Chiari Type I malformation (CM-I) is a rare disorder with displaced cerebellar tonsils through foramen magnum. Here we present a 30-year-old man with severe central and obstructive sleep apneas as presenting manifestations of CM-I. The patient underwent neurosurgery and the follow-up polysomnography revealed the resolution of central apnea while obstructive apnea remained unchanged. Central sleep apnea (CSA) could be associated with an underlying pathology; thus, further investigation is recommended in affected subjects.
