Transient cerebellopontine demyelinisation revealed by MRI in acute cerebellar ataxia

Abstract:
An eight year old boy was admitted to our ward with a history of abrupt onset of rapidly progressive gait disorder, nausea, vertigo and vomiting. The clinical as well as the laboratory findings suggested the diagnosis of acute cerebellar ataxia. Magnetic resonance imaging (MRI), however, showed marked demyelinisation in the cerebellar region and visual evoked potentials were pathologic. After immunosuppression the patient promptly improved clinically and the lesions depicted by MRI disappeared almost completely.
Insights
A child with acute cerebellar ataxia showed demyelination on MRI. Immunosuppression led to rapid clinical improvement and lesion resolution, suggesting an inflammatory or autoimmune process.
Area of Science:
- Pediatric Neurology
- Neuroimmunology
- Neuroradiology
Background:
- Acute cerebellar ataxia (ACA) is a common cause of gait disturbance in children.
- Demyelinating lesions in ACA can indicate various underlying etiologies, including autoimmune conditions.
Observation:
- An 8-year-old boy experienced sudden onset of gait disorder, nausea, vertigo, and vomiting.
- Clinical and laboratory findings initially suggested ACA.
- Magnetic resonance imaging (MRI) revealed significant cerebellar demyelination, and visual evoked potentials were abnormal.
Findings:
- The patient underwent immunosuppressive therapy.
- Following treatment, there was prompt clinical improvement.
- MRI scans showed near-complete resolution of the cerebellar lesions.
Implications:
- This case highlights the importance of considering demyelinating disorders in the differential diagnosis of ACA.
- Prompt diagnosis and immunosuppressive treatment can lead to favorable outcomes in pediatric demyelinating cerebellar ataxia.
- Neuroimaging and electrophysiological studies are crucial for identifying demyelination in acute neurological presentations.
