title: Angiographically occult dural arteriovenous malformation in the anterior cranial fossa--case report.
abstract: A 62-year-old male presented with a dural arteriovenous malformation located in anterior cranial fossa manifesting as acute right frontal intracerebral and subdural hematomas. Cerebral angiography showed only mass sign, but surgical exploration disclosed the dural arteriovenous malformation in the anterior cranial fossa. Anterior cranial fossa dural arteriovenous malformation should be considered if computed tomography reveals intracranial bleeding involving the frontal base, even if cerebral angiography does not demonstrate vascular anomalies.
