Summary
A rare case of pure sensory stroke was identified in a young woman due to a small thalamic hematoma. This finding highlights the thalamus as a potential cause of sensory deficits.
Area of Science:
- Neurology
- Neuroimaging
- Stroke Medicine
Background:
- Pure sensory stroke is a rare clinical presentation.
- Thalamic lesions are uncommon causes of stroke, particularly pure sensory deficits.
Observation:
- A 25-year-old female presented with unilateral facial, tongue, and hand numbness.
- Neurological and neuropsychological examinations were normal.
- Brain CT revealed a small right thalamic hematoma (5-7 mm).
Findings:
- The hematoma likely affected the ventroposteromedian and ventroposterolateral thalamic nuclei.
- This case represents one of the few documented instances of thalamic hematoma causing pure sensory stroke.
- Discrepancy between absent clinical signs and present symptoms is noted.
Implications:
- Thalamic hematomas should be considered in the differential diagnosis of pure sensory stroke, even in young patients.
- The specific location within the thalamus is crucial for understanding the sensory deficits.
- This case contributes to the limited literature on thalamic hematomas and their clinical manifestations.
