Aim: Hydatid disease is caused by infestation with Echinococcus granulosus. Lung and liver are by far the most common regions affected. Spinal hydatid disease is a rarity, even more so in children. Although the disease of primary vertebral origin is rare, it has devastating sequelae. Therefore, clinicians working in endemic areas should consider it in the differential diagnosis.

Method: A 9-year-old female child suffered from a 1-month history of back pain after a traumatic fall while walking. Disability in walking and progressive weakness and numbness of both lower extremities were her accompanied other symptoms. The initial clinical examination on the admission of our hospital revealed muscle strength is 3-4/5 in the lower extremity, and there is hypoesthesia starting from bilateral L1 dermatome on sensory examination. In spinal MRI, a lesion measuring 19x13x0.9 cm in the posterior part of the T12 vertebral body, hypointense in T1AG and hyperintense in STIR sequence is detected. An operation was carried out, T12 total laminectomy; T11-L1 partial total laminectomy was performed, and cyst hydatid like lesion was removed totally by preserving cyst wall integrity and taking care of unrupturing in stepwise water dissection method. Pathology report was compatible with hydatid cyst. She used albendazole for 6 months. The patient presented again with complaints of back pain and gait disturbance after 3 years of follow-up. A newly developed cystic lesion was detected in spinal MRI. He was operated on and L1 Total laminectomy and T11 laminectomy expansion were performed. Albendazole treatment was discontinued at 1 year with control imaging. In the follow-up, 2 years later, the patient’s control spinal MRI showed an increase in the size of the cystic component extending to the spinal cord compared to the previous examination, and increased pressure on the canal and conus. He was operated, T10-11 and L1-2 stabilization, total excision of the left paracentral extradural lesion compatible with hydatid cyst was performed from the T12 level. He was followed up for 2 years with albendazole.

Results: Cabergoline and baclofen treatment was started for the muscle spasms of the patient whose lordosis became evident to compensate for postoperative kyphosis and pain. He is being followed under exercise with the physical therapy and rehabilitation department.
