A case of hemeplegic migraine with leptomeningeal angiomatosis.

A 43 year old man with thirty years history of recurrent hemiplegic migraine, consistently occurring on one side (left sided paresthesia and weakness of less than forty five minutes followed by right sided headache) and lately increasing to once in three days was investigated. CT head and carotid angiogram showed gyral calcification with prominent medullary and subependymal veins confirming the diagnosis of leptomeningeal angiomatosis. Management and followup is discussed.
