A 68-year-old woman presented with episodes of headache, palpitations, sweating and poorly controlled hypertension for the past 6 years. These symptoms were, at times, associated with micturition, and there were few episodes of micturition syncope as well. She had elevated 24-hour urinary normetanephrine and was found to have a paraganglioma arising from the urinary bladder infiltrating the sigmoid colon. She underwent laparotomy with excision of the bladder paraganglioma, following which her symptoms subsided. Paragangliomas are extra-adrenal catecholamine-producing tumours. Bladder paragangliomas need to be considered when evaluating hypertensive patients with headache, palpitations or syncope related to micturition. © BMJ Publishing Group Limited 2020.
