Abstract
BACKGROUND Diffuse intestinal lipomatosis is a rare condition that infiltrates mature fatty tissue into the intestinal submucosa and subserosa of the small or large intestine and can present with intestinal obstruction or torsion. This report is of the case of a 58-year-old woman who had acute torsion of the small bowel due to diffuse small intestinal lipomatosis. CASE REPORT A 58-year-old woman, who was otherwise in good health, arrived at our Emergency Department experiencing sudden, intense pain in the lower abdomen. She also reported abdominal swelling, feelings of nausea, vomiting, and reduced ability to defecate for at least 2 days. The next morning, contrast-enhanced abdominal computed tomography (CT) scan was performed, showing diffuse thickening of the small intestinal wall with hypodensity, fatty density, lumen narrowing, and wall thinning. The small intestine demonstrated a whirlpool-like distribution in the lower right abdomen and localized thickening of the small intestinal wall, suggesting acute intestinal torsion. An hour later, an emergency operation was performed to remove part of the small intestine. Three days later, pathological results showed a thin intestinal wall, expansion of the mucosal layer and submucosa, and hyperplasia of adipose tissue. CONCLUSIONS This report presents a rare case of torsion and small bowel obstruction caused by diffuse intestinal lipomatosis and focuses on the abdominal enhanced CT scan, which showed diffuse thickening of the small intestine, with multiple areas of fat density and torsion of the small intestine in the right lower abdomen. Histopathology is also presented, with the result showing intestinal lipomatosis.
