Insights
Pediatric sleep-disordered breathing can stem from central causes, not just obstructive ones. This case highlights the importance of considering Chiari malformation in diagnosing apnea in children.
Area of Science:
- Pediatric Neurology
- Sleep Medicine
- Neurodevelopmental Disorders
Background:
- Sleep-disordered breathing (SDB) is a common concern in children, often attributed to upper airway obstruction.
- Enlarged adenoids are a frequent cause of obstructive sleep apnea (OSA) in pediatric patients.
- This case examines an unusual presentation of SDB initially suspected as OSA.
Observation:
- A 4-year-old girl presented with significant sleep-disordered breathing, characterized by prolonged pauses and daytime fatigue.
- Initial treatment targeting obstructive causes (adenotomy) failed to resolve the symptoms.
- Polysomnography revealed central apneas, prompting further investigation.
Findings:
- Central apneas were identified as the primary cause of SDB, despite initial suspicion of obstructive apnea.
- Cerebral magnetic resonance imaging (MRI) diagnosed a Chiari type I malformation.
- Polysomnography proved crucial in differentiating central from obstructive apneas.
Implications:
- This case underscores the necessity of considering central causes of apnea in children, even without overt neurological symptoms.
- It emphasizes the diagnostic value of polysomnography in distinguishing between central and obstructive sleep apnea.
- Early identification of underlying neurological conditions like Chiari malformation is vital for effective management of pediatric SDB.
Unlabelled:
A 4-year-old girl presented with sleep-disordered breathing. Her parents described breathing pauses of up to 20 s and progressive tiredness during the day. Obstructive apneas from an enlarged adenoid were thought to be the most probable cause. However, an adenotomy did not resolve the problem. Polysomnography demonstrated central apneas, and cerebral magnetic resonance imaging revealed a Chiari type I malformation. We describe the differential diagnosis of apnea in children and the role of polysomnography in the distinction between obstructive and central apneas.
Conclusion:
This case illustrates that, in children with apnea, it is important to consider central causes as well as the more common obstructive causes, even in the absence of additional neurological signs or symptoms.
