[Hypoplasia of the internal carotid artery: a rare cause of cerebral ischemic stroke in children].

Hypoplasia of the carotid arteries is a rare congenital anomaly which, when symptomatic, presents as cerebral ischemia or hemorrhage. We report a case of hypoplasia of the carotid arteries revealed by cerebral ischemic stroke in an infant with hereditary spherocytosis. The diagnosis was confirmed by MR angiography. We describe this rare cause of stroke in children and the characteristics of its association with hereditary spherocytosis.
