Figure 1 Abdominal radiography. The dilated intestine with air-fluid levels was prominent in the right middle abdomen.

Figure 2 Abdominal computed tomography scans. Dilated small intestinal loops containing air-fluid levels were clustered in the right middle abdomen and surrounded by a sac-like membrane.

Figure 3 Intraoperative findings. Dilated small intestine was surrounded by a capsular structure in the right middle abdomen, which had a regular surface composed of natural fibrous membranes.

Figure 4 Pathologic examination (HE × 200). The testis with interstitial fibrosis had no spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid, or spermatozoon in the seminiferous tubules.
