Overview
Head, neck, chest, and abdominal CT scans may be helpful in the diagnosis of pheochromocytoma.
CT
Computed tomography: Radiological evaluation should follow lab tests to locate site of the tumour.[1]
- Most common extraadrenal 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.Choosing depends on availability and cost.[3]
- Familial pheochromocytoma – In patients with the multiple endocrine neoplasia type 2 (MEN2) syndrome, computing imaging may miss about one-quarter of the tumors [23]. In a selected group of patients with a 40 percent incidence of pheochromocytoma, the respective positive and negative predictive values of CT were 69 and 98 percent [6].
