Hemifacial Spasm Caused by Cerebellar Arteriovenous Malformation and Spasm-Relief after Nidus Removal
نویسندگان
چکیده
Secondary hemifacial spasm (HFS) occurs by a conflict between the facial nerve and intracranial pathology, such as cerebellopontine angle tumor or vascular abnormality like arteriovenous malformation (AVM) aneurysm. HFS caused AVM is rare, optimal combination of treatment options has not been established. with without microvascular decompression (MVD) was provided in previous studies, outcomes terms relief have successful. Here, we report case cerebellar AVM. symptom disappeared after nidus removal MVD nerve.

Intravascular embolization of a cerebellar arteriovenous malformation for treatment of hemifacial spasm.
Hemifacial spasm consists of involuntary contractions of the facial muscles, usually caused by vascular compression of cranial nerve VII , near its exit zone from the brainstem [17]. Arteriovenous malformations (AVMs) are a rare cause of this condition [2, 3]. We report a case of hemifacial spasm caused by an extensive cerebellar AVM, which was successfully treated by intravascular embolization .
متن کاملDelayed Dural Arteriovenous Fistula after Microvascular Decompression for Hemifacial Spasm
Dural arteriovenous fistula (AVF) is very rare, acquired lesion that may present with intracranial hemorrhage or neurological deficits. The etiology is not completely understood but dural AVF often has been associated with thrombosis of the involved dural sinuses. To our knowledge, this is the first well documented intracranial hemorrhage case caused by dural AVF following microvascular decompr...
متن کاملA successful treatment of coexistent hemifacial spasm and trigeminal neuralgia caused by a huge cerebral arteriovenous malformation: a case report.
Regardless hemifacial spasm (HFS) or trigeminal neuralgia (TN) is commonly caused by an offending artery, 36 cases caused by an arteriovenous malformation (AVM) have been reported in the literature. However, the concurrent HFS and TN caused by AVM have never been reported so far. We reported a case of coexistent HFS-TN associated with a huge AVM, and the symptoms of both spasm and pain relieved...
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 craniovertebral anomaly.
Two patients with congenital anomaly of the craniovertebral junction causing disabling hemifacial spasm (HFS) are presented. In one patient, complete cessation of the HFS occurred for a period of two years following simple bony decompression of the craniovertebral junction raising unanswered questions as to the exact pathogenesis of HFS. Eventually both patients required microvascular decompres...
