectomy for the diagnosis of perforated intraparenchymal giant hydatid cyst located in the right upper lobe, reaching down to the hilum. Capitonnage was not performed and it was observed that a residual cavity remained in the cystectomy area. The patient was discharged; however, during clinical and radiological follow-ups, it was found that the residual cyst cavity had expanded. As it was thought that one of the drainage bronchi in the cyst cavity could have opened, the patient was reoperated. During the operation, it was noted that purulent fluid and necrotic tissues were present in the cystic cavity. It was seen that the posterior upper lobe segment was consolidated and not ventilated. Contents of the cavity were removed and the posterior upper lobe segment was resected. Histopathological examination revealed that the tissue in the cavity was that of an aspergilloma, and that chronic organized pneumonia and diffuse interstitial fibrosis were present in the resected segment. Refraining from surgical obliteration (capitonnage) of cyst cavities in cases of giant hydatid cysts extending to the hilum can lead to opportunistic infections such as aspergilloma.

Percutaneous treatment of giant abdominal hydatid cysts: long-term results

This study aimed to evaluate the efficacy of percutaneous treatment of giant abdominal hydatid cysts. In this study, 15 abdominal giant hydatid cysts were treated with the catheterization technique, which included puncture of the cyst, aspiration of fluid, instillation and respiration of hypertonic saline solution, and catheterization and sclerosant therapy with absolute ethanol followed by free drainage of the cavity. The catheter was removed when the daily drainage was less than 10 ml. The goals, including inactivation of the parasite and elimination of the mass effect, were achieved in all patients. Catheterization required a mean of 32 days (range, 14-52 days) and hospitalization a mean of 8.73 days (range, 2-30 days). No evidence for recurrence was observed in any patient during a mean follow-up period of 52.8 months (range, 36-72 months). Percutaneous treatment of giant hydatid cysts is effective because it eliminates both the mass effect and the parasite and alleviates the symptoms. Although the long catheterization time associated with the procedure is unfavorable, it is tolerated by the patients.

Giant Hepatic Hydatid Cyst as a Cause of Small Bowel Obstruction

Today, giant hydatid cysts are fairly rare even in endemic areas. We describe a case of an extremely large hydatid cyst of the liver that was causing massive compression of the neighboring organs, giving rise to a subocclusive syndrome of the intestine. After considering the various approaches available for the treatment of this disease, it was decided that radical surgery was still the best therapeutic choice, especially when extremely large cysts are involved. In particular, in clinical situations where it is difficult to perform radical surgical procedures, less aggressive surgery followed by drug treatment should be the treatment of choice.

The Unusual Mass of Retrovesical Space: A Secondary Hydatid Cyst D?sease

Hydatic cyst of seminal vesicles is very rarely seen. We report a case who complained of the inability to void, which developed progressively with dysuria, frequency, nocturia, and tenesmus, due to a giant retrovesical hydatid cyst that displaced the bladder and rectosigmoid region.

Persistent Pleural Effusion after Open Heart Surgery: Giant Hydatid Cyst of the Liver and its Demonstrative Images. A Case Report

Approximately in 50% of the patients who have undergone coronary artery bypass surgery (CABG), pleural fluid collection occurs at the early postoperative period and resolves spontaneously. CABG was performed on a 54-year-old male. In the early postoperative period, the chest roentgenogram revealed right pleural collection. The preoperative and the postoperative hepatic function tests were nor-mal. MR scanning revealed a giant hydatid cyst at the apex of the liver. The cyst was excised through thoracotomy transphrenically and primary capitonage was applied. In the persistent right pleural effusion that occurs after open heart surgery hydatid cyst of the liver should be remembered, especially in the endemic regions.

Giant Renal Hydatid Cyst Resembling a Simple Cyst: An Intraoperative Diagnosis

An interesting case of a giant renal hydatid cyst is presented. The big cystic mass detected at ultrasonography (US) and computerized tomography (CT) in a ten-year-old girl looked like a simple cyst. No germinative membrane or any other radiological sign of a hydatid cyst was present. The operation was planned for a simple cyst; but was altered, after an intraoperative diagnostic needle sampling brought out the characteristic fluid of hydatid cyst. We came to the conclusion that hydatid cystic masses may not always present with their characteristic radiological findings; and that extreme caution should be practiced by the radiologist and the surgeon in order to prevent iatrogenic echinococcal dissemination.

Giant hydatid cysts of lung and liver

A 13-year-old girl was admitted to our clinic with the complaints of dyspnea, abdominal distention, cough, and right-sided chest pain. The diagnosis of disease was made with physical examination and radiologic evaluation. She underwent right thoracotomy and phrenotomy for the management of the hydatid cysts of the lung and the liver. The postoperative course was uneventful and she was discharged on the 10th postoperative day. We believe that the simultaneous management of concomitant pulmonary and hepatic hydatid cysts through a thoracic route is a convenient option.

Giant Intrathoracic Extrapulmonary Hydatid Cyst Manifested As Unilateral Pectus Carinatum

Liver and lung are the most common sites of hydatid disease, but it can also be seen elsewhere in the body. Extrapulmonary intrathoracic location of the disease is rare. This case of giant intrathoracic extrapulmonary hydatid cyst manifested as unilateral pectus carinatum serves to illustrate that hydatid disease can produce various symptoms and that it may also exist in locations apart from lung and liver.

Giant hydatid cysts of the lung

Background: Hydatid disease is a parasitic infection caused by Echinococcus granulosus, characterized by cystic lesions in the liver, lungs, and, rarely, in other parts of the body. The large cysts in the lung are a special clinical entity called giant hydatid cysts. Characteristics on presentation, operative techniques, and postoperative morbidity and mortality rates in 47 patients with 50 giant pulmonary hydatid cysts 10 cm in diameter or larger were reported in this study. Methods: Cystotomy plus the obliteration of the residual cavity by imbricating sutures from within (capitonnage) was the most frequently used operative technique ( n = 31), followed by pericystectomy plus capitonnage ( n = 6), closure of bronchial openings plus pericystectomy ( n = 6), and lobectomy ( n = 3). Results: The mean age of patients with giant hydatid cyst of the lung was lower than the age of those with usual-sized cysts ( p = 0.04). Five patients had prolonged air leaks (more than 10 days), three had empyema, and one had pneumonia in the opposite lung after the operation. One patient died of cardiorespiratory collapse during the operation. There was one recurrence during follow-up. Conclusions: The increase in the diameter of the cyst in younger ages was correlated with higher lung tissue elasticity and the delay in diagnosis because of delayed symptoms in these patients. Although postoperative complications occurred in 19.1% of patients, all were managed by conservative measures, and there were no indications that the affected lung should have been treated with resection instead of a parenchyma-saving operation.

Surgical Treatment of Giant Hydatid Cyst of the Left Ventricle and Diagnostic Value of Magnetic Resonance Imaging

Cardiac echinococcosis has not been reported frequently. Because of the risk of potentially lethal complications, early diagnosis and definitive treatment are very important The case of a 41-year-old physician, in whom diagnosis of giant left ventricular hydatid cyst was established with cross-sectional echocardiography and magnetic resonance imaging, is presented. The cyst was removed surgically and mitral valve replacement performed because of destruction of the valve.
