Abstract
We reviewed the clinical presentation, imaging and histopathologic findings in 4 patients with the diagnosis of arteriovenous malformation associated with glioma that were operated on from 1991 to 2000 in our institution. Four patients (2 males; age between 15 and 52 years) presented with progressive headache with clinical evidence of intracranial hypertension (in 3) and partial seizures (in 1). CT scan showed a brain tumor without any detectable pathologic vessels. Histologic examination revealed astrocytic tumors associated with arteriovenous malformation. No patient presented the vascular component intermixed with the tumor. The arteriovenous-glioma association is rare and must be identified by a clear demarcation between the malformation and the tumor.
