(B) Hypogastrium CT in November 2022: The arrow displayed that there was slightly entangled intestine with the blurred surrounding fat space in the right pelvic cavity. (C) MRI: The arrow displayed that the bladder filled well.

The patient was considered to have a perforation of the intestine with the hint of the progression of ileocecal ulcer according to his 17-year Behcet's syndrome history ( Figure 2A ). A plain CT scan of the lower abdomen showed a slight accumulation of the right small intestine in the pelvis, a vague surrounding adipose space, and suggested inflammation ( Figure 2B ). Bladder MRI prompted a well-filled bladder ( Figure 2C ).

The result of the capsule endoscopy demonstrated that there were multiple round erosive lesions and depressed lesions in the small intestinal mucosa, circular depressed lesions in the ileum mucosa, congestion, and edema in the peripheral mucosa ( Figure 3 ). Meanwhile, no obvious active bleeding was observed ( Figure 3 ).
