Diagnosis and treatment of extra-adrenal pheochromocytoma of urinary bladder: case report and literature review.

Pheochromocytoma of the urinary bladder is often misdiagnosed as it is a rare tumor. In this report, we described a case with primary pheochromocytoma of the urinary bladder. We specifically conversed the diagnostic role of X-ray computed tomography and sonography to identify the location of tumor within urinary bladder compared to other malignant or benign tumors in the bladder, and exclude other ectopic pheochromocytoma. Histopathological report from bladder tissue biopsy was confirmative of extra adrenal pheochromocytoma of the urinary bladder finally. Importance in careful management of hypertensive crisis during cystoscope and partial cystectomy was addressed.
