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.<\/jats:p>","DOI":"10.1136\/bcr-2020-235353","type":"journal-article","created":{"date-parts":[[2020,9,3]],"date-time":"2020-09-03T02:35:23Z","timestamp":1599100523000},"page":"e235353","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Micturition syncope: a rare presentation of bladder paraganglioma"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0909-2752","authenticated-orcid":false,"given":"Neethu","family":"Sunil V","sequence":"first","affiliation":[{"name":"Internal Medicine, Christian Medical College, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3382-0294","authenticated-orcid":false,"given":"Kevin","family":"John","sequence":"additional","affiliation":[{"name":"Internal Medicine, Christian Medical College, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2484-5433","authenticated-orcid":false,"given":"Sultan","family":"Nawahirsha","sequence":"additional","affiliation":[{"name":"Internal Medicine, Christian Medical College, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ramya","family":"Iyyadurai","sequence":"additional","affiliation":[{"name":"Internal Medicine, Christian Medical College, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,9,2]]},"reference":[{"key":"2025082722480914000_13.9.e235353.1","doi-asserted-by":"crossref","first-page":"68","DOI":"10.1016\/j.ejim.2018.01.015","article-title":"Incidence of pheochromocytoma and sympathetic paraganglioma in the Netherlands: a nationwide study and systematic review","volume":"51","author":"Berends","year":"2018","journal-title":"Eur J Intern Med"},{"key":"2025082722480914000_13.9.e235353.2","doi-asserted-by":"crossref","DOI":"10.1186\/1471-2490-13-22","article-title":"Pheochromocytoma of the urinary bladder: a systematic review of the contemporary literature","volume":"13","author":"Beilan","year":"2013","journal-title":"BMC Urol"},{"key":"2025082722480914000_13.9.e235353.3","doi-asserted-by":"crossref","first-page":"213","DOI":"10.1007\/s12022-017-9484-5","article-title":"Update on adrenal tumours in 2017 World Health organization (who) of endocrine tumours","volume":"28","author":"Lam","year":"2017","journal-title":"Endocr Pathol"},{"key":"2025082722480914000_13.9.e235353.4","doi-asserted-by":"publisher","DOI":"10.1007\/s00268-007-9360-4"},{"key":"2025082722480914000_13.9.e235353.5","doi-asserted-by":"publisher","DOI":"10.1196\/annals.1353.002"},{"key":"2025082722480914000_13.9.e235353.6","first-page":"137","article-title":"Pheochromocytoma of the urinary bladder: report of 2 cases and review of literature","volume":"60","author":"Siatelis","year":"2008","journal-title":"Minerva Urol Nefrol"},{"key":"2025082722480914000_13.9.e235353.7","doi-asserted-by":"crossref","first-page":"194","DOI":"10.4158\/EP.15.3.194","article-title":"Comparison of pheochromocytomas and abdominal and pelvic paragangliomas with head and neck paragangliomas","volume":"15","author":"Al-Harthy","year":"2009","journal-title":"Endocr Pract"},{"key":"2025082722480914000_13.9.e235353.8","doi-asserted-by":"publisher","DOI":"10.5732\/cjc.009.10703"},{"key":"2025082722480914000_13.9.e235353.9","doi-asserted-by":"publisher","DOI":"10.1210\/jc.86.11.5210"},{"key":"2025082722480914000_13.9.e235353.10","doi-asserted-by":"crossref","first-page":"1067","DOI":"10.3892\/etm.2013.1242","article-title":"Unsuspected paraganglioma of the urinary bladder with intraoperative hypertensive crises: a case report","volume":"6","author":"Li","year":"2013","journal-title":"Exp Ther Med"},{"key":"2025082722480914000_13.9.e235353.11","unstructured":"Pacak K , Tella SH , et al .
