Abstract
Sleep-disordered breathing, with both central and obstructive sleep apneas, has been reported in association with Chiari malformation type 1. Chiari malformation type 1 is a congenital or acquired herniation of the cerebellar tonsils through the foramen magnum. In this case, a 5-year-old girl with a history of Chiari malformation type 1 and syringomyelia experienced worsening intracranial pressure secondary to sleep-disordered breathing. This case highlights the importance of early recognition of sleep-related respiratory disorders in patients with Chiari malformation and its association with increased intracranial pressure.
