Stroke in Young-Dilative Arteriopathy: A Clue to Late-Onset Pompe's Disease?

Importance: In almost a third of stroke in young cases, etiology remains unclear. We report a radiological entity which might give a clue toward detection of late onset Pompe's disease in some cases.

Observation: Here we report two cases of stroke in young in which evaluation led to diagnosis of late onset Pompe's disease.

Dural arteriovenous fistula (DAVF) is an important cause of neurological dysfunction that is often misdiagnosed, especially in elderly population. Galenic DAVFs are a subtype of the rare falcotentorial DAVFs with a high risk of hemorrhage and aggressive clinical course. In most cases, DAVFs present with pulsatile tinnitus, headache, or orbital symptoms such as chemosis and proptosis.
