Paraganglioma of the urinary bladder with pelvic metastasis

A 52-year-old male, diagnosed with paraganglioma of the urinary bladder, underwent transurethral resection of the bladder tumor 10 years ago. He was lost to follow-up after the operation but was recently admitted to our hospital for the treatment of nasopharyngeal cancer. However, refractory hypertension with palpitation was noted and a computed tomography scan revealed a round, well-defined mass at the right pelvic region. Retroperitoneal tumor excision surgery was performed and a subsequent pathological analysis revealed paraganglioma. The diagnosis of paraganglioma of the urinary bladder with pelvic metastasis was confirmed and his blood pressure returned to normal level without medication after the operation.
