This case demonstrates the use of 123I-MIBG scintigraphy in the diagnosis of testicular adrenal rest tumours (TART) in an adult with classical congenital adrenal hyperplasia (CAH). TART are common in CAH patients, with MIBG scanning offering a new imaging modality to potentially help verify the diagnosis and prevent invasive investigation.
