Magnetic resonance imaging (MRI) and intraoperative findings of a patient with delayed hematoma after radiosurgery for AVM

Caption

MRI scans revealed a large, contrast-enhancing cystic lesion. Intraoperative examination identified an angiomatous nodule within the cyst wall, later confirmed to be the source of ongoing hemorrhage. This finding supports a pathological link between radiation-induced cyst formation and chronic encapsulated expanding hematoma (CEEH).
