Spinal Cord Compression Resulted from Hydatid Disease: A Brief Clinical Repot and Literature Review

Hydatid disease is an infectious disease caused by echinococcus granulosus which mainly caused liver and lungs damaged in humans. Bone involvement is rare and accounts for only 0.5%-4% in hydatid disease, spine is more prone to be infected with a proportion of 50% in musculoskeletal tissue. We present a case of spinal hydatidosis in a 47‑year‑old male presenting with low back pain radiating to the legs, progressive weakness and hypaesthesia in the lower limbs accompanied with difficulty walking. Computed tomography (CT) images showed a spinal hydatid cyst in lumbar vertebra2 and caused bone destruction of the vertebral body and lamina. Magnetic resonance imaging (MRI) images showed hyperintense cystic components on lumbar vertebra2 with the appearance of a lobulated, multiocular, septated cystic mass and compressing of the spinal cord at segments lumbar vertebra1-2. The patient underwent subtotal vertebral resection to completely remove the damaged vertebral and paravertebral cysts, and histopathological examination showed the characteristic features of hydatid cysts. The patient received antiparasitic drugs treatment post-operation. The surgical removement combined with antiviral drugs is an effective way to treat spinal hydatidosis.
