Secondary or Symptomatic Hemifacial Spasm Caused by a Tumor of Cerebellopontine Angle: Case Report and Review of Literature
نویسندگان
چکیده
Background & Importance: Primary hemifacial spasm is usually caused by microvascular compression of the facial nerve at its root exit zone at brainstem without any space-occupying pathology. Secondary or so-called symptomatic hemifacial spasm has an additional underlying pathology e.g. tumors leading to the microvascular compression. We review and discuss the pathophysiology and the literature of secondary hemifacial spasm. Case Presentation: We report on a 23 year-old man with a secondary right-sided hemifacial spasm in association with an ipsilateral epidermoid tumor of the cerbello-pontine angle. Conclusion: Intraoperatively, no offending vessel was observed near the root exit zone of the facial nerve. Microsurgical tumor removal relieved the patient also from his hemifacial spasm.

متن کاملHemifacial spasm caused by a cerebellopontine angle arachnoid cyst. Case report and literature review.
Arachnoid cysts involving the cerebellopontine angle are an unusual cause of hemifacial spasm. The case is reported of a 71-year old woman presenting with a right hemifacial spasm and an ipsilateral arachnoid cyst. Preoperative magnetic resonance imaging findings suggested a neurovascular compression caused by displacement of the facial-acoustic complex and the anterior inferior cerebellar arte...
متن کاملCerebellopontine angle arachnoid cyst: a case of hemifacial spasm caused by an organic lesion other than neurovascular compression: case report.
OBJECTIVE A rare case of cerebellopontine angle arachnoid cyst manifesting as hemifacial spasm (HFS) is reported. The patient is a 42-year-old woman with 10-month history of left HFS. A preoperative magnetic resonance imaging scan showed a well-demarcated area, hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging, in the left cerebellopontine angle, without contrast enhanc...
متن کاملA Case of Facial Spasm Associated with Ipsilateral Cerebellopontine Angle Arachnoid Cyst.
The authors report a rare case of right cerebellopontine angle cyst related to hemifacial spasm. The patient was a 66-year-old woman with a 3-year history of right hemifacial spasm. The cyst was diagnosed preoperatively by T2-weighted magnetic resonance imaging, which demonstrated a hyperintense area in the right cerebellopontine angle. A small artery was displaced by the cyst and compressed th...
متن کاملComputed tomographic analysis of hemifacial spasm: narrowing of the posterior fossa as a possible facilitating factor for neurovascular compression.
Hemifacial spasm can be caused by vascular compression of the facial nerve at the root exit zone from the brainstem. Several case reports suggest that narrowing of the cerebellopontine angle cistern caused by Paget's disease, abnormal elevation of the petrous bone caused by hyperplasia, or contralateral acoustic neurinoma may increase the chance of vascular compression of the facial nerve. Ther...
