Summary
The artery of Percheron, a rare variant, can cause bilateral thalamic infarction if occluded. This case highlights its complex symptoms and the importance of MRI for diagnosis.
Area of Science:
- Neuroscience
- Vascular Neurology
- Neuroimaging
Background:
- The human thalami receive blood supply from a complex network of arteries with significant variations.
- The artery of Percheron is a rare anatomical variant, supplying the paramedian thalami via a single trunk originating from the posterior cerebral artery.
Observation:
- This report details a case of bithalamic infarction resulting from the occlusion of the artery of Percheron.
- The patient presented with complex clinical symptomatology indicative of bilateral thalamic and potential midbrain involvement.
Findings:
- Occlusion of the artery of Percheron can lead to bilateral paramedian thalamic infarction.
- Imaging, particularly Magnetic Resonance Imaging (MRI), is crucial for diagnosing this condition and its extent.
Implications:
- Understanding the artery of Percheron variant is essential for neurologists and radiologists.
- Prompt diagnosis through advanced neuroimaging can guide management strategies for thalamic infarction.
