Figure 1.
Computed tomography angiography (CTA) of an extra-adrenal pheochromocytoma. Abdominal aortic CTA post-processing: (A) maximum intensity projection and (B) shaded surface display show a highly vascularized tumor (thick arrow). The blood supply of the tumor is derived from the right ovarian and right internal iliac arteries (thin arrow). (C and D) Contrast axial CT demonstrates the tumor location at the superior surface of the right ovary, with clear borders.
