# Recurrent renal hydatid disease with suspected pelvic seeding: a case report

## TL;DR

A man with a history of kidney hydatid disease experienced a recurrence, highlighting the need for long-term monitoring and careful management.

## Contribution

This case report presents a rare recurrence of renal hydatid disease with possible pelvic seeding.

## Key findings

- The patient had two prior surgeries for right renal hydatid cysts and presented with recurrent symptoms.
- Laparoscopic treatment and albendazole therapy led to successful recovery with no recurrence.
- The case emphasizes the importance of surveillance and multimodal imaging in managing hydatid disease.

## Abstract

Renal hydatid disease is a rare manifestation of echinococcosis, accounting for ˂4% of cases. We report a 47-year-old male with two prior surgeries for right renal hydatid cysts, presenting with right upper quadrant pain, dysuria, and low-grade fever. Imaging revealed a recurrent right renal cystic lesion and an incidental pelvic cyst near the seminal vesicle, raising concern for possible dissemination. Laparoscopic aspiration and deroofing of the renal cyst were performed, followed by a 6-month course of albendazole. Recovery was uneventful, and follow-up imaging showed no recurrence or new cyst formation. This case highlights the importance of long-term surveillance in renal hydatid disease and the need to consider rare sites of recurrence or dissemination. Multimodal imaging and minimally invasive surgery play a central role in diagnosis and management, even in patients outside endemic regions.
