Progression of hearing loss after LINAC-based stereotactic radiotherapy for vestibular schwannoma is associated with cochlear dose, not with pre-treatment hearing level.

Radiat Oncol 2018 Dec 24;13(1):253. Epub 2018 Dec 24.

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

Brachial Plexus Schwannoma - Case Report and Literature Review.

Acta Clin Croat 2018 Jun;57(2):366-371

Department of Pathology, Merkur University Hospital, Zagreb, Croatia.

Schwannoma as an extracranial nerve sheath tumor rarely affects brachial plexus. Due to the fact that brachial plexus schwannomas are a rare entity and due to the brachial plexus anatomic complexity, schwannomas in this region present a challenge for surgeons. We present a case of a 49-year-old female patient with a slow growing painless mass in the right supraclavicular region that was diagnosed as schwannoma and operated at our department. Read More

Department of Otolaryngology-Head and Neck Surgery, Icahn School of Medicine at Mount Sinai, New York Eye and Ear of Mount Sinai, Floor 6, 310 East 14th Street, New York, NY 10003, USA. Electronic address:

Current consensus on optimal treatment of vestibular schwannoma remains poorly established; treatment options include observation, stereotactic radiosurgery, microsurgical resection, medical therapy, or a combination of these. Treatment should be individualized and incorporate the multitude of patient- and tumor-specific characteristics known to affect outcome. Treatment paradigms for sporadic and neurofibromatosis type 2-related tumors are distinct and decision-making in neurofibromatosis type 2 is uniquely challenging. Read More

Surgical management of retroperitoneal schwannoma complicated with severe hydronephrosis: A case report.

Medicine (Baltimore) 2018 Sep;97(39):e12528

Department of Urology, The Second Affiliated Hospital, Xi'an Jiaotong University.

Rationale: Schwannomas are usually benign tumors arising from well-differentiated schwann cells, which rarely occur in the retroperitoneal space. The lack of specific signs and radiologic imaging characteristics makes preoperative diagnosis rather difficult. Most retroperitoneal schwannomas are benign and the primary treatment choice for retroperitoneal schwannomas is surgical excision, however, the involvement of the urinary system is scarcely reported.

Unusual Delayed Presentation of Posterior Reversible Encephalopathy Syndrome Following Vestibular Schwannoma Surgery: A Rare Neurologic Emergency.

World Neurosurg 2018 Dec 24;120:532-536. Epub 2018 Sep 24.

Department of Neurosurgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences, Lucknow, India.

Background: Posterior reversible encephalopathy syndrome (PRES) is a rare neurologic condition that manifests with heterogeneous clinical findings, including altered mental status, seizure, vision loss, and vomiting. It characteristically leads to diffuse subcortical vasogenic edema, most commonly in the parieto-occipital regions. Although frequently reported with conditions such as hypertension, eclampsia, sepsis, electrolyte imbalances, autoimmune diseases, and immunosuppressive therapy, PRES may rarely occur after surgery for posterior fossa tumors.

Jiangsu Clinical Medicine Center of Tissue Engineering and Nerve Injury Repair, Chinese Medical Association Neuroendoscopic Training Base and Department of Neurosurgery, Affiliated Hospital of Nantong University, Nantong, Jiangsu Province, China. Electronic address:

Background: Both the pterygopalatine fossa (PPF) and the infratemporal fossa (ITF) lie outside the midline of the skull base. Lesions in the PPF or ITF include trigeminal schwannoma (trigeminal schwannoma, TS), which originates from the second or third branch of the trigeminal nerve (maxillary nerve or mandibular nerve). Due to their typically deep anatomic location, lesions in the PPF or ITF can be difficult to treat using traditional surgical approaches. Read More

False localizing sign caused by schwannoma in cervical spinal canal at C1-2 level: A case report.

Medicine (Baltimore) 2018 Sep;97(36):e12215

Rationale: False localizing sign means that the lesion, which is the cause of the symptom, is remote or distant from the anatomical site predicted by neurological examination. This concept contradicts the classical clinicoanatomical correlation paradigm underlying neurological examinations.

Patient Concerns: A 54-year-old man consulted for the right sciatica-like leg pain that had aggravated 1 year ago. Read More
