Middle Meningeal Artery Arising from the Basilar Artery

Middle Meningeal Artery Arising from the Basilar Artery

An extremely rare variation of the (left) middle meningeal artery (MMA) originating from the basilar artery, detected incidentally during cerebral angiography, is reported. The right MMA was normal and an accessory meningeal artery arising from the maxillary artery was present on both the sides. The foramen spinosum on the variant side was absent. This abnormal origin of the MMA can be explaine...

Angiographically Progressive Change of Traumatic Pseudoaneurysm Arising from the Middle Meningeal Artery

Traumatic pseudoaneurysms of the middle meningeal artery (MMA) are rare phenomenon, which are usually associated with head trauma such as an underlying skull fracture. They were usually known to cause acute or delayed epidural hematomas but can be associated with subdural, subarachnoid, or even intracerebral hemorrhage. Sometimes, a high mortality rate was reported in these circumferences. But ...

Middle meningeal artery aneurysm: Case report

BACKGROUND Aneurysms of meningeal middle artery (MMA) are extremely rare. These aneurysms are of two types: true aneurysm and pseudoaneurysm. The true type is usually seen with pathologic conditions. Pseudoaneurysms, on the other hand, are associated with a skull fracture. Epilepsy caused by MMA aneurysm has never been described to our knowledge. We report a case of true aneurysm isolated from ...

Classification of the ophthalmic artery that arises from the middle meningeal artery in Japanese adults.

In a study of Japanese adults, we found that the orbital branch (OB) passing through the superior orbital fissure frequently anastomosed with the lacrimal artery or the ophthalmic artery (12/20). However, the OB passing through the meningo-orbital foramen (mof) only associationaly anastomosed with branches of the ophthalmic artery (4/79). Furthermore, the OB in the orbit, excluding the lacrimal...
