Middle cerebral arterial occlusion in a child with osteopetrosis major.

Osteopetrosis major (infantile autosomal recessive type) usually presents with pathological fractures, bone marrow failure and some neurological deficits due to remodelling defect of the bone and narrowed bonny channel of the blood supply. Herein we present a case of osteopetrosis major with neurological deficits not attributed to the narrowed carotid channel of the petrous bone, but due to middle cerebral arterial occlusion 2 cm distal to narrowed channel.
