CT FINDINGS OF PANCREATIC ADENOCARCINOMA
Abstract
The computed tomographic findings of 18 patients with pancreatic adenocarcinoma were reviewed between January 1993 to December 1999 in King Chulalongkorn Memorial Hospital. The diagnosis of pancreatic adenocarcinoma was confirmed by surgical exploration and biopsy in 16 patients (89%), and fine - needle aspiration (FNA) of peritoneal fluid in 2 patients (11%). CT criteria for unresectable included sign of involvement of the major peripancreatic vessels, signs of distant lymph node metastases, or liver metastases.
All patients fulfilled the criteria of unresectability, was found in our series. CT findings of pancreatic adenocarcinoma including, hypodense pancreatic mass with inhomogeneous enhancement (100%), most commonly at pancreatic head (72%), main pancreatic duct dilatation (50%), IHD and/or CBD dilatation (61%), vascular invasion (72%), contiguous organ invasion (22%), metastases (44%), and adenopathy (72%).
IHD = Intrahepatic duct
CBD = Common bile duct
