Hydatid Disease of Vertebral Column

A 30 years old male presented to us with history of back pain and weakness of both lower limbs for the last four months and was diagnosed by local orthopedic surgeon as a case of carries spine. He also used anti tuberculous drugs for two months but there was no improvement in his symptoms. We planned for transpedicular spinal biopsy. Biopsy report came to be non specific chronic inflammation. We reexamined the investigations and we found in Magnetic Resonance Imaging (MRI) soft tissue mass with multiple septaion and cyst formation nearby the vertebra. We did indirect haemagglutination test for Hydatid disease which became positive. MRI and biopsy reports were reevaluated by radiologist histopathologist respectively. Both of them confirmed the diagnosis of Hydatid cyst. In first instance we did decompression and posterior spinal fixation with pedicular screws and rods. In the next stage then we removed the L1 vertebral body and placed cage with bone graft. He was put on Albendazole 400mg twice daily for three months as advised by physician. His weakness was improved dramatically.
