Case in brief
A 13-year-old boy presented with acute-onset generalized dystonia, characterized by progressive slowness, speech loss, dysphagia, rigidity, and dystonic posturing over a month. Despite extensive evaluations, including CSF analysis and brain MRI, no definitive cause was identified. Treatment with corticosteroids and antivirals was ineffective. The patient underwent deep brain stimulation, which yielded limited functional improvement, highlighting the need for genetic testing in similar cases.
What made this case unusual
The case's unique aspect was the rostrocaudal severity distribution of dystonia and significant bulbar dysfunction, which guided the diagnostic process away from typical acquired encephalitis.
Diagnostic / clinical pearl
Clinicians should consider early genetic testing in cases of dystonia with rostrocaudal severity distribution and bulbar involvement, as these features may indicate underlying genetic disorders.
Why it matters
This case emphasizes the importance of recognizing atypical clinical presentations that can shift the focus from common acquired conditions to genetic etiologies, potentially leading to more accurate diagnoses.
