Summary
Lacunar CCT lesions have a debated cause. This case suggests emboli or hemodynamic changes from internal carotid artery occlusion may cause these small brain lesions.
Area of Science:
- Neurology
- Vascular Neurology
- Neuroimaging
Background:
- Lacunar CCT lesions are small infarcts in the brain's deep structures.
- Their exact cause, particularly whether they are embolic or hemodynamic, remains debated.
Observation:
- A patient presented with recurrent ischemia in the right internal carotid artery territory.
- Initial computed tomography CCT revealed a non-lacunar lesion in the basal ganglia and internal capsule.
- A subsequent CCT demonstrated a singular lacunar defect in the internal capsule.
Findings:
- Doppler sonography confirmed an internal carotid artery occlusion.
- The development of a lacunar lesion after initial non-lacunar changes suggests a dynamic process.
Implications:
- This case supports the hypothesis that embolic or hemodynamic factors contribute to lacunar lesion formation.
- Understanding the etiology of lacunar lesions is crucial for stroke prevention and treatment strategies.
