Transcranial endoscopic treatment of thalamic neuroepithelial cyst: case report and review of the literature

Thalamic neuroepithelial cysts are rare, benign lesions. Thirteen cases have been published in eight articles. The most frequent symptoms are headache, hemiparesis, tremor and related signs of hydrocephalus such as gait disturbance, confusion, and Paranaud's syndrome. Surgical interventions include endoscopic fenestration, open surgery and stereotaxic biopsy or aspiration. We report a case of a 63-year-old woman who had headache and right hemiparesis for 1 week, but no hydrocephalus. We treated her with transcranial neuronavigation-guided endoscopic complete resection. The patient recovered completely after cyst removal.
