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

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

A 63-year-old man presented with intermittent, progressively worsening dyspnoea associated with cough and blood-tinged sputum. Initial work-up showed left axis deviation on ECG, chest X-ray with an elevated left hemidiaphragm and a non-contrast CT chest that showed a multilobulated mass in the proximal trachea. Bronchoscopy showed a whitish-appearing lesion, which was then sampled and partially resected with pathology showing a schwannoma with no malignant cells. Read More

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

Background: Surgical resection of vestibular schwannomas (VS) located within the internal auditory canal (IAC) is challenging, especially those located very laterally in the IAC. Various transcranial approaches have been described for resection of intracanalicular VS including retrosigmoid, translabyrinthine, and middle fossa approaches. Each approach has its indications, advantages, and limitations. Read More

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
