While most are functional and associated with catecholamine excess, approximately 15% are non\u2010functional, often presenting asymptomatically and discovered incidentally. Due to their rarity, standardized management guidelines are lacking.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation<\/jats:title>\n                    <jats:p>We report a 57\u2010year\u2010old female evaluated for ureterolithiasis who was incidentally found to have a 1.5\u2009cm posterior bladder lesion. Biopsy confirmed paraganglioma. Functional studies, including plasma and urinary metanephrines, were negative, establishing a non\u2010functional tumor. DOTATATE PET\/CT and genetic testing excluded metastasis and hereditary syndromes. At planned transurethral resection, no residual lesion was identified, and pathology was benign. The patient remains asymptomatic on follow\u2010up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n
