Atypical origin of the middle meningeal artery from the cervical internal carotid artery is a rare angiographic finding. We describe a case of the pharyngo-tympano-stapedial variant of the middle meningeal artery in a young patient. In this vascular variation the proximal segment of the middle meningeal artery, corresponding to an annexed inferior tympanic artery, originates from the cervical carotid artery. Then over the promontory it unites with the superior tympanic artery and continues with its intracranial course via the petrous branch.
脑膜中动脉起自颈内动脉的非典型起源是一种罕见的血管造影表现。我们描述了一名年轻患者中脑膜中动脉咽鼓管-鼓室-镫骨肌支变异的病例。在这种血管变异中,脑膜中动脉的近端段,相当于附属的下鼓室动脉,起自颈内动脉。然后在岬部上方它与上鼓室动脉汇合,并通过岩支继续其颅内行程。
