title: Bladder pheochromocytoma with ring calcification.
abstract: A case of a 19-year-old male with a paraganglioma (pheochromocytoma) arising in the prostate and involving the urinary bladder is presented. The radiological studies, including computed tomography, demonstrated ringlike calcification of the tumor, a rare finding that is highly suggestive of the diagnosis of pheochromocytoma. The tumor was excised and found to be malignant at surgery.
