A rare case of head injury associated with Albers Schonberg disease

Albers Schonberg disease commonly called as osteopetrosis is a disorder involving defective bone resorption. The severe autosomal recessive form of osteopetrosis is very rare and characterised by abnormalities in skeletal bones, delayed psychomotor development, optic and facial nerve dysfunction, hydrocephalus, anaemia, haematologic and bleeding disorder, and a diversity of other manifestation. We report a case of intracranial subdural haematoma following a trivial head injury in an infant with severe autosomal recessive form of osteopetrosis.
