Overview
Head, neck, chest, and abdominal CT scans may be helpful in the diagnosis of pheochromocytoma.
CT scan
- Abdominal, head, neck, and chest CT scans may be helpful in the diagnosis of pheochromocytoma.
- Radiological evaluation should follow biochemical lab tests to locate site of the tumor.
- The following findings may be observed on CT scan:[1]
- Adrenal mass
- Extra-adrenal mass- most commonly in superior and inferior abdominal paraaortic areas, the urinary bladder, thorax, head, neck and pelvis.[2] [3]
- In patients with the multiple endocrine neoplasia type 2 (MEN2) syndrome, CT may miss the tumors.[4]
