Overview
MRI
Pheochromocytoma
- MRI is the most sensitive modality for identification of pheochromocytomas, and is particularly useful in cases of extra-adrenal location. The overall sensitivity is said to be 98%.[1]
- T1
- Slightly hypointense to the remainder of the adrenal
- If necrotic and/or haemorrhagic then signal will be more heterogeneous
- T2
- Markedly hyperintense (lightbulb sign): this is a helpful feature
- Areas of necrosis/haemorrhage/calcification will alter signal
- T1 C+ (Gd)
- Heterogenous enhancement
- Enhancement is prolonged, persisting for as long as 50 minutes[2]
