Secondary or Symptomatic Hemifacial Spasm caused by a Tumor of Cerebellopontine Angle Case Report and Review of the Literature
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 ...

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...

nial tumors and are histologically benign (1). A case of the transformation of an epidermoid cyst into a malignant squamous cell carcinoma has seldom been reported (2-7). The malignant transformation may have occurred from pre-existing epidermoid cysts or after the incomplete excision of an epidermoid cyst (5). The treatment of the malignant transformation of an epidermoid cyst varies from surg...

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...
