Mesenteric carcinoid with small bowel ischemia

Discussion:

The mesenteric soft tissue mass exhibits typical characteristics of a carcinoid tumor - it exerts a desmoplastic reaction and caused drawing in of the adjacent mesentery and small bowel loops, and it encases and occludes the mesenteric vessels and thereby caused a mixed arterial and venous ischemia of the affected bowel loops. In cases such as this, the mesenteric mass is usually a deposit from a lesion originating in the small bowel that may not be detected. Metastases in the liver are typically hypervascular and optimal detection requires an arterial phase CT to be acquired. Analysis of the surgical specimen confirmed carcinoid.
