Intracranial Gorgon: Surgical Case Report of a Large Calcified Brain Arteriovenous Malformation

Pediatric intracranial calcified arteriovenous malformation: A case report

Background:

Brain arteriovenous malformations (AVMs) are intracranial lesions that consist of a complex tangle of abnormal blood vessels. They can occasionally become hard and calcified. This may render these lesions difficult to resect and lead to neurological complications. There are very few reported cases of calcified brain AVMs in the literature.

Case Description:

We report the case of an 11-year-old patient who presented with headaches and seizures exacerbated in the past 3 months. Preoperative imaging confirmed a large, right parasagittal AVM, with significant internal calcifications seen on the computed tomography angiogram. We performed a successful microsurgical resection of the calcified AVM and confirmed the diagnosis on histopathological analysis.

Conclusion:

Dense internal calcifications within AVMs are a clinical rarity and can be challenging cases for microsurgical resection.
