# An Unusual and Challenging Association of Renal Artery Aneurysm and Renal Cell Carcinoma That Underwent Laparoscopic Partial Nephrectomy

## TL;DR

This case report describes a rare coexistence of a renal artery aneurysm and kidney cancer successfully treated with laparoscopic surgery.

## Contribution

The paper presents a novel surgical approach for managing a rare combination of renal artery aneurysm and renal cell carcinoma.

## Key findings

- A laparoscopic partial nephrectomy was successfully performed on a patient with a renal artery aneurysm and a kidney tumor.
- The case suggests that small, asymptomatic aneurysms may not require immediate repair if tumor removal is feasible.
- The report contributes to the limited literature on the surgical management of this rare condition.

## Abstract

Renal artery aneurysms (RAAs) represent an uncommon condition, and their coexistence with renal cell carcinoma (RCC) is exceedingly rare. The surgical management of this combination is notably complex. In cases when the renal tumor is small in size and suitable for partial nephrectomy (PN), there are ongoing debates regarding the method of pedicle control during the procedure and the necessity of concurrent aneurysm repair. This case report study details a successful PN performed laparoscopically on a 58-year-old male patient with a saccular aneurysm measuring 11 x 10.65 mm that was identified involving the segmental artery at the site of branch formation in the distal of the right renal artery and a 23 x 24 mm cystic mass in the posterior to lower pole of the kidney, along with the treatment techniques associated with this condition in relation to current literature. In cases where the aneurysm is small, asymptomatic, and permits renal artery control, as demonstrated in our case, treatment may focus solely on the renal tumor.
