A rare case of non-functioning bladder paraganglioma treated with robotic assisted partial cystectomy

Abstract

Primary bladder paraganglioma is rare. A 57-year old man presented with a mass in the inferior wall of the bladder identified on computerized tomography imaging. We investigated the mass with office cystoscopy followed by transurethral resection, which was found to be a nonfunctioning paraganglioma. 68Ga-DOTA-conjugated somatostatin receptor-targeting peptide positron emission tomography revealed no other locations of the disease. The mass was then completely removed through robotic assisted partial cystectomy. Succinate dehydrogenase B immunohistochemistry was normal, arguing against a succinate dehydrogenase-deficient paraganglioma. Keywords: Bladder, Paraganglioma, Partial cystectomy
