# Isolated renal hydatid cyst: A rare presentation of echinococcosis

## TL;DR

A rare case of a kidney hydatid cyst is successfully treated with surgery and medication, emphasizing the importance of early diagnosis and imaging.

## Contribution

This case study presents a successful treatment approach for isolated renal hydatid cysts using nephron-sparing surgery and medical therapy.

## Key findings

- Imaging confirmed a large multivesicular renal hydatid cyst in a 40-year-old male.
- Nephron-sparing open cystectomy combined with preoperative albendazole effectively managed the cyst while preserving kidney function.
- Early diagnosis and surgical intervention are critical for favorable outcomes in renal hydatid disease.

## Abstract

Isolated renal hydatid cysts are rare manifestations of cystic echinococcosis and often pose diagnostic and therapeutic challenges. We present a 40-year-old male with a large multivesicular cyst in the left kidney managed successfully with preoperative albendazole followed by nephron-sparing open cystectomy. Imaging revealed typical features, and histopathology confirmed Echinococcus granulosus. Surgical precautions minimized intraoperative spillage. This case highlights the importance of imaging in diagnosis and planning, and supports open nephron-sparing surgery with medical therapy as an effective approach for managing large renal hydatid cysts while preserving renal function.

•Renal hydatid disease is rare, with isolated cases presenting diagnostic challenges.•Imaging revealed a complex cyst in the left kidney, confirming the diagnosis.•The patient underwent successful nephron-sparing surgery with cyst excision.•Early diagnosis and surgical intervention ensure favorable outcomes in renal hydatid disease.

Renal hydatid disease is rare, with isolated cases presenting diagnostic challenges.

Imaging revealed a complex cyst in the left kidney, confirming the diagnosis.

The patient underwent successful nephron-sparing surgery with cyst excision.

Early diagnosis and surgical intervention ensure favorable outcomes in renal hydatid disease.
