Summary
We report a rare case of a hyperplastic anterior choroidal artery with two persistent anastomotic channels, including an unusual secondary channel. This finding offers new insights into cerebral artery variations.
Area of Science:
- Neurology
- Vascular Anatomy
- Medical Imaging
Background:
- The anterior choroidal artery (AChA) is a critical cerebral vessel supplying key brain structures.
- Variations in AChA anatomy, though uncommon, can have significant clinical implications.
Observation:
- A case of a hyperplastic AChA was identified during vertebral angiography.
- The anomaly presented with a unique, secondary persistent anastomotic channel alongside a primary one.
Findings:
- The identified hyperplastic AChA demonstrates an unusual anatomical configuration with double persistent anastomotic channels.
- This specific morphology differs from previously documented variations of the AChA.
Implications:
- This case expands the known spectrum of anterior choroidal artery anatomical variations.
- Understanding such anomalies is crucial for accurate neurovascular diagnosis and surgical planning.
