Presentation transcript:

Comparison of imaging methods: metastatic extra-adrenal familial pheochromocytoma. 10-year-old boy with hypertension and seizures precipitated by abdominal palpation. Family history of multiple extra-adrenal pheochromocytomas in the mother. Upper left: Excretory urogram. The right ureter is dilated and elevated (curved arrow), with the right posterior portion of the bladder displaced toward the left (straight arrow). The urographic diagnosis is possible extra-adrenal paravesical pheochromocytoma. Upper right: Right femoral arteriogram. Tumor stain (arrow) in right paravesical location. The angiographic diagnosis is extra-adrenal paravesical pheochromocytoma. Lower left: Computed tomography (CT) scan. Transverse tomogram through bladder (B) shows the tumor (T) indenting the bladder (arrows). R = rectum. Lower right: CT scan. Transverse tomogram through bladder. Recurrence of symptoms following removal of the right paravesical pheochromocytoma prompted another CT study, which shows recurrent tumor (arrow) in the bladder wall. Each imaging study complemented or supplemented the previous one. None, however, diagnosed the small liver metastases discovered at surgery. Source: Chapter 6.
