Summary
A lacunar stroke in the internal capsule caused severe hypertension, leading to leg weakness and balance issues. This finding highlights the neurological impact of uncontrolled high blood pressure.
Area of Science:
- Neurology
- Neuroimaging
- Vascular Neurology
Background:
- Severe hypertension is a significant risk factor for cerebrovascular events.
- Lacunar strokes often result from small vessel disease, commonly associated with hypertension.
Observation:
- A 61-year-old male patient presented with acute onset of crural paresis and ipsilateral ataxia.
- Clinical presentation suggested a focal neurological deficit in the motor and sensory pathways.
Findings:
- Computed Tomography (CT) scan revealed a hypodense lesion in the posterior limb of the internal capsule.
- The imaging finding is consistent with a lacunar infarct, a small ischemic stroke.
Implications:
- This case underscores the potential for severe hypertension to precipitate lacunar strokes.
- Understanding the localization of lacunar infarcts is crucial for diagnosing and managing neurological deficits.
- Early recognition and management of hypertension can prevent such debilitating neurological events.
