Large well-defined pelvic multiloculated cystic mass of intraperitoneal location in the rectovesical pouch, compressing and displacing the urinary bladder. It elicits a low signal on T1 and a high signal on T2 with no enhancement on postcontrast sequences. No evidence of fatty components or mural calcification.
Case Discussion
The MRI features of a multiloculated pelvic cystic mass in a patient with a previous history of surgery for a hepatic cyst are highly suggestive of a hydatid cyst, which was confirmed at surgery.
