Dumbbell shaped malignant schwannoma; a case report.

Dumbbell-Shaped Abducens Schwannoma: Case Report

Schwannomas of the abducens nerve are uncommon. Nineteen cases have been reported in the literature and are classified into two types: Type 1, in the cavernous sinus, and Type 2, in the prepontine area. However, a dumbbell-shaped type has not yet been reported. Here we report the first case of a dumbbell-shaped abducens schwannoma and classify this type into a new category (Type 3). A 36-year-o...

Huge dumbbell shaped glossopharyngeal schwannoma

Schwannomas arising from the 9th, 10th and 11th cranial nerves (also called jugular foramen schwannoma) without associated neurofibromatosis are relatively uncommon [1]. Schwannomas arising from the glossopharyngeal nerve are rare and fewer than 50 cases have been reported in the literature [1-4]. Glossopharyngeal schwannoma presenting in childhood is extremely rare and to our knowledge only 4 ...

Dumbbell-shaped primitive neuroectodermal tumor mimicking trigeminal schwannoma: a case report and review of literature.

Primitive neuroectodermal tumor (PNET) is presumably of neural crest origin, and cases of supratentorial PNET in adult are extremely rare. We reported a case of PNET presenting as a dumbbell-shaped tumor at the middle cranial fossa of skull base mimicking trigeminal schwannoma both clinically and radiologically. The patient underwent surgery on July 13, 2010, using a combination of subtemporal,...

Giant recurrent dumbbell-shaped hypoglossal schwannoma in an elderly male: A case report.

Dumbbell-shaped hypoglossal Schwannomas of the 12th cranial nerve are extremely rare, and complete removal of these tumors is difficult, particularly in elderly patients with recurrent tumors. The present study reports the case of a 61-year-old male with a giant recurrent dumbbell-shaped hypoglossal schwannoma that arose extracranially. The recurrent tumor was completely removed in a one-stage ...
