Non-invasive diagnosis of a Schwannoma by ultrasonography: a case study.
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.
