Atypical Presentation of Vesical Paraganglioma

Abstract

Paragangliomas are extra adrenal pheochromocytoma arising from the chromaffin tissue of sympathetic nervous system. It accounts for 15% of all the pheochromocytomas. Paraganglioma of urinary bladder is an extremely rare entity and difficult to diagnose in absence of typical symptoms of catecholamines excess. They usually have typical symptoms of hypertensive episodes specifically during voiding or sexual activity. Calcification within paraganglioma is even rare entity and often mimics vesical calculus. Partial cystectomy remains the treatment of choice and confirmation of diagnosis requires immunohistochemical staining. Here we report a case of calcified paraganglioma of urinary bladder with atypical presentation and review of pertinent literature.
