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.[1] The following findings may be observed on CT scan:
- 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]
