[Lateral semicircular canal cupulolithiasis in children: a case report]

Area of Science:

• Otolaryngology
• Neurology
• Vestibular System Disorders

Background:

• Benign paroxysmal positional vertigo (BPPV) is a common inner ear disorder.
• Lateral semicircular canal cupulolithiasis is a specific subtype of BPPV.
• Pediatric BPPV cases are less common, making pediatric presentations noteworthy.

Observation:

• A 12-year-old child presented with acute onset vertigo and nausea.
• The roll test revealed strong apogeotropic nystagmus in the left recumbent position.
• This nystagmus pattern indicated right lateral semicircular canal cupulolithiasis.

Findings:

• The diagnosis of right lateral semicircular canal cupulolithiasis was confirmed.
• Li's quick repositioning maneuver was administered as treatment.
• Complete resolution of vertigo and nausea was achieved post-maneuver.

Implications:

• This case highlights the efficacy of Li's quick repositioning maneuver in pediatric lateral canal BPPV.
• Early diagnosis and prompt treatment are crucial for managing pediatric vestibular disorders.
• The successful outcome suggests this maneuver is a safe and effective option for children.
