Abstract
Introduction: Hydatid disease is caused by Echinococcus granulosus parasite. It is an endemic disease; particularly in many Mediterranean countries. Bone involvement is reported in 1–2% of the cases and about 50% of those are seen in the spine. Herein we report a case of primary spinal extradural hydatid cyst that caused paraplegia due to compression of the dorsal spinal cord and was diagnosed initially as case of lumbar prolapsed intervertebral disc.
Case Report: A 40-year-old female referred to us suffering from painful spastic weakness of lower limbs, her condition started six months earlier to admission and she became paraplegic for last four months with loss of bladder and bowel control. She had L4, L5 lumbar laminectomy four months earlier as she was diagnosed as lumbar prolapsed intervertebral disc. After a thorough diagnostic workup, it was provisionally found that she has a malignant posterior mediastinal mass, but surprisingly only intraoperatively we discovered that she had only a posterior mediastinal hydatid cyst, which had been treated accordingly.
Conclusion: Hydatid cyst may speculate all types of thoracic tumors so high index of suspension should be considered in treating thoracic tumors in an endemic area.

Keywords: Mediastinal hydatid cyst, Neurogenic tumor, Paraplegia
