Hydatid cyst of the pancreas causing portal hypertension.

Pancreatic localization of hydatid cyst is uncommon. We report a case of a 49-year-old woman who presented with abdominal discomfort, nausea and vomiting. The diagnosis of pancreatic cyst with splenomegaly and portal hypertension was supported on ultrasound, CT-scan and endoscopic ultrasound.
