# Giant Renal Parapelvic Cyst: A Diagnostic Conundrum

## TL;DR

This paper presents a rare case of a giant kidney cyst successfully treated with surgery.

## Contribution

The novelty lies in reporting one of the largest parapelvic cysts ever documented in medical literature.

## Key findings

- A giant parapelvic cyst was successfully managed with open drainage and excision.
- The case highlights the rarity of such large renal cysts in clinical practice.

## Abstract

Renal cysts are the most common lesions of the kidney and affect a significant proportion of all individuals undergoing renal imaging. They can be unilateral/bilateral, focal/multifocal, or acquired/congenital. Parapelvic cysts, a subset of renal cysts, are uncommonly encountered in clinical practice. Parapelvic cysts progressing in size to involve almost the entire abdomen are even rarer. Here, we report a case of a giant parapelvic cyst in a middle-aged Asian gentleman, which was managed successfully with open drainage and excision, and is one of the largest parapelvic cysts ever reported in the medical literature.
