Mesenteric lipoma

Case contributed by Dr Chris O'Donnell


Incidental finding on duplex ultrasound examination of the aorta for claudication

Patient Data

Age: 80 years
Gender: Male

Echogenic mass in the root of the small bowel mesentery (anterior to the aorta) through which a normal appearing superior mesenteric artery passes (on duplex ultrasound)


CT performed to evaluate the "mesenteric mass" seen on ultrasound

Well defined ovoid fatty mass encasing the mesenteric vessels (SMA/SMV), displacing adjacent small bowel (jejunal) loops.

Case Discussion

Mesenteric lipoma is rare and must be differentiated from panniculitis by its well defined, ovoid shape, and lack of the fat rim/ring sign surrounding the mesenteric vessels. They are usually (but not always) asymptomatic.
