case_images: Preoperative three-dimensional enhanced abdominal CT (transverse view (A), coronal view (B) Multiple, irregular lipoid-like density foci (indicated by red arrow) can be seen in the enlarged small intestinal cavity, that showed no enhancement on the enhanced CT scan. (C) The small intestine appears swirling (red arrow).

case_images: Enhanced abdominal CT revealed a swirling distribution of the small intestine in the right middle and lower abdomen, thickening and narrowing of the local intestinal wall, significant dilation of the area above the lumen stenosis, presence of gas and fluids in the cavity, and multiple irregular lipoid-like density foci in the abdominal cavity that were not enhanced ( Figures 1A-C ).
case_images: The gross specimen revealed lipomas of different sizes densely covering the inner wall of the diseased intestinal cavity.

case_images: Specimen examination revealed that the inner wall of the diseased intestinal lumen was covered with over 100 lipomas of varying sizes, with the largest measuring around 8.0 cm in diameter, in addition to scattered necrotic bleeding points and abnormal mesentery fat distribution ( Figure 2 ).
case_images: Pathological examination showed a submucosal lesion that was composed of mature adipose tissue (HE staining, Ax50, Bx100).

case_images: Postoperative pathological diagnosis indicated small intestinal lipomatosis with local hemorrhage ( Figures 3A, B ).
case_images: Three-dimensional enhanced abdominal CT scan (A transverse view, B coronal view) 20 months after surgery: no recurrence of small intestinal lipomatosis was observed.
