From: Parasitic diseases as a cause of acute abdominal pain: imaging findings
A 16-year-old girl was admitted to the emergency department with an acute onset of right upper quadrant pain and fever. a Axial contrast-enhanced CT image demonstrates the imaging findings of intraperitoneal rupture of a hydatid cyst. Focal outward bulging found at the lateral wall of the cyst indicates the site of rupture (arrowheads, a). Mild fluid collection adjacent to the hepatic capsule was also noted (asterisk). b Axial CT image from lower abdomen shows mural thickening of the jejunal loops (arrows) and adjacent fat tissue stranding (arrowheads) indicating the local allergic reaction of bowel wall secondary to ruptured hydatid cyst. Surgical findings confirmed the intraperitoneal rupture of the hydatid cyst
