case_images: CT abdomen/pelvis revealing a 33 x 27 x 15 cm, predominant fatty mass with multiple septa and a few areas of soft tissue density. The mass displaces most of the abdominal contents posteriorly. A loop of small bowel is seen within thin the mass. No evidence of obstruction noted as oral contrast reached the sigmoid colon. (A) Coronal (B) Sagittal (C) Axial views.

case_images: He was then sent for a CT of the abdomen and pelvis, which again noted an abdominal mass 27 x 33 x 15 cm in size that displaced the majority of his abdominal contents posteriorly and that appeared to be mesenteric in origin (Figure 1).
case_images: Images of the gross specimen. (A) mesenteric lipoma in situ. (B) The lipoma was connected to a single pedicle of mesentery accompanied by a loop of small bowel entering through the mass. (C) Gross specimen after resection with one loop of small bowel (black arrow).

case_images: On exploration, the mass was tan-yellow in color, firm with a rubbery consistency, involved a segment of small bowel, and was connected via a single vascular pedicle (Figure 2).
