schwannomas

This study was to explore MRI performances and features of schwannomas from cranial nerves in posterior cranial fossae.

Schwannomas are peripheral nerve sheath tumors with a slow growth rate. They rarely occur in the retroperitoneum or pelvis.

Benign peripheral nerve sheath tumors can be divided into two major groups: Schwannomas and neurofibromas.

Schwannomas and neurofibromas are benign lesions that are thought to arise from neoplastic transformation of nerve sheath cells.

Benign neurogenic tumors originating from the peripheral nervous system usually appear as schwannomas or neurofibromas.

BACKGROUND: Peripheral schwannomas and pilomatrixoma are rare clinical features in childhood.

Objective To summarize surgical experience with communicating skull base schwannomas in the jugular foramen region.

Intraparotid facial nerve schwannomas typically present as slow-growing, asymptomatic masses with a mean age at presentation of 45 years.

Three cases of benign schwannomas originating in the nasal cavity, the nasal-ethmoid, and the pterygopalatine fossa are reported.

Methods Clinical data of 10 patients with schwannomas originating from jugular foramen region were analyzed retrospectively.

Materials and Methods: Analyze MRI materials of 7 peripheral Schwannomas of the extremities proved by pathology.

Because of their variable imaging characteristics, leiomyomas are not definitely distinguished from schwannomas or fibromas.

Schwannomas in the head and neck region are uncommon, especially from the sinonasal tract.

Schwannomas are rare tumors derived from the cells of Schwann which form the neural sheath.

However, schwannomas of the colon are extremely rare.

Schwannomas are less common than neurofibromas and constitute about 5% of all benign soft tissue tumors.

They can develop in pre-existing neurofibromas or schwannomas, denovo from peripheral nerves, or following radiation therapy.

More than 25% of schwannomas are found in the head and neck region, and they are rarely found in the retropharyngeal space.

Schwannomas are not easily distinguished from other benign tumors such as neurofibromas and leiomyomas .

Objective: To study the effect of mutation of neurofibromatosis 2(NF2) gene (exon 2) in schwannomas.
