Dilated, fluid-filled bowel loops (jejunal and proximal ileal loops) up to 3.2 cm. A sac-like cluster of distended small bowel loops with feces sign is noted in the right supa-and paravesical region, herniating through the supravesical fossa, and displacing the bladder to the left. Mild peritoneal effusion is seen.
Small umbilical hernia of epiploic content is noted.
Paravesical internal hernias are an extremely rare form of internal hernias 2. Three categories are described anterior, right or left lateral, and posterior, depending on their position to the bladder 1.
