Schwannomas most commonly manifest as acoustic neuromas in the vestibulo-cochlear nerve (CN VIII). These may occur unilaterally as primary tumors, or bilaterally secondary to neurofibromatosis type 2. More rarely, they present in extra-cranial sites, including the gastrointestinal tract. Gastrointestinal schwannomas are believed to arise from Auerbach's plexus in the muscularis propria, and are...

In the central nervous system, cerebellopontine angle (CPA) lymphomas are rare; few cases have been reported. Lymphoplasmacytic lymphoma (LPL) in the CPA is rarer still, and often misdiagnosed as acoustic neuroma.We report a rare case of CPA LPL-a challenging diagnosis guided by clinical presentations, radiological signs, and postoperative pathological test.A 43-year-old woman presented with he...

Neurofibromatosis (NF) is divided into two types, NF type 1 and NF type 2. Optic nerve gliomas have a high degree of association with NF type 1. NF 2, less commonly seen, is a complex of cutaneous and deep neural tumors. It is an autosomal dominant familial disorder in which CNS is affected in about 15% of the cases. Bilateral acoustic neuromas are pathognomonic of NF type 2 which may be associ...

Intracranial tumors represent a significant health problem. The annual incidence of primary and secondary central Nervous system neoplasms ranges from 10 to 17 per 100.000 persons. The main histological types of brain tumors in adults include: high-grade (gliomas, primary cerebral lymphomas, medulloblastomas), low-grade (meningiomas, acoustic neuromas, neu‐ rofibromas) and Secondaries (common m...

Despite the great overall success of endovascular therapy for treatment of both ruptured and unruptured aneurysms, the endovascular treatment of wide‐necked bifurcation aneurysms remains challenging. The WEB device was created as a novel treatment for these aneurysms, for which balloon‐ or stent‐assisted coiling, and surgery remain as alternatives, although often challenging. The WEBCAST Key pe...

V estibular schwannoma is a benign tumour that originates from the distal parts of the vestibular or cochlear nerve. The vestibule is an unusual location for acoustic neuromas. The primary symptoms of such tumours are unilateral hearing loss, tinnitus, and vertigo. In this article, we report a patient with vestibular schwannoma who presented with the typical complaints and audiologic findings o...

When Policy Topic is covered Stereotactic radiosurgery using a gamma or LINAC unit may be considered medically necessary for the following indications:  arteriovenous malformations;  acoustic neuromas;  pituitary adenomas;  non-resectable, residual, or recurrent meningiomas;  craniopharyngiomas;  glomus jugulare tumors;  solitary or multiple brain metastases in patients having good perfo...

Background Inherited cancer syndromes associated with acoustic neuroma (i.e. neurofibromatosis 2-NF2), pheochromocytoma (i.e. Von Hippel Lindau, NFl, multiple endocrine neoplasia syndromes, and hereditary paraganglioma syndrome), and colon cancer are well known. Lynch syndrome is the most common hereditary colon cancer syndrome and is caused by DNA mismatch repair dysfunction secondary to inher...
