Cerebral angiofibroma: case report.
Paraules clau
Resum
OBJECTIVE
Intracranial fibromatous tumors are very rare lesions, with few reported cases.
METHODS
We report the case of a 34-year-old male patient who experienced seizures resulting from a cystic lesion in the left occipital region, which remained unchanged for 11 years. After the seizures increased in number, magnetic resonance imaging revealed a large cyst with a tumor nodule.
METHODS
A left occipital craniotomy was performed, and the tumor was removed. Pathological studies, including immunohistochemical and ultrastructural analyses, indicated that this neoplasm was composed of fibrous and angiomatous components, and a diagnosis of cerebral angiofibroma was established.
CONCLUSIONS
Cerebral and meningeal fibromas are rare neoplasms that differ from solitary fibrous tumors and fibrous meningiomas. When a number of prominent blood vessels are present in a cerebral or meningeal fibroma, a diagnosis of angiofibroma can be considered. It is possible that some nodular brain tumors that were previously described as meningioangiomatosis could be reclassified as cerebral or meningeal angiofibromas.
