Abstract
Schwannoma is the most common tumor of the peripheral nerve cells and originates from Schwann cells. Tumors arising from the nerve sheath are solitary and are well-defined. Schwannoma is a nerve sheath tumor that occurs along the peripheral nervous system. It presents as a solid, mobile and painless swelling. Schwannoma is often difficult to diagnose preoperatively. There are a variety of radiological imaging techniques for the assessment of  peripheral nerve sheath tumors. The imaging modalities such as Ultrasonography (USG), Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) are useful. Fine Needle Aspiration Cytology (FNAC) is also very helpful for confirming the diagnosis. We are presenting a case report of schwannoma of the sciatic nerve which presented as pain in the left thigh and was diagnosed by various imaging modalities.
