Fig. 1From: Conversion surgery for undifferentiated carcinoma with osteoclast-like giant cells of the pancreas: a case reportComputed tomography showed the pancreatic mass which was 7.5 cm in size at initial diagnosis (A, arrowhead). It revealed portal vein embolism (A, arrow), which was suggestive of tumor emboli at the main trunk and stenosis of the main pancreatic ducts with distal dilatation of the pancreatic duct (A). Magnetic resonance cholangiopancreatography exhibited the main pancreatic duct (MPD) stenosis at the pancreatic head with distal dilatation of MPD (B). After ten cycles of chemotherapy with FOLFIRINOX, the tumor shrunk to 3 cm (C, arrowhead), and the thrombi in the main portal vein could not be identified (C)Back to article page
