Multimodal imaging techniques for the diagnosis of congenital left renal arteriovenous fistula: A case report

Multimodal imaging techniques complement each other when diagnosing RAVF, providing detailed diagnostic information that can aid in accurate diagnosis and treatment. In addition, this case reminds the sonographer to pay more attention to the color doppler flow imaging and blood flow spectrum when examining the kidney, so as to avoid misdiagnosis of renal cystic lesions as renal cysts and missed diagnosis of RAVF.
