Chiari Malformation and sleep-disordered breathing : A review of diagnostic and management issues

Chiari Malformation (CM) encompasses several patterns of congenital or acquired cerebellar herniation through the foramen magnum. This may result in brain-stem compression that impacts control of breathing and is associated with obstructive and central apneas. A high clinical suspicion for sleep-dis...

Description
Summary:Chiari Malformation (CM) encompasses several patterns of congenital or acquired cerebellar herniation through the foramen magnum. This may result in brain-stem compression that impacts control of breathing and is associated with obstructive and central apneas. A high clinical suspicion for sleep-disordered breathing is needed in the care of such patients after as well as before corrective surgery. To introduce a review of CM with a focus on the relevance to sleep medicine, we present a case of a 13-year-old female who was diagnosed with CM Type 1 in the course of an evaluation of symptomatic central sleep apnea. After initial improvement following surgery there was recurrence of brain-stem compression. The only clinical expression of which was polysomnographically evident recurrence of sleep apnea.
