Schwannoma or neurilemmoma is a benign, slow-growing nerve sheath tumor arising from Schwann cells of the cranial, peripheral or autonomic nerves. Approximately 25%-40% of schwannomas occur in the head and neck region. Occurrences of intraoral schwannomas are rare with reported prevalence being 1%. Read More

Background: Schwannomas, benign tumors arising from neurolemmocytes, are the most common type of peripheral nerve tumors. Extracranial schwannomas are most often found in the parapharyngeal space, commonly involving the vagus nerve to cervical sympathetic trunk. Vagal schwannomas present several unique clinical and therapeutic challenges. Read More

Introduction: Schwannomas-Schwann cells-originating tumors-may develop in many locations. However, primary schwannomas arising within lymph nodes are extremely rare, with only a few cases described to this date in the English literature. For the intranodal location, most of the cases are described in the abdominal cavity. Read More

Painful tumors of the skin present as dermal or subcutaneous nodules. They can originate from several sources: adipose tissue, cartilage degeneration, deposition of bone or calcium, eccrine glands, fibrous tissue, infiltration of benign (endometrium) or malignant (metastatic neoplasm) tissue, muscle, nerve, or vascular structures. Although pathologic evaluation of the lesion is necessary to determine the diagnosis, it is possible to make a reasonable differential diagnosis based on knowledge of prior tumors that have appeared as tender lesions.

Primary malignant fibrous histiocytoma (MFH) of the chest wall is extremely rare and is characterized by aggressive features, including a high incidence of local recurrence and distant metastasis. Surgical resection of the chest wall is the primary modality of management. However, surgical treatment is not generally recommended in patients with evidence of distant metastasis. Read More

Background: Selecting the proper surgical approach for mediastinal tumors in the thoracic outlet is difficult. Video-assisted thoracoscopic surgery is ideal because of the less invasiveness; however, it is often difficult to resect tumors only by video-assisted thoracoscopic surgery due to the poor visualization of the cranial side of tumors. We report two successfully treated cases by using a dual approach consisting of the transmanubrial osteomuscular sparing technique and video-assisted thoracoscopic surgery for aiming both the less invasiveness and the good visualization of the cranial side of tumors.

Background: Preservation of cranial nerve function in patients with benign tumors such as meningiomas and vestibular schwannomas remains difficult following microsurgery.

Methods: In this study, awake surgery was performed in 22 consecutive patients with meningiomas or vestibular schwannomas that compressed cranial nerves (I-XII). Improved, unchanged, or deteriorated cranial nerve function after surgery was evaluated. Read More

Objectives:: To examine whether the model of Getting It Right First Time (GIRFT) could be relevant to the surveillance of non-operated vestibular schwannomas (vs) by testing the following hypotheses: (1) in the UK there is a great variation in the imaging protocol for the follow-up of vs; (2) high-resolution, T weighted MRI (HRT W-MRI) has an equivalent accuracy to gadolinium-enhanced T weighted MRI (Gd-MRI) in the assessment of vs size and; (3) imaging with HRT W-MRI rather than Gd-MRI could offer financial savings.

Methods:: Two neuroradiologists independently performed measurements of 50 vs imaged with HRT W-MRI and Gd-MRI. Differences in mean tumour measurements between HRT W-MRI and Gd-MRI were determined, as were intra- and interobserver concordance. Read More

Neurofibromatosis type II (NF2) is a disease that lacks effective therapies. NF2 is characterized by bilateral vestibular schwannomas (VSs) that cause progressive and debilitating hearing loss, leading to social isolation and increased rates of depression. A major limitation in NF2 basic and translational research is the lack of animal models that allow the full spectrum of research into the biology and molecular mechanisms of NF2 tumor progression, as well as the effects on neurological function.

Introduction: Since Lars Leksell developed the first stereotactic radiosurgery (SRS) device in 1951, there has been growth in the technologies available and clinical indications for SRS. This expansion has been reflected in the medical literature, which is built upon key articles and institutions that have significantly impacted SRS applications. Our aim was to identify these prominent works and provide an educational tool for training and further inquiry. Read More

Department of Radiotherapy, Erasmus MC Cancer Institute, Postbus 2040, Rotterdam, 3000, CA, The Netherlands.

Background: Although stereotactic radiotherapy (SRT) for vestibular schwannoma has demonstrated excellent local control rates, hearing deterioration is often reported after treatment. We therefore wished to assess the change in hearing loss after SRT and to determine which patient, tumor and treatment-related factors influence deterioration.

Methods: We retrospectively analyzed progression of hearing loss in patients with vestibular schwannoma who had received stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) as a primary treatment between 2000 and 2014. Read More

Dorsal displacement of the facial nerve is relatively rare in patients with vestibular schwannoma. Its prediction remains difficult in patients with large tumors, even with the recent advances in preoperative radiologic assessments. Anatomic and functional preservation of the facial nerves combined with maximal tumor removal is particularly challenging in this rare anatomic variant, and surgery may lead to postoperative facial dysfunction, inadequate tumor removal, and/or a high retreatment rate.

Background: Schwannomatosis is the third subtype of neurofibromatosis. Because the tumor is multiple and prone to recurrence, it often brings challenges to clinical diagnosis and treatment. In the past decade, researchers have come to realize the relationship between the SMARCB1 gene and schwannomatosis, which is expected to improve the current level of diagnosis and treatment.

Background: Compression of the trigeminal nerve by vessels and tumors causes trigeminal neuralgia. However, a tethering effect, provoking an abnormal root-stretching force, has been previously reported to play a role in trigeminal nerve hyperexcitability. We report 2 patients with vestibular schwannomas treated by stereotactic radiosurgery (SRS) who presented with typical manifestations of trigeminal neuralgia after tumor shrinkage. Read More
