Abstract: | Summary A carcinoma in the dorsal part of the pancreas divisum with an annular pancreas in the anterior part is reported. A 79-yr-old
female was admitted in our hospital complaining of epigastralgia. Computed tomography (CT) and ultrasound (US) showed an irregular
mass in the pancreatic body. A pancreatogram obtained through the major duodenal papilla demonstrated only the ventral pancreatic
duct that encircled the duodenum. Contrast medium injected from the minor duodenal papilla showed Santorini’s duct obstruction
at the neck portion of the pancreas without communication with the ventral pancreatic duct. The patient died with liver metastases.
Autopsy confirmed annular pancreas and a 6-cm tumor in the pancreatic body extending to the pancreatic head and pancreas divisum.
Pancreatic carcinoma; histologically a moderately differentiated adenocarcinoma; originated from the dorsal part of pancreas
divisum. To our knowledge this is the first report of pancreatic carcinoma associated with annular pancreas coexistent with
pancreas divisum. |
