Abstract

Herein we report a rare case of a sciatic nerve schwannoma causing in a 63-year-old female. A sciatic localization is rare accounting for <1% of all schwannomas. They often lead to misdiagnosis or delayed diagnosis owing to confusion with other common causes of sciatica, such as lumbar herniated disc or spinal stenosis. Magnetic resonance image is a gold diagnostic tool, and the final diagnosis is made by the histological examination. A standard surgical technique with guidance by neurophysiologic monitoring allows in most of the cases an uncomplicated removal of the tumor. Although being a rare occurrence, a thorough clinical and radiological evaluation of the sciatic nerve should be taken into consideration whenever sciatica is not otherwise explained.
