title: Spontaneous hemorrhage into a neurenteric cyst of the cerebellar vermis.
abstract: Neurenteric cysts are rare benign developmental lesions of the central nervous system which are lined by endodermal cell-derived epithelium. Here we present a 17-year-old male who presented with acute onset headache and cerebellar ataxia. He was found to have a hyperdense lesion of the cerebellar vermis on CT scan. The lesion was hyperintense on T₁-weighted and hypointense on T₂-weighted MR images. Surgical resection of the cyst revealed hemorrhage into the neurenteric cyst.
