Objective: We encountered a patient with lateral medullary infarction during transarterial embolization of the posterior meningeal artery (PMA). We reviewed the anatomic characteristics/imaging findings of this disorder.
Case Presentation: A 69-year-old male. Cerebral infarction involving the lateral medulla occurred during transarterial embolization of a dural arteriovenous fistula. It was considered to be a complication related to occlusion of a lateral medulla-penetrating vessel on microcatheter/guidewire operations in the PMA. When examining images in detail, the blood vessel could be confirmed using DSA and 3D angiography.
Conclusion: When performing embolization, the presence of a brainstem-penetrating vessel originating from the PMA must be considered.
