A case report of bladder paraganglioma and literature review.

Bladder paraganglioma is a rare tumor originated from the chromaffin cells of the bladder. We discuss a case of a 49-year-old male patient with bladder paraganglioma, including the clinical and ultrasonographic features, the histopathological and immunohistochemical manifestations, the treatment and prognosis, and the differential diagnosis of this disease. The combination of ultrasonic examination and clinical manifestations may help to make the accurate diagnosis of bladder paraganglioma, and pathological examination should be used to confirm the diagnosis.
