Echinococcal cysts usually involve the liver; extrahepatic localization is reported in 11% of all cases of abdominal hydatid disease. We report a case of a prevesical hydatid cyst. A 53-year-old man was admitted with a large suprapubic mass. Ultrasonography and computed tomography revealed a cystic mass situated in front of the urinary bladder. There were no cysts in any other location. Serological tests were positive for Echinococcus. The patient was operated on and the cyst was completely excised. The pathologic examination confirmed the diagnosis of Echinococcosis. Isolated hydatid cyst situated in front of the urinary bladder has never been described in the literature. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions, before any procedure like puncture, biopsy or cystectomy, in order to avoid dissemination of the cystic contents or an anaphylactic shock.

Primary hydatid cyst of the adrenal gland remains an exceptional localization. The adrenal gland is an uncommon site even in our country in which echinococcal disease is endemic. We report the case of a 38-year-old woman who consulted for left back pain. The CT scan showed a cystic mass in the left retroperitoneal area with a calcified wall. The patient underwent surgery which confirmed a diagnosis of hydatid cyst of the left adrenal gland. The surgical treatment consisted on a total resection of the cyst, without rupture of the cystic wall and preserving the gland. The diagnosis was confirmed on macroscopic and histological examination of the resected piece. The postoperative course was uneventful. No recurrence had occurred after 36 months of follow-up.

Introduction: Heterotopic pancreatic (HP) tissue defined as tissue that is found outside the anatomical location of the pancreas. It can occur anywhere in the gastrointestinal tract with the stomach and small bowel being the most common sites. The diagnosis of HP is considered difficult and usually discovered as an incidental finding in laparotomy. However, it can present as a case of intussusception or even perforation. Case Presentation: In this case, we report a 23-year-old male with a history of abdominal pain with vomiting that lasted for 7 days. Computed tomography (CT) scan was suggestive of intussusception. Laparotomy was done and a mass was found adherent to the jejunal wall. Partial resection of the jejunum was performed including the mass. The histopathological analysis confirmed it to be mixed exocrine and endocrine heterotopic pancreatic tissue. Conclusion: Heterotopic pancreatic tissue in the jejunum is rare. However, it should be considered in the differential diagnosis of jejunal masses.
