What intervention is best practice for vestibular schwannomas? A systematic review of controlled studies [PDF]

, 2013
Objective: Largely, watchful waiting is the initial policy for patients with small-sized or medium-sized vestibular schwannoma, because of slow growth and relatively minor complaints, that do not improve by an intervention. If intervention (microsurgery,

Comparative evaluation of normal tissue objective functions in robotic radiosurgery planning for solitary brain tumors

Journal of Applied Clinical Medical Physics, Volume 26, Issue 11, November 2025.
Abstract Background The normal tissue objective (NTO) is an inverse planning approach in radiosurgery, also available for the CyberKnife system. By employing a model function, it aims to achieve precise control over the global dose fall‐off in healthy tissue.

Neurofibromatosis type 2 initially presenting as a preauricular mass: a case report

Journal of Otolaryngology - Head and Neck Surgery, 2020
Neurofibromatosis type 2 (NF2) is a rare genetic disease involving multiple tumors of the central and peripheral nervous systems. Most patients with NF2 have bilateral vestibular schwannomas; nonvestibular schwannomas may also develop. While the majority

Abdominal Wall Schwannoma: A Rare Case of Target Sign on Ultrasonography

Clinical Case Reports, Volume 13, Issue 11, November 2025.
The target sign observed on ultrasonography. ABSTRACT Schwannoma is a benign tumor derived from Schwann cells of peripheral nerves. Schwannomas arising within muscle or fat exhibit characteristic magnetic resonance imaging (MRI) findings called the target sign, split fat sign, or fascicular sign.

Cochlea-sparing acoustic neuroma treatment with 4π radiation therapy. [PDF]

, 2018
PurposeThis study investigates whether 4π noncoplanar radiation therapy can spare the cochleae and consequently potentially improve hearing preservation in patients with acoustic neuroma who are treated with radiation therapy.Methods and ...

Chemopreventative celecoxib fails to prevent schwannoma formation or sensorineural hearing loss in genetically engineered murine model of neurofibromatosis type 2 [PDF]

, 2017
Mutations in the tumor suppressor gene NF2 lead to Neurofibromatosis type 2 (NF2), a tumor predisposition syndrome characterized by the development of schwannomas, including bilateral vestibular schwannomas with complete penetrance.

Differentiation of vestibular schwannomas from meningiomas of the internal auditory canal using perilymphatic signal evaluation on T2-weighted gradient-echo fast imaging employing steady state acquisition at 3T

European Radiology Experimental, 2017
BackgroundOur aim was to confirm the usefulness of the perilymphatic signal changes on T2-weighted (T2W) gradient-echo sequence to differentiate vestibular schwannomas from internal auditory canal (IAC) meningiomas, through a compartmental analysis of ...

High‐Resolution Visualization of the Human Semicircular Canals Using Optical Coherence Tomography

International Journal of Imaging Systems and Technology, Volume 35, Issue 6, November 2025.
ABSTRACT The semicircular canals are essential sensors of the vestibular organ. Current clinical in vivo imaging techniques lack the resolution needed to visualize critical vestibular microstructures, such as the membranous labyrinth and crista ampullaris.
