Abstract
BACKGROUND: Neurenteric cysts (NCs) are rare, non-neoplastic lesions arising from a failure of dissolution of the transient neurenteric canal between the foregut and the notochord. They are most frecuently seen in the intradural extramedullary space in the lower cervical and upper thoracic spine. The authors describe a rare case of neurenteric cyst arising from the ventral cervicomedullary junction that was totally resected via a posterior approach.
CASE DESCRIPTION: A 24-year-old woman presented with a four week history of neck pain and progressive left hemiparesis. Admission magnetic resonance imaging (MRI) demonstrated an intradural extramedullary cystic mass lesion ventral to the upper spinal cord from medulla to C2. We performed a posterior approach and the lesion was totally removed. Surgical treatment resulted in resolution of the neurological impairments. The histological results were consistent with neurenteric cyst. Postoperative course was uneventful. At sixth month of follow-up the patient is asymptomatic and MRI shows no residual lesion.
CONCLUSION: Neurenteric cyst is a rare lesion of the craniospinal junction, and should be considered among differential diagnoses. Complete excision is the treatment of choice. In most instances a dorsal surgical approach will be satisfactory.
