Dystonia as a presenting sign of subacute necrotising encephalomyelopathy in infancy
Abstract:
A case of subacute necrotising encephalomyelopathy is reported with such note worthy features as early onset, dystonic manifestations and the presence of low attenuation areas in the basal ganglia on computerised tomography of the brain. Laboratory findings were normal and the diagnosis was confirmed at postmortem examination.
Insights
This case report details subacute necrotising encephalomyelopathy (SNE) in a patient with early-onset dystonic symptoms. Postmortem examination confirmed the diagnosis, highlighting SNE
Area of Science:
- Neurology
- Pathology
Background:
- Subacute necrotising encephalomyelopathy (SNE), also known as Leigh syndrome, is a rare mitochondrial disease.
- It typically affects infants and young children, presenting with progressive neurological deterioration.
Observation:
- This report describes an unusual case of SNE with an early onset.
- Notable clinical features included dystonic manifestations.
- Computerised tomography (CT) revealed low attenuation areas in the basal ganglia.
Findings:
- Laboratory investigations were within normal limits, complicating early diagnosis.
- The diagnosis of SNE was definitively confirmed through postmortem examination.
- The case highlights atypical presentations of SNE, including early onset and specific CT findings.
Implications:
- This case expands the understanding of the clinical and radiological spectrum of subacute necrotising encephalomyelopathy.
- Early recognition of atypical features is crucial for timely diagnosis and management, despite normal lab results.
- Further research into mitochondrial diseases and their varied presentations is warranted.
