Unresolved drooling in a previously healthy child caused by a brainstem malignancy

Area of Science:

• Pediatric Neurology
• Otorhinolaryngology
• Pediatric Oncology

Background:

• Drooling is common in infants but can persist beyond age two.
• Persistent drooling often leads to otorhinolaryngology (ENT) consultations.
• In absence of neurological issues, behavioral management is typically advised.

Observation:

• A case of persistent drooling presented as the initial symptom of brain stem malignancy.
• Diagnosis was aided by a sleep study revealing central apneas.
• Magnetic resonance imaging (MRI) confirmed an intra-axial brainstem tumor.

Findings:

• Persistent drooling can be an early indicator of serious underlying neurological conditions.
• Central apneas identified during sleep studies can suggest brainstem abnormalities.
• Brainstem tumors, though rare, must be considered in the differential diagnosis of persistent drooling.

Implications:

• Highlights the importance of a thorough diagnostic approach for persistent drooling in children.
• Emphasizes the necessity of a multidisciplinary team (MDT) approach for complex pediatric cases.
• Underscores the need to consider serious pathologies beyond typical developmental causes for persistent drooling.
