[Spontaneous regression of a dura mater arteriovenous fistula of the posterior fossa].
A case of spontaneous regression of a posterior fossa dural arteriovenous malformation supplied by the left external carotid artery is reported. The patient, a 68-year-old woman, complained of pulsatile tinnitus most important at night. Two years after the malformation discovery, she presented a transient ischemic attack in the left middle cerebral artery territory. A new angiography showed that the malformation had disappeared; the left transverse sinus could not be opacified. The authors emphasise the interest of Doppler sonography for detection and follow-up of such malformations. They review the few published similar cases and discuss the different possible closure mechanisms of intracranial arteriovenous malformations.
