Hydatid disease, caused by Echinococcus granulosus, predominantly affects the liver and lungs, while musculoskeletal involvement is rare. Osseous hydatidosis involving the pelvis presents considerable diagnostic and therapeutic challenges owing to its infiltrative nature, proximity to vital neurovascular structures, and high risk of recurrence. We report a rare case of recurrent pelvic hydatid disease with extensive involvement of the left ilium, sacrum, iliopsoas, and gluteal musculature.

A 25-year-old female presented with a progressively enlarging swelling in the left lower abdominal quadrant for four months. She had undergone surgical excision of a similar lesion three years earlier and remained asymptomatic until the current presentation. Radiographic evaluation, computed tomography, and magnetic resonance imaging demonstrated extensive osteolytic and multiloculated cystic lesions involving the left iliac bone, with extension into the surrounding soft tissues. Considering the extensive disease and its proximity to critical neurovascular structures, a multidisciplinary team comprising orthopedic, surgical gastroenterology, and plastic surgery specialists planned definitive surgical management. The patient underwent extensive excision of the involved tissues with type I left hemipelvectomy, followed by irrigation with scolicidal agents and postoperative albendazole therapy for six months. Postoperative recovery was satisfactory, although transient sensory disturbance and hip abductor weakness resulted in an abductor lurch. Structured rehabilitation and gait training facilitated progressive functional recovery. At three months, the patient could ambulate independently, squat, and sit cross-legged comfortably.

This case highlights the importance of early recognition, meticulous surgical planning, and multidisciplinary management in extensive pelvic hydatid disease. Although radical resection may improve disease clearance, postoperative functional deficits require comprehensive rehabilitation. Prolonged antiparasitic therapy and vigilant follow-up are essential considerations in managing this rare and challenging condition.
