Primitive pelvic bone hydatidosis: What an amazing extension

Area of Science:

• Medical Parasitology
• Orthopedic Surgery
• Radiology

Background:

• Hydatidosis is a parasitic anthropozoonosis, typically affecting visceral organs like the liver and lungs.
• Skeletal hydatidosis is uncommon and usually secondary to visceral disease.
• Primary bone hydatidosis without apparent visceral involvement presents diagnostic challenges.

Observation:

• A 49-year-old male presented with a year of progressive left hip pain and limited range of motion.
• Radiographic imaging revealed extensive bone destruction of the left hemi-pelvis with multiple cystic lesions extending into the gluteal region.
• Hydatid serology was positive, and further investigations confirmed the absence of visceral hydatidosis, establishing a diagnosis of primary bone hydatid disease.

Findings:

• The case demonstrates a rare instance of primary skeletal hydatidosis.
• Diagnostic imaging, including MRI, was crucial in characterizing the extensive cystic bone lesions.
• Despite extensive involvement precluding surgical excision, medical management with Albendazole was initiated.

Implications:

• Echinococcosis should be considered in the differential diagnosis of expansive bone lesions, particularly in endemic regions.
• Early diagnosis and appropriate management are crucial for skeletal hydatidosis.
• Surgical intervention for extensive bone hydatidosis poses significant challenges, emphasizing the role of medical therapy.
