Sleep related breathing disorder associated with Arnold Chiari malformation type I: a case report

Introduction: Arnold Chiari malformation type I (CM-I) is an extremely rare congenital disorder with a mere incidence 0,1 to 0,5%. Type 1 Chiari malformation was defined as elongation of the cerebellar tonsils (> 6 mm) below the foramen magnum. Mixed sleep related breathing disorder (SRDB) is an exceedingly uncommon CM-I complication with a prevalence of merely 8-10%. Central sleep apnea might be caused by dysfunction of the respiratory center, whilst hypopneas could be caused by compression of pontomedullary nuclei resulted in impairment of the pharyngeal and laryngeal muscle.
