Hemifacial Spasm and Neurovascular Compression
Hemifacial spasm (HFS) is characterized by involuntary unilateral contractions of the muscles innervated by the ipsilateral facial nerve, usually starting around the eyes before progressing inferiorly to the cheek, mouth, and neck. Its prevalence is 9.8 per 100,000 persons with an average age of onset of 44 years. The accepted pathophysiology of HFS suggests that it is a disease process of the ...
متن کاملHemifacial spasm and recurrent stroke due to vertebrobasilar dolichoectasia coexisting with saccular aneurysm of the basilar artery: a case report.
We describe a patient presented with sequential events of hemifacial spasm, cerebral infarction and fatal subarachnoid hemorrhage. All of them are seemingly separate entities. Radiological examination revealed that the cause was vertebrobasilar dolichoectasia (VBD) coexisting with a giant saccular aneurysm of basilar artery. VBD is a dilatation and elongation of vertebral artery (VA) and basila...
متن کاملCT and hemifacial spasm.
Forty-six patients with typical hemifacial spasm had CT. Thirty-eight (83%) were abnormal, including two with surgically documented tumors. Thirty-six had a characteristic dolichoectatic vertebrobasilar artery, with the convexity pointing to the side of the spasm in 92% of the scans. This study suggests that CT is worthwhile procedure in the evaluation of hemifacial spasm and that dolichoectati...
متن کاملHemifacial spasm and pontine compression caused by a giant vertebrobasilar dolichoectasia.
rant artery or cerebellopontine angle masses [2, 3] . The offending vessels are usually arterial structures, such as the anterior or posterior inferior cerebellar arteries [4] . We present the case of a patient with HFS secondary to compression by a giant vertebrobasilar dolichoectasia (VBD) and highlight the possible association of HFS with VBD and type 1 neurofibromatosis (NF-1). A 70-year-ol...
متن کاملHemifacial spasm and neurovascular compression syndrome.
patient was resting, causing contraction of all the muscles innervated by the left seventh cranial nerve. MR angiography revealed a neurovascular compression of the left facial nerve by the anterior inferior cerebellar artery (AICA) (figures 1 and 2). The patient was taken to surgery and a microvascular decompression through a retrosigmoid approach was performed. Facial nerve function monitorin...
