    Foreign particles found in brain arteriovenous malformations (AVMs) may originate from cerebral angiography. These particles are a common pathological finding in AVMs and can be clinically significant.

    Area of Science:

    • Neuropathology
    • Vascular Surgery

    Background:

    • Arteriovenous malformations (AVMs) are complex vascular lesions requiring surgical resection.
    • Cerebral angiography is a common diagnostic procedure for evaluating AVMs.

    Observation:

    • Analysis of 84 surgically resected AVMs revealed refractile foreign particles within vessel walls in four cases.
    • Endothelial lining was observed around these foreign particles.
    • Granuloma formation was associated with the particles in three of the four cases.

    Findings:

    • The foreign particles are likely iatrogenic, introduced during cerebral angiography.
    • These particles represent a notable pathological finding, more prevalent in AVMs compared to other neurosurgical specimens.
    • The abundance of these particles may correlate with clinical significance.

    Implications:

    • Highlights a potential complication or incidental finding associated with cerebral angiography in AVM patients.
    • Suggests the need for awareness among neurosurgeons and pathologists regarding these foreign particles.
    • May influence the interpretation of AVM pathology and patient management.
