Imaging Findings

Ultrasound shows a left upper pole renal arteriovenous malformation, which measures approximately 2.6cm in diameter (Figure 1). CT urogram shows a lobular mass within the left upper pole kidney, which was indeterminate but suspicious for vascular malformation (Figure 2). Left renal arteriogram shows a large cirsoid type renal arteriovenous malformation. This occupies the majority of the upper and central interpolar kidney (Figure 3). Coronal MRI shows a focal mass like area exhibiting characteristics of a flow void in the upper and central interpolar left kidney (Figure 4).
