Case Discussion

This was an incidental finding picked up in a patient with weight loss work up. A poorly defined lesion was identified in the pancreatic body with a long segment circumferential mural thickening in sigmoid. Few focal liver lesions are present, some typical of hemangiomas, others possible secondaries.

Identification of duplication of IVC warrants further detailed evaluation of abdomen to rule out any other associated urogenital developmental anomalies
