Skull base tumors arise from the cranial base or reach it, either from an intracranial or extracranial origin. A diverse group, these tumors present unique management challenges because of their relative rarity, typically deep location, close proximity to critical neurovascular structures, and extension beyond classically taught anatomic and specialty boundaries. Management outcomes for skull b...

A 50-year-old male with a long standing history of compulsive Valsalva maneuvers, complaining of episodes of vertigo underwent head computed tomography. Axial CT slices at the level of the skull base (Fig. A) and the first cervical vertebrae (Fig. B) shows an extensive unusual pneumatization of both the body and lateral processes of the first cervical vertebrae (arrows), with air pouches dissec...

Various surgical techniques for extirpation of anterior skull base tumors have been established over the past few years. Tumors that are located in this anatomical area may invade both soft and hard tissues of the skull base. In such cases, an en bloc tumor resection may create extensive skull base defects and produce a free conduit between the paranasal sinuses and the intracranial space. Foll...

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 ...

Ollier’s syndrome, a variant of multiple enchondromatosis, is a rare disease with an estimated prevalence of 1/100,000, characterized by multiple enchondromas, asymmetrically involving small bones of the hands and feet, especially the proximal phalanges. Intracranial enchondromas, such as those arising from the skull base are extremely rare. Herein, we report a 25-year-old female, known case of...
