Jugular foramen schwannoma mimicking paraganglioma: case report and review of imaging findings.
نویسندگان
چکیده
We present the case of a 30-year-old woman who presented with an 11-year history of chronic occipital headaches and a 12-month history of worsening difficulty speaking and/or swallowing, facial spasms, hearing loss, and dizziness. A large lytic mass was found centered in the left jugular foramen (JF) on computed tomography examination; follow-up magnetic resonance imaging showed an avidly enhancing mass with prominent central flow voids. Histopathologic examination after surgical resection revealed the mass to be a schwannoma. Prominent central vascularity is an unusual presentation for JF schwannomas. Our report provides a review of magnetic resonance imaging features of intrinsic JF lesions relevant to our case.

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

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...

متن کاملTotally cystic schwannoma of the tenth cranial nerve mimicking an epidermoid.
Schwannomas are usually characterized by a mass that displays rapid and intense contrast enhancement on computed tomography (CT) and magnetic resonance (MR) imaging. Although some cases are associated with cyst formation, a solid component is nearly always visualized. Schwannomas can be associated with any nerve. Schwannomas of the ninth, 1Oth, and 11th cranial nerves, also called neurinomas of...
متن کاملJugular Foramen Tumors
Jugular foramen tumors are rare cranial base lesions that present diagnostic and management difficulties. Paragangliomas were the most frequent lesions, followed by schwannomas and meningiomas. These tumors have characteristic radiological features. Radical resection of these tumors with preservation of the lower cranial nerves is the treatment of choice. Despite the advances in skull base surg...
