Rare etiology of mechanical intestinal obstruction: Abdominal cocoon syndrome

Figure 1 Abdominal radiography, multiple air-fluid levels are seen, which was more prominent in the left upper quadrant.

Figure 2 Abdominal computerized tomography - coronal section; dilated small intestinal loops containing air-fluid levels clustered in the left upper quadrant of the abdomen and surrounded by a thick, saclike, contrast-enhanced membrane in the sections close to the root of mesentery (white arrows). A: Superior; B: Inferior.

Figure 3 Abdominal computerized tomography - coronal section; dilated small intestinal loops containing air-fluid levels clustered in the left upper quadrant of the abdomen and surrounded by a thick, saclike, contrast-enhanced membrane (A) (arrow). The left kidney was also located ectopically at the midline in the abdomen at the level of the pelvis (B) (arrow).

Figure 4 Intraoperative findings; small intestine could not be seen, a capsular structure was identified in the upper left quadrant with a regular surface that was solid-fibrous in nature.
