[Unusual location of multiple hydatidosis, pancreatic and pelvic: about a case].

Hydatid cyst is an infectious disease which is quite frequent in Morocco. Pelvic and pancreatic locations of this parasitic infection are rare, namely exceptional. We report the case of a 66-year old patient who was operated for liver hydatic cyst 6 years before, presenting for chest pain associated with hydatidoptysis. Chest X-ray objectified left hydropneumothorax. Thoraco-abdominopelvic CT showed mediastinal liquid mass as well as multiple hepatic, pancreatic (isthmus), pelvic and left under diaphragmatic cystic lesions. Hydatid serology was positive. Treatment involved thoracotomy associated with medical treatment.
