Giant mesencephalothalamic virchow-robin spaces causing obstructive hydrocephalus. A case report.

Virchow-Robin spaces accompany arteries for a variable distance into the brain substance. They are usually small but can be identified on high resolution MRI images in patients of all age groups. We report a rare case of a 40-year-old woman with giant mesencephalothalamic Virchow-Robin spaces which caused hydrocephalus requiring CSF diversion. After right ventriculoperitoneal shunt the patient recovered completely.
