Which of the following is/ are the imaging criteria for unresectable carcinoma of pancreas?
Ans. is 'd' i.e., All the above Imaging criteria of unresectable pancreatic carcinoma* Vascular invasion is a relative criterion for the lack of resectability, depending on the extent of vascular involvement. A circumferential vessel involvement over 50% makes tumor unresectable, However, in between 25% of vascular invasion makes its resectability questionable.* Metastatic spred outside the pancreas makes tumor irresectable.* Tumor invasion into adjacent organs signifies unresectability.* Ascites is seen in advanced stages and implies peritoneal carcinomatosis or invasion of the lesser sac. Irregular increase in density of the omental fat is highly suggestive of peritoneal carcinomatosis.
Metastatic spread to vertebrae
Invasion in duodenal wall
Irregular increase in density of omental fat
