RESUMO
Brunn nests are the most common proliferative lesions of the bladder uroepithelium, but exuberant proliferation can mimic bladder tumor on radiologic imaging and cystoscopy. We describe a case of pathologically proven Brunn nests in a 34-year-old man, misdiagnosed as bladder tumor on preoperative imaging studies.

Polypoid cystitis is a rare entity and, to our knowledge, has not been described in the radiologic literature.It is frequently found in patients with indwelling catheters and is characterized by inflammation and edema of thelamina propria. We encountered a case of papillary cystitis which on a sonogram showed a solid mass withinhomogeneous internal echopattern ; on CT, a poorly-defined inhomogeneous, dense, soft-tissue density mass withenhancement and perivesical extension ; and on T2 weighted MR images an inter mediate SI mass.
