Case in brief

A 10-year-old boy presented for 18 F-MFBG PET/CT imaging to evaluate a right adrenal lesion. The imaging showed moderate uptake in the lesion and unexpected focal uptake in the lower pole of the right kidney. A prior CT scan indicated renal infarction, and surgical pathology later confirmed a right adrenal pheochromocytoma. This case highlights the importance of considering renal infarction in the differential diagnosis of atypical 18 F-MFBG uptake.

Diagnostic / clinical pearl

Clinicians should be aware that focal 18 F-MFBG uptake in the kidney can be indicative of renal infarction, particularly in the context of adrenal lesions.
