Complete eversion and prolapse of bladder concurrent with primary adenocarcinoma

Complete eversion and prolapse of the urinary bladder is extremely rare. To the best of our knowledge, the imaging findings of complete bladder eversion have not been documented in the literature. Here, we report a case of complete eversion and prolapse of the urinary bladder demonstrated on MRI. Concurrent primary adenocarcinoma was found in the thickened wall of the everted urinary bladder.
