Case Presentation:
A young man came to our hospital with presenting complaint of epigastric pain for few days. Urgent ultrasound abdomen was performed which reported it a pancreatic cyst. The pain was relieved by pain killers. The radiology team was taken on board and CT pancreas dynamic was advised. CT pancreas dynamic was performed with images obtained in noncontract, arterial, venous, and delayed venous phases. The rest of the abdomen and pelvis were reviewed in the venous phase. There was a multilocular and multiseptated homogeneously hypoattenuating/nonenhancing fluid density omento-mesenteric mass predominantly occupying the lesser sac. The lesion was insinuating within the pancreatic body and tail parenchyma as well as along the small bowel mesentery with mild mass effect on the stomach which is anteriorly compressed. It was abutting the left adrenal gland, which was however normal. The pancreatic head and uncinate process appeared normal. It was causing displacement of the small bowel loops and surrounding the transverse colon and splenic flexure. Suspicion of lymphangioma was given on it.
