“…They can be congenital, acquired or idiopathic. [1] Benign vascular lesions are classified as hemangiomas, lymphangiomas, vascular ectasias, reactive vascular malformations and glomus tumors. Hemangiomas are further divided into pyogenic granulomas, capillary and cavernous hemangiomas.…”

Renal arteriovenous malformation with inferior vena caval extension mimicking renal cell carcinoma

A young lady presented with complaints of right flank pain and a palpable mass. On contrast-enhanced tomography (CECT), a renal mass with extension into the inferior vena cava (IVC) - suggestive of renal cell carcinoma - was diagnosed and she underwent radical nephrectomy with en bloc excision of the IVC thrombus. Histopathology revealed a benign arteriovenous malformation that had extended into the IVC. Arteriovenous malformation should therefore be kept in the list of differentials for a renal mass with IVC extension.

“…Other characteristic findings include a pseudoaneurysm, extravasation of contrast material, and, in cases of congenital AVM, a tangle of coiled vascular structures. 1 The management of renal AVMs can differ, depending on their size and vascularity. Nephron-sparing surgery, nephrectomy, and vascular embolization have all been advocated.…”

We describe a renal arteriovenous malformation in a patient with a 1-month history of flank pain. Imaging studies were interpreted as being consistent with renal-cell carcinoma. However, Doppler ultrasonography demonstrated turbulent blood flow, and selective renal angiography confirmed the diagnosis of an arteriovenous malformation. Embolization relieved the pain. This case calls attention to the need to consider arteriovenous malformations in the differential diagnosis of central homogenously enhancing renal lesions.
