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 ...

Background: Epidermoid cyst is an uncommon intracranial lesion. The most common location is the cerebello-pontine angle (CPA). Unusual locations include intra-ventricular, sellar and supra-sellar regions as well as extra-axial in the temporal region. Patients and Methods: Ten patients were retrospectively included in this study. All patients were diagnosed and treated in Zagazig University hosp...

ancient schwannomas rarely found in the central nervous system and ancient change in an intracranial schwannoma (intracranial portion of the trigeminal nerve) is extremely rare. a seventy-year man presented with headache of 3 months duration and one episode of generalized tonic-clonic seizures. imaging findings were suggestive of left temporal high grade lesion. during surgery there was well ca...

INTRODUCTION Vestibular schwannomas (VS) account for approximately 85% of tumors in the cerebello-pontine angle, with a lifetime incidence of approximately 1 in 1000. Most are sporadic, with approximately 5% related to the tumor predisposition syndrome Neurofibromatosis Type 2 (NF2). The mainstays of management strategies are: observation, surgery, radiosurgery/radiotherapy and, for patients wi...

INTRODUCTION Langerhans cell histiocytosis (LCH) is a rare immunologic disorder, identified by immature proliferation of histiocytes which may present as systemic or focal lesions. Eosinophilic granuloma (EG) is localized from of LCH mainly involving bones such as skull, femur, spine, ribs, mandible and pelvis. Cerebello-pontine (CP) angle is a rare anatomic location for involvement by EG. PR...

Introduction: Neuropathic orofacial pain is common non-dontogenic pain. Diagnosis relies primarily on history taking with less of pathologic change visible. Trigeminal neuralgia (TGN) a neuropathic affecting the maxillofacial region fifth cranial nerve (V). Objective: To assess clinical characteristics, effective therapeutic regimen, side effect, radiographic and laboratory investigation inTrig...

Brain tumors are the leading cause of death and disability from childhood disease in developed countries. Pediatric posterior fossa tumors are often effectively controlled with a combination of surgery, radiation, and chemotherapy, depending on tumor type. White matter injury following resection of tumor and radiation treatment is associated with cognitive declines, including working memory def...
