  • Look Inside

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 andMRI revealed brain tumor and paratumoral hemorrhage with a large cyst that was heterogenously en-hanced and existed in the right fronto-temporal region. Right external carotid arteriography demonstratedthe 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. Thehistological diagnosis was glioblastoma. After the operation the patient was in good condition, and wastransferred 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-axialglioma fed by a meningeal blood supply. A meningeal-invaded glioma may make difficult its differentiationfrom meningioma. We concluded that there is necessity for close examination of the intra-axial braintumors invaded and fed by meningeal blood supply.
