CASE REPORT
Uma variedade de lesões císticas pode se desenvolver no canal espinhal. Os cistos neuroentéricos são malformações do desenvolvimento, provavelmente, decorrentes da falência da separação do endoderma do ectoderma durante a embriogênese. Estes cistos são raros e representam 0,3 a 1,3% dos tumores do canal espinhal. Os autores relatam o caso de uma paciente de 38 anos com história de dor lombar há 8 meses e ressonância magnética evidenciando uma lesão cística intradural extramedular em L1-L2. A paciente foi submetida a microcirurgia com ressecção total da lesão sem sequelas pós-operatórias. A histopatologia e imuno-histoquímica confirmaram o diagnóstico de cisto neuroentérico.
A variety of cystic lesions may develop in spinal canal. Among developmental malformations, neurenteric cysts are thought to arise due to a failure of the primitive endoderm from ectoderm separation. Neurenteric cysts are rare, and account for 0,3-1,3% of all spinal cord tumors. The authors report the case of a 38-year-old female presented with an 8-month history of low back pain. A lumbar magnetic resonance imaging showed a cystic intradural extramedullary located at level L1-L2. A total microsurgery excision was performed without complication. The histopathological and immunohistochemical assays confirmed the diagnosis of neurenteric cyst.
