Neuroenteric cysts of the brain-comprehensive magnetic resonance imaging
A 17-year-old female patient presented with occasional headache since two years increased since the last three months. On examination, bilateral papilledema was present. No other focal neurological deficits were present.\nMRI [] showed a well-defined CSF-intensity cystic lesion in the region of the fourth ventricle with obstructive hydrocephalus. There were no enhancing solid components. The lesion showed facilitated diffusion. The patient underwent midline suboccipital craniotomy and deroofing of the cyst. Histopathology showed cuboidal or columnar epithelium (pseudostratified at some foci). Based on the immunohistochemical properties, a final diagnosis of neuroenteric cyst was made. Patient did well in the post-operative period with reduction of the hydrocephalus.
