[Glioblastoma fed by meningeal branches of the external carotid artery: a case report].
A rare case of glioblastoma fed by meningeal branches of the external carotid artery was reported. A 63-year-old female was transferred to our hospital suffering from gait disturbance and dysarthria. CT and MRI revealed brain tumor and paratumoral hemorrhage with a large cyst that was heterogeneously enhanced and existed in the right fronto-temporal region. Right external carotid arteriography demonstrated the tumor stain markedly fed by the right middle meningeal artery and the accessory meningeal artery. Subtotal removal operation was carried out uneventfully using the right fronto-temporal craniotomy. The histological diagnosis was glioblastoma. After the operation the patient was in good condition, and was transferred to another hospital for the purpose of the synchronized chemoradiotherapy. It is well known that any glioma invades the meninges. However, we rarely encountered an intra-axial glioma fed by a meningeal blood supply. A meningeal-invaded glioma may make difficult its differentiation from meningioma. We concluded that there is necessity for close examination of the intra-axial brain tumors invaded and fed by meningeal blood supply.
