Emergency multimodality imaging for a giant cystic renal artery aneurysm in a lung adenocarcinoma patient with iodinated contrast media allergy: A case report

This case highlights the essential role of multimodal imaging in the emergency diagnosis of RAA, especially in oncology patients with a history of severe allergic reactions to iodinated contrast agents. It also underscores the need for rapid diagnosis and intervention for RAA in patients with malignancies, demonstrating how multimodal imaging enhances diagnostic accuracy while minimizing risks associated with contrast agents.
