Fig. 1From: Perivascular epithelial cell tumor (PEComa) of the pancreas: a case report and review of previous literaturesImaging studies. a Ultrasonography showed that gourd-shaped hypo- and iso-echoic mass, 56Â mm in size, was detected in the pancreatic head and body. b Enhanced computer tomography showed that solid well-circumscribed low-density mass, 7Â cm in diameter, was located in the pancreatic head and body. c Heterogeneously enhanced mass was detected in the pancreatic body by gadolinium-enhanced MRI. d Endoscopic retrograde pancreatography (ERP) showed that main pancreatic duct was slightly deviated downward because of locoregional pressure effect, but direct invasion to the main pancreatic duct was not evidentBack to article page
