Eight-year-old with delayed motor milestones and falls

Vignette

An eight-year-old girl is referred by her paediatrician for evaluation of unsteadiness, falls on uneven surfaces, and difficulty riding a bicycle. She had bacterial meningitis at 18 months of age. Her parents report that she walks unsteadily in the dark and clings to the railing on stairs. Examination shows a positive Romberg test, bilateral abnormal head impulse responses, and a wide-based gait. Audiometry shows severe bilateral sensorineural hearing loss. Caloric testing is technically challenging but shows bilaterally reduced responses. CDP can be performed in age-appropriate equipment.

Bacterial meningitis is a classical cause of combined bilateral vestibulopathy and severe bilateral sensorineural hearing loss — both labyrinths are damaged by the same inflammatory or ischaemic process. The audiogram and CDP each document a severe deficit; together they argue for aggressive audiological habilitation (cochlear implantation candidacy) alongside vestibular rehabilitation.

Given the clinical picture and CDP findings, what is the most likely diagnosis and the most appropriate management priority?

Teaching point. Bacterial meningitis is a recognised cause of paediatric bilateral vestibulopathy, often producing concomitant severe sensorineural hearing loss. The CDP pattern in children mirrors that in adults — severe C5/C6 reduction with falls — but rehabilitation is more effective because of greater plasticity. Early intervention with audiological habilitation and vestibular rehabilitation can substantially improve outcomes.
