Renal artery aneurysm, Renal cell carcinoma, Kidney preserving


Renal tumors are best diagnosed by contrast-enhanced computed tomography (CECT) abdomen along with history and physical examination. In case of suspicious lesions in respect to location like lesion arising from the bifurcation of renal artery and close to major vessels with all features suggesting of tumor with absent contrast enhancement and absent color flow on Doppler study should be further investigated keeping other possibility of Renal artery aneurysm with thrombus mimicking as renal tumor. CT angiography should be done in every case of suspicious lesion because this will change the further management protocol from Nephrectomy in case of renal tumor to kidney preserving minimally invasive procedure for renal artery aneurysm. Like in this case diagnosis of Renal cell carcinoma was made on the basis of CECT abdomen findings and managed further as per the management protocol for renal tumor but intraoperatively found renal artery aneurysm. On conclusion every suspicious lesion of kidney should be further investigated for renal artery aneurysm so that kidney preserving procedure could be planned preoperatively.
