Testicular masses in congenital adrenal hyperplasia: Using 123I-MIBG scintigraphy to support the diagnosis of testicular adrenal rest tumours

Abstract

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. Level of evidence: Level 5 case report
