Summary
This case report details a rare instance of isolated bilateral middle cerebellar peduncle infarction in a patient with severe vertebrobasilar disease, suggesting hypoperfusion as a likely cause.
Area of Science:
- Neurology
- Cerebrovascular Diseases
- Neuroimaging
Background:
- Vertebrobasilar disease poses a significant risk for ischemic stroke.
- Middle cerebellar peduncle (MCP) infarction is an uncommon stroke subtype.
Observation:
- A patient with known severe vertebrobasilar disease presented with acute neurological deficits.
- Neuroimaging revealed isolated infarction exclusively affecting the bilateral middle cerebellar peduncles.
Findings:
- Isolated infarction of the middle cerebellar peduncle (MCP) occurs in approximately 0.12% of acute strokes.
- The simultaneous bilateral MCP infarction is exceptionally rare, with few documented cases.
- The MCP's location as a watershed zone between the anterior inferior cerebellar artery and superior cerebellar artery territories suggests a hypoperfusion etiology.
Implications:
- This case highlights the potential for isolated bilateral MCP infarction in patients with severe vertebrobasilar disease.
- Understanding rare stroke patterns is crucial for accurate diagnosis and management.
- Further research into the specific mechanisms of MCP hypoperfusion is warranted.
