Ileus caused by cholesterol crystal embolization: A case report

Figure 1 Abdominal computed tomography-scan showed focal thickening of the wall of the small intestine (a), intestinal dilatation of the oral intestine (b), and intraperitoneal lymphadenopathy (c).

Figure 2 Resected specimen showed a 5-6 cm tumor. The oral side lumen was 1.5-fold bigger lumen than the anal side.

Figure 3 Histologically, we found thickened portions in the wall, muscle plate thickening, fat reduction, fibrosis. The left half of the specimen is lesion area and the right half is normal area (HE × 10).

Figure 4 Cholesterol clefts were detected in the thickened portions in the wall. A: × 20; B: × 200.
