Abstract

Here, we report a case of a 70-year-old man referred for an incidentally discovered left renal lesion with peri-aortic lymphadenopathy following a CT scan for back pain. A follow-up MRI scan demonstrated a Bosniak IIF left renal cyst and a T2-hyperintense para-aortic lesion concerning for extra-adrenal paraganglioma (EAP). [131I] Metaiodobenzylguanidine scintigraphy of the para-aortic lesion and urine catecholamines were equivocal. The mass was resected via a robotic approach. Histological examination revealed a haemangioma. Haemangiomas are benign vascular tumours frequently identified on imaging of the liver. Intra-abdominal haemangiomas outside of the liver, however, are rare and may have imaging characteristics that mimic EAP.
