Spinal hydatid disease: A case report

Abstract

Introduction: The parasitic tapeworm Echinococcus granulosus causes cystic echinococcosis, also known as hydatidosis. It is a serious medical condition that can show up in a lot of different ways. Although spinal involvement occurs in about 45% of bone echinococcosis cases, it represents only 0.5–4% of all echinococcosis cases. The disease can spread to the spine through hematogenous dissemination, direct invasion, or cerebrospinal fluid seeding from ruptured cysts. While the liver and lungs are the most commonly affected organs, spinal involvement can lead to severe complications, including radiculopathy, motor deficits, and paraparesis. Imaging, such as computed tomography (CT) and (MRI), typically makes the diagnosis by revealing cystic and osteolytic lesions. Case Report: The patient is a 51-year-old male from the Kakheti region (a region in Georgia) who presented with progressive generalized weakness, nausea, vomiting, and lumbar pain. He had a history of spinal echinococcosis, diagnosed 15 years ago, but was unable to complete antiprotozoal treatment due to intolerance to albendazole. Over the years, his condition deteriorated, leading to lower paraplegia and urinary incontinence, necessitating a suprapubic cystostomy. Imaging revealed extensive septated cystic lesions in Th4-S1, which spread to the ribs and subcutaneous tissues. Despite neurosurgical intervention to reduce the cyst burden, the infestation persisted. Multiple hospitalizations were required for complications, such as urinary tract infections and pneumonia. Joint supervision managed the patient’s condition, but he continued to experience spherocyte discharge from numerous fistulas. Conclusion: This case underscores the severe and chronic nature of spinal echinococcal infection, particularly when complete antiprotozoal treatment is not feasible. The patient did not experience severe neurological complications despite the extensive disease burden and the development of multiple vertebral-cutaneous fistulas, possibly due to the continuous drainage of spherocytes. This unusual clinical course highlights the importance of comprehensive management and the potential impact of innovative approaches on managing complex parasitic infections.
