## TL;DR

A 38-year-old man was found to have an extra right kidney, highlighting the need for thorough imaging to avoid unnecessary procedures.

## Contribution

This case report adds to the limited medical literature on supernumerary kidneys and their clinical implications.

## Key findings

- The patient had a right supernumerary kidney with its own vascular and collecting systems.
- The discovery of the extra kidney altered the management plan and prevented unnecessary interventions.

## Abstract

Supernumerary kidney is a highly uncommon congenital anomaly characterized by the presence of at least 1 or more extra kidneys in variable positions and morphology. Due to the scarcity in the medical literature, not much is known about this condition. The additional kidney typically has its own collecting system, vascular supply, and distinct encapsulated parenchyma. In this case, we present a 38-year-old male with a right supernumerary kidney who was initially investigated for a renal artery aneurysm. In the case of our patient, the discovery of a supernumerary kidney influenced the course of management and prevented unnecessary intervention and procedure. This emphasizes the importance of thorough imaging and diagnostic techniques in patients to accurately identify and characterize such anomalies.
