Multiple intradural spinal hydatid disease: a case report and review of literature.

Study Design: A case report.

Objective: We present an unusual case of pathologically confirmed multiple distinct spinal intradural extramedullar spinal hydatid cyst after 1 year of lung cyst hydatid operation.

Summary Of Background Data: Hydatid disease is usually diagnosed in endemic regions. Spinal involvement of disease is very unusual and the literature about this entity is generally restricted to regional publications. Furthermore, intradural multiple involvement was not reported in literature.

Methods: A 14-year-old boy admitted to our clinic with pain in the back, both of leg and disability in walking. The patient presented with back pain, asymmetrical paraparesis, right more than left and weakness. Multiple distinct spinal intradural extramedullary cystic lesion was identified with magnetic resonance imaging and was shown to be hydatid cyst by histopathologic confirmation after the surgical removal.

Results: T5 and L4, L5, S1 laminectomies were performed at the same session, after these a lot of pearly white hydatid cysts located intradural extramedullary were removed totally with their capsule, and the cavity was irrigated with 20% hypertonic saline. Surgical treatment was uneventful. Second-month follow-up neurologic examination was normal and the hydatid cysts had totally disappeared in both regions in the second month of postoperative magnetic resonance imaging.

Conclusion: Spinal hydatid disease are uncommon. Among these, multiple distinct spinal intradural extramedullar location is extremely rare. Although total removal of the cysts without rupture should be the surgical goal in all cases, the best treatment remains an active nationwide prevention of the disease.
