Neurofibromatosis type 2 (NF2)-related schwannomatosis is a genetic disorder with an autosomal dominant inheritance caused by germline alterations in the NF2 tumor suppressor gene located on the long arm of chromosome 22 [ 1 , 2 ], affecting young …

Seit drei Jahren leidet ein 18-Jähriger unter einer rechtsseitigen Nasenatmungsbehinderung. In der Rhinoskopie und den MRT-Aufnahmen zeigt sich eine glatt berandete Raumforderung der rechten Nasenhaupthöhle, die bis in den Nasenrachen reicht. An welche Diagnose denken Sie?

There are several surgical approaches for vestibular schwannoma (VS) resection. However, management has gradually shifted from microsurgical resection, toward surveillance and radiosurgery. One of the arguments against microsurgery via the middle …

Endoscopy in vestibular schwannoma surgery initially had a complementary role to the retrosigmoid microsurgical approach. With endoscopic guidance, access to the intrameatal portion of the lesions was made possible while minimizing damage to the …

In an effort to reduce the high morbidity and life-threatening complications after radical resection in large schwannoma surgery, alternative strategies of nontotal resections have emerged. To evaluate the long term clinical and oncological …

Vestibular schwannomas (VS), also known as acoustic neuromas, are benign intracranial tumours that arise from Schwann cells lining the vestibular component of the vestibulocochlear nerve. They represent 8% of all brain tumours and approximately …

Varicella zoster is found exclusively in humans. Infected people with this virus result in chickenpox followed by dormant virus within neural ganglia. This dormant virus, once activated, may affect any ganglia or nerves of the body but most …

This report describes a rare presentation of schwannoma in the thenar aspect of a surgeon and reviews the literature. A 35-year-old surgeon had a slow-growing swelling in his left thenar eminence. Clinical and radiological findings suggested it …

Meningiomas and schwannomas are common types of benign intradural extramedullary tumors, accounting for 41% and 33% of all intraspinal tumors respectively [ 1 ]. However, it is extremely rare for both types to exist concurrently in a child without …

Schwannomas are benign encapsulated neoplasms which arise from Schwann cells of the neural sheath. Ancient schwannoma is a rare variant of schwannoma which is often misdiagnosed as a malignant neoplasm owing to degenerative changes. They are known …

Vestibular schwannoma (VS) represents a pathologically benign tumor. Microsurgical techniques have been refined over prior decades, with an emphasis on maximum functional preservation and quality of life. Management decisions by surgeons and their …

Schwannomas are benign peripheral nerve sheath neoplasms that grow slowly and arise from Schwann cells. Here we report a case of an intraosseous schwannoma, with recent updates of molecular characterization and immunohistochemical data, affecting …

A Schwannoma is a benign tumour originating from Schwann cells within the peripheral, cranial, or autonomic nerves. Typically, these tumours manifest as a solitary, slow-growing mass with smooth surface, usually devoid of significant symptoms.

Schwannomas are benign tumours of the peripheral nerve sheath that can develop anywhere in the body. In the nasal cavity, they hardly ever happen. Lesions known as paranasal schwannomas make up fewer than 4% of all head and neck schwannomas. Here …
