Overview
Head, neck, chest, and abdominal CT scans may be helpful in the diagnosis of pheochromocytoma.
CT
Radiological evaluation should follow biochemical lab tests to locate site of the tumor. The following findings may be observed on CT scan:[1]
- Most common extra-adrenal locations are superior and inferior abdominal paraaortic areas, the urinary bladder, thorax, head, neck and pelvis.[2]
- In sporadic pheochromocytoma, CT and MRI are good choices. The choice depends on availability and cost.[3]
- In patients with the multiple endocrine neoplasia type 2 (MEN2) syndrome, CT may miss the tumors.[4]
