A 52-year-old female came to this institution complaining of a right leg mass lesion. Ultrasonography showed a 16 x 12 x 20mm hypoechoic solid mass lesion in the right leg. The patient underwent surgery during the diagnosis of Schwannoma. Preoperative diagnosis of Schwannoma is difficult by examination. Computerized tomography and magnetic resonance imaging, showed the origin of Schwannoma. However, the lesion was noted to be in a direct continuity with the cord-like echogenic structure consistent with a nerve by echography. We prefer to conduct preoperative examination by ultrasonography in patients with Schwannoma. In conclusion, we have reported a case of Schwannoma diagnosed by non-invasive ultrasonography.

Mastoidectomy is critical in acoustic neuroma surgery, where precise planning of the bone milling area is essential for surgical navigation. The complexity of representing the irregular volumetric area and the presence of high-risk structures (e.g.

: Vestibular symptoms can severely affect patients with vestibular schwannomas (VSs). Studies assessing vestibular symptoms beyond clinical routine assessment in patients with VS treated by stereotactic radiosurgery (SRS) are scarce. Therefore, we employed the standardized questionnaire Dizziness Handicap Inventory (DHI) to systematically evaluate vestibular symptoms prior to and after SRS.

: Charcot-Marie-Tooth (CMT) disease is an inherited peripheral neuropathy primarily involving motor and sensory neurons. Mutations in INF2, an actin assembly factor, cause two diseases: peripheral neuropathy CMT-DIE (MIM614455) and/or focal segmental glomerulosclerosis (FSGS). These two phenotypes arise from the progressive degeneration affecting podocytes and Schwann cells.

Postoperative facial nerve (FN) dysfunction is associated with a significant impact on the quality of life of patients and can result in psychological stress and disorders such as depression and social isolation. Preoperative prediction of FN outcomes can play a critical role in vestibular schwannomas (VSs) patient care. Several studies have developed machine learning (ML)-based models in predicting FN outcomes following resection of VS.

Occurrence in the paravertebral region is comparatively rare and it requires differentiation from neurogenic tumours by imaging. In our patient, preoperative imaging findings were atypical of schwannoma.
