Different signal intensities between intra- and extracranial components in jugular foramen meningioma: an enigma.

Primary Malignant Cerebellopontine Angle Melanoma Presenting as a Presumed Meningioma: Case Report and Review of the Literature.

Primary intracranial melanomas are rare, especially in the primary cerebellopontine angle. We describe a patient with a presumed jugular foramen meningioma that was found to be of melanotic origin at surgery. We followed this 26-year-old woman with mild ataxia with serial imaging for 18 months after the initial discovery of a cerebellopontine angle extra-axial mass. She developed worsening symp...

Jugular foramen neurilemmoma mimicking an intra-axial brainstem tumor--a case report.

Jugular foramen neurilemmoma is frequently manifested as a jugular foramen syndrome or extraaxial mass. Neurilemmoma arising from the cranial nerves of the foramen, although rare, may be manifestated as an intracranial or extracranial mass lesion. When the tumor is located only in the intracranium, it is often misdiagnosed as an acoustic neurinoma or a brainstem tumor because of their similarit...

Infratemporal Approach For Jugular Foramen Meningioma

The properties of tumours of the jugular foramen are presented and the details of the infratemporal A approach. a new technique for neurosurgeons. are discussed.

Jugular Foramen Meningioma with Transverse and Sigmoid Sinuses Invasion and Jugular Vein Extension.

Extracranial Intraluminal Extension of Atypical Meningioma within the Internal Jugular Vein

Meningiomas represent the most common benign intracranial neoplasms, and may spread by direct extension into nearby venous sinuses, but gross spread to the extracranial venous system is uncommon. We report the case of a patient with extracranial intraluminal spread of meningioma within the internal jugular vein to level III of the neck. Review of the preoperative assessment and management is al...
