Abstract
The simultaneous presence of a giant intracranial meningioma and an arteriovenous malformation(AVM)in the same cerebral hemisphere is extremely rare. The treatment should be individualized depending on the case.
A 49-year-old man presented with hemiparesis. Preoperative neuroimaging revealed a giant lesion and an AVM on the left hemisphere of the brain. Craniotomy and tumour resection were performed. The AVM was not treated and needed to be followed up. The histological diagnosis was meningioma (World Health Organization grade I). The patient was in good neurological condition postoperatively.
This case adds to the growing literature suggesting that the association between the two lesions is complex. Besides, treatment depends on the risk of neurologic function damage and hemorrhagic stroke of meningiomas and AVMs.
