CT angiography of renal was an accurate and reliable test for visualizing vascular anatomy and renal artery stenosis and a viable alternative to MR angiography in the assessment of patients with renovascular hypertension and potential living related renal donors. Renal artery stenosis owing to aortic plaque involving the orifice or atherosclerotic narrowing of the main renal artery and the presence of calcified plaque can be detected. Post stent placement MDCTA helps visualize the patency of the stent and renal artery.
Raza and coworkers suggested that MDCTA might be a useful noninvasive screen for renal artery stent restenosis. Arteriovenous malformations, fistulas, and aneurysms can be detected and management decided based on the imaging. Angiomyolipoma can be diagnosed and exquisitely depicted on MDCTA. The feeding arterial branches can be delineated and treatment planning performed based on the findings. The presence of multiple angiomyolipomas in patients who have tuberous sclerosis makes percutaneous catheter embolization a better option to preserve renal tissue.
Thin slab coronal oblique MIP in a pediatric patient demonstrates multiple renal angiomyolipomas (arrows) and prominent vascularity in the left upper and lower pole lesions. And Pre-embolization selective left renal angiogram demonstrates strong correlation with the CT angiography images showing multiple angiomyolipomas (arrows).
