Cerebellopontine angle lipoma in asymptomatic patients: case report.
Lipomas represent approximately 0.15% of cerebellopontine angle tumors.1 Audiometric findings include unilateral or asymmetrical sensorineural hearing loss with low speech recognition index (SRI).2 Imaging procedures, particularly nuclear magnetic resonance (NMR), confirm the diagnosis.1--4 There is no image enhancement with gadolinium; in this scenario, special fat suppression sequences are pa...
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 کاملSecondary 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 ...
متن کاملCerebellopontine Angle Epidermoid Cyst: Case Report
Epidermoid cysts are rare congenital tumors of the central nervous system (CNS), histologically benign and slowgrowing lesions. Their frequency among primitive intracranial tumors is about 1% and they account for 40% of all intracranial epidermoid of the cerebellopontine angle (CPA); there they constitute the third most frequent neoplasm (5%), after acoustic neuromas and meningiomas. We report ...
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...
