Diagnosis and multidisciplinary management of a large primary retroperitoneal hydatid cyst: report of a sporadic case

BackgroundHydatid cysts, a parasite caused by infestation with Echinococcosis granulose, are rarely found in isolation in the retroperitoneum. Diagnosis is based on clinical and paraclinical criteria, and the symptoms are often aspecific. In large, symptomatic forms, surgical excision is the mainstay of treatment. However, a multidisciplinary approach, including infectious diseases specialists, can improve results and reduce the risk of recurrence.Case presentationWe report the case of a 38-year-old woman presenting with a large primary retroperitoneal hydatid cyst. After 13 years of asymptomatic evolution, she developed lumbar pain and a sensation of heaviness. The diagnosis was confirmed by a battery of biological and radiological tests. Due to the size of the cyst, open surgery was performed. Follow-up revealed no clinical complaints or recurrences.ConclusionConsidered a rare condition, hydatid cyst requires special attention when evaluating lumbar masses or cystic masses, particularly in endemic areas. In addition to surgery, it is essential to take into account the risk of contamination of other sites during surgery. Collaboration with specialists in infectious diseases is therefore essential.

Primary retroperitoneal hydatid cyst with intraperitoneal rupture: a case report

BackgroundHydatid disease is endemic in Mediterranean countries and most commonly occurs in the liver followed by the lung. A primary localization in the retroperitoneum is extremely rare.Case presentationWe report the case of a 29-year-old Tunisian patient presenting with progressive left flank pain and skin urticaria. On abdominal ultrasonography and computed tomography scan, a ruptured retroperitoneal hydatid cyst was diagnosed, which was confirmed by positive hydatid serology. The treatment consisted of resection of protruding dome. The evolution was favorable. No local recurrence was detected during postoperative follow-up.ConclusionsPrimary retroperitoneal hydatid cyst is extremely rare and has uncommon presentation, but we should learn the keys to its diagnosis. In endemic regions, high suspicion for this disease is justified regardless of localization.

Primary retroperitoneal hydatid cyst in pancreatic head region

A hydatid cyst in retroperitoneal space is uncommon and one in the pancreatic head region is rare. We hereby report a case of a 20-year-old male presenting with a retroperitoneal hydatid cyst of the pancreatic head region. Investigations revealed no hydatid cysts in other organs of the body. The diagnosis was confirmed at laparotomy and partial pericystectomy was performed. Hydatid cyst should be considered in the differential diagnosis of cystic lesions of retroperitoneal area.------------------

Retroperitoneal hydatid cyst at a rare site- a case report

Hydatid disease in humans is caused by the parasite Echinococcus Granulosus. It is most commonly found in liver and lungs. Primary Retroperitoneal Hydatid cyst is extremely rare and constitutes only 0.8% of total cases. We present a case of a 42 year old female who presented with a historyof gradually increasing abdominal mass. A clinical diagnosis of Pancreatic cystic neoplasm was made and Whipple's procedure was performed. A histopathological diagnosis of Retroperitoneal Hydatid cyst was given. The diagnosis of hydatid disease should be considered in the differential diagnosis of all cystic lesions at all anatomic locations, particularly in areas where the condition is endemic.

Retroperitoneal Hydatid Cyst Masquerading as a Retroperitoneal Cystic Tumor

Hydatid disease is an endemic disease, with canines the primary host and humans the intermediate host. Liver, spleen and lungs are most common involved organs, but it can involve any organ. Retroperitoneal hydatid cyst are categorised into two types, primary and secondary. Primary retroperitoneal hydatid cyst is rare disease, with most of the cases diagnosed intra-operatively, hence pre-operative high index of suspicion for any retroperitoneal cystic lesion to prevent inadvertent complication intra-operatively is of utmost important. 25-year male patient presented with right flank pain for 3 months, high grade fever for 10 days. On cross sectional imaging a retroperitoneal cystic lesion of size 7.1×7.6 cm was noted. Leucocytosis was present and rest of the blood parameters were with in normal limits. Patient was planned for surgery with a diagnosis of the retroperitoneal cystic tumour with possible tumour degeneration. On exploration 8×8 cm pelvic retroperitoneal hydatid with daughter cysts and purulent material noted. Diagnosis of infected retroperitoneal hydatid cyst was made and cyst de-roofing and drainage was done. Final diagnosis of hydatid cyst was confirmed by histopathology report. The retroperitoneal hydatid cyst is a rare entity even in endemic areas. First reported in 1958 by Lockhart and Sapinza, an isolated retroperitoneal hydatid cyst could be caused by haematogenous dissemination of protoscoleces after bypassing the liver (veno-venous shunts within the liver and in the space of Retzius) and the lungs or by the gastrointestinal tract into the lymphatic system. Dew and Waddle had favoured airborne transmission and direct implantation of the embryo in the bronchial mucosa as another possible mode of entry. This raises the possibility of an embryo of the parasite entering a venule after penetrating the bronchial mucosa and reaching the left side of the heart to involve other sites and thus bypassing the lung. Spontaneous, traumatic, or surgical rupture of a hepatic cyst may also give rise to cysts in retroperitoneum. The definitive diagnosis of a retroperitoneal hydatid cyst requires a combined assessment of clinical, radiological and serological analysis. Definitive treatment is total cystopericystectomy. Though retoperitoneal hydatid cyst are rare, diagnosis should be considered if any retroperitoneal cyst lesion is noted to prevent the complications of the cyst rupture. The gold standard treatment is total cystopericystectomy. If complete resection is not possible, cyst de-roofing, drainage and adjuvant anti-helminthic should be considered.

Primary retroperitoneal hydatid cyst: a rare case with atypical presentation

Primary Retroperitoneal Hydatid Cyst is a rare presentation of a disease caused by Echinococcus granulosus. Any organ of the body could be affected by the disease, although there are only a limited number of cases where the primary lesion is in the retroperitoneum. A definitive diagnosis requires a combination of imaging, serologic and immunologic tests. Ultrasonography, computed tomography and magnetic resonance imaging are highly accurate in detecting a hydatid cyst. Diagnosis of retroperitoneal hydatid cysts remain difficult as the clinical and laboratory findings are usually nonspecific. We report a case of a 47-year-old male who had an incidental finding of a retroperitoneal mass behind the left kidney. The CT scan of abdomen was suggestive of Retroperitoneal Hydatid Cyst. Patient underwent marsupialisation of cyst. Histopathological Report was suggestive of Hydatid Cyst.

Retroperitoneal Hydatid Cyst: Case Report

Hydatid disease (HD) is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Herein we report a new case of primary retroperitoneal hydatid cyst diagnosed with abdominal pain and palpable large mobile mass on the right side of abdomen.

Isolated Retroperitoneal Hydatid Cyst Invading Splenic Hilum

Introduction. Hydatid disease (HD) is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT) revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR) technique is another nonsurgical option.

Left retroperitoneal hydatid cyst disease and the treatment approach

Hydatid disease is one of the oldest diseases known to mankind. In 85-95% of the cases, the liver and/or the lung are involved and in only 5-15% the cyst occurs at the other sites. Echinococcal cysts are mostly found in the liver (60%-70% of cases), followed by the lungs (10%-25%), spleen, ovaries, kidneys, brain, bones and heart, but rarely elsewhere in the body.1-3 Retroperitoneal location of hydatid cyst is encountered rarely and only occasional case reports have appeared since Lockhart and Sapinza first reported this entity in 1958.4-6 Primary retroperitoneal hydatid cyst is extremely rare. Hydatid disease in extrahepatic locations usually remains asymptomatic unless the cyst grows and produces symptoms due to pressure, rupture to the pleural or peritoneal cavity, secondary infection, or an allergic reaction. The differential diagnosis of a retroperitoneal cystic mass includes soft tissue tumors, cystic lymphangioma, retroperitoneal abscess, pseudocyst, and embryonal cysts.7-8 We reported a rare case of a 21-year-old woman with a hydatid cyst in her left retroperitoneum, with concomitant left diaphragmatic involvement.

An Extraordinary Cause of Low-Back Pain and Foot Drop: Hydatid Cyst

Low-back pain is a clinical problem that is observed very frequently. Hydatid cyst is a disease that is created by Echinococcus granulosus and characterized by a cystic mass which grows slowly. The liver and the lungs are the most common organs involved in the E. Granulosis infections; however, retroperitoneum may also primarily be involved in rare cases. If retroperitoneal cystic mass is determinated in the endemic regions, hydatid cyst should be considered as a cause. We report a case with a rarely observed and lately-diagnosed primary retroperitoneal hydatid cyst at the lower abdominal MRI, which has caused peripheral nerve pressure.

Hydatid Cyst Presenting as Ovarian Tumor

Background: Hydatid disease is a parasitic infection caused by the larval stage of the tapeworm Echinoccocus granulosus. A primary retroperitoneal hydatid cyst is very rare. Such a case is reported here, which was wrongly diagnosed as an ovarian cyst. Case: A 27-year-old woman presented as a case of ovarian cyst. She had a history of two laparotomies for ovarian cysts. She was found out to be a case of hydatid cyst, which was removed surgically. Conclusions: The possibility of an hydatid cyst should always be kept in mind when a septated mass is found in the pelvis. (J GYNECOL SURG 28:434)

Case report of primary retroperitoneal hydatid cyst

Hydatid cyst develops in retroperitoneal space without accompanied lesion in other organs is defined as primary retroperitoneal hydatid cyst. It is extremely rare though hydatid cyst may affect every organ in human body. A 15 years old boy presented with a giant retroperitoneal cyst and hydatid cyst was suspected. Thorough examination did not revealed lesions in liver, lung, kidney or other organs. The diagnosis was confirmed through laparotomy. The diagnosis is difficult, but the possibility should be considered before operation to prevent spillage or fatal anaphylactic shock. Living in an endemic area, ultrasonography, CT or serology test is helpful in the diagnosis of this disease. Total cystectomy is the ideal surgery, if not possible or at high risk, partial pericystectomy is acceptable.

Primary hydatid cyst masquerading as pseudocyst of the pancreas with concomitant small gut obstruction—an unusual presentation

Isolated retroperitoneal hydatid cyst is an exceptionally rare entity. Owing to vague and varied symptomatology, it is seldom diagnosed without puncture cytology or surgery. We report an unusual presentation of primary retroperitoneal hydatid cyst with concomitant small gut obstruction. Ultrasonography and computed tomography of the abdomen showed localized abscess or pseudocyst of pancreas. Preoperatively, ultrasound-guided puncture cytology of the lesion revealed suspicious hydatid pathology. The patient was examined and, peroperatively, the cyst masqueraded as hydatid cyst of pancreas along with an inflammatory band, and the diagnostic dilemma about its exact site of origin was solved by histopathology only. Complete excision of the cyst along with the tail of pancreas was done with concomitant excision of inflammatory band, causing small intestinal obstruction. The patient was discharged in satisfactory condition on albendazole. In follow-up of 8 months, there was no recurrence.

Laparoscopic management of a large primary retroperitoneal hydatid cyst.

Hydatid cysts usually involve the liver and lungs, but any other organ can potentially be involved and these can mimic numerous pathologies; however, primary involvement of the retroperitoneum and presentation as a left-sided abdominal mass is quite unusual. A 30-year-old male presented with a large cystic lump in the left side of the abdomen that was diagnosed as a primary retroperitoneal hydatid cyst by a computed tomography scan and serology. The patient was managed successfully by minimal access surgery. This report highlights that a primary retroperitoneal hydatid cyst is a rare clinical entity and should be considered as one of the differential diagnoses in patients presenting with a cystic mass in the retroperitoneum. In the present era of minimal access surgery, it can be safely managed with a laparoscopic approach.

Retroperitoneal Hydatid Disease

Localization of hydatid disease in the retroperitoneal space is extremely rare. We reported a recent case with primary retroperitoneal hydatid cyst, the diagnosis of which was established before surgery. In diagnosis of a cystic retroperitoneal mass, fine needle aspiration biopsy would be useful for planning the definitive surgical strategy.

Primary retroperitoneal hydatid cyst: A case report

Retroperitoneal echinococcal cyst is a rare manifestation of hydatid disease. Hydatid disease is an endemic parasitic disease of the Mediterranean countries [1]. Although the liver and lungs are the most commonly involved organs, the disease may be found in any part of the body. We present here an experience of treating a patient with retroperitoneal hydatid presenting as al tumor. Keywords : echinococcosis, retroperitoneal hydatid cyst, India.

EXTRAVISCERAL PRIMARY HYDATID CYST OF THE RETROPERITONEUM

Hydatid cyst (HC) continues to be endemic in the Mediterranean countries, such as Turkey. Living in a rural area is an important risk factor for the disease. HC is most commonly seen in the liver and lungs, but retroperitoneal hydatid cyst is very rare. The objective of this study was to evaluate the clinical and radiographic findings and surgical treatment of this unusual lesion. Between 1979 and 2004, 14 cases with primary retroperitoneal hydatid cyst were treated surgically at our clinic. Symptoms included flank pain in eight (57.1%) and palpable mass in six patients (42.8%). The cyst was located in the right retroperitoneum in seven patients (50%), left retroperitoneum in five patients (35.7%), retrovesical region in one patient (7.1%) and paravesical region in one patient (7.1%). Surgical approaches were right paramedian extraperitoneal approach in four patients, left paramedian extraperitoneal approach in two patients and midline transperitoneal approach in eight patients. Total pericystectomy was chosen as the surgical procedure in all patients except in five (35.7%), who had partial cystectomy for cysts located near the vital structures. There were no complications and mortality postoperatively. A primary HC of the retroperitoneum is a distinct clinical entity that must be considered when caring for a patient with a retroperitoneal mass in endemic regions. It should be treated after the diagnosis is confirmed without any delay because of secondary spillages due to perforations and other possible complications.

Primary retroperitoneal hydatid cyst.

Abstract A case of a primary retroperitoneal hydatid cyst in an Indian adult which was treated by marsupialization is described. Attention is drawn to the rarity of the lesion, the probable mode of spread, and the difficulties encountered in its diagnosis.
