Non‐Functional Paraganglioma of the Urinary Bladder: A Rare Cause of Bladder Tumor

IJU Case Reports, Volume 9, Issue 2, March 2026.
ABSTRACT Introduction Paragangliomas of the urinary bladder (PUBs) are rare neuroendocrine tumors, representing less than 0.06% of all bladder neoplasms. While most are functional and associated with catecholamine excess, approximately 15% are non‐functional, often presenting asymptomatically and discovered incidentally.
