Overview
Head, neck, chest, and abdominal MRI may be helpful in the diagnosis of pheochromocytoma.
Key MRI Findings in Pheochromocytoma
- T1 slightly hypointense to the remainder of the adrenal gland, if there is a necrosis and/or haemorrhage then the signal will be more heterogeneous
- T2 markedly hyperintense (lightbulb sign, helpful in the diagnosis), areas of necrosis/haemorrhage/calcification will alter signal
- T1 C+ (Gd) heterogenous enhancement is prolonged, persisting for as long as 50 minutes
Patient #1: Bladder pheochromocytoma
Patient #2: Abdominal pheochromocytoma
