AB  - Osteopetrosis is a rare genetic disorder resulting in increased bone density and decreased bone remodelling. Bone expansion results in the crowding of neural foramina causing cranial nerve compression. Here, we describe a female infant in her mid infancy presented with no eye contact since birth, and abdominal distension for 2 months. On CT evaluation, sclerotic bones with bilateral optic canal narrowing were present. A crowded posterior fossa with Arnold Chiari type I malformation was seen on MRI evaluation, suggesting a rare association of osteopetrosis with Arnold Chiari’s malformation.
