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.
