Total atrophy of the body and tail of the pancreas with a small focus of tissue in the neck that the raises the question of a neoplasm. Marked biliary ductal dilatation which suddenly ends in the head of the pancreas in a pattern consistent either with a small pancreatic head tumor or post-inflammatory stricture.Enlarged lymph node in the gastrohepatic ligament makes the likelihood of tumor more likely.
