Leg paresthesias can be challenging to evaluate because of the varied causes and clinical presentations. This diagnostic guide with at-a-glance tables can help.

Magnetic resonance imaging of Ms. T’s hip and upper leg shows a 10.7 cm x 7.8 cm x 13 cm heterogeneously enhancing mass in the expected location of the right sciatic nerve (FIGURE). Biopsy reveals a high grade, poorly differentiated synovial sarcoma. Her physician refers her to an oncologist for initiation of chemotherapy, radiation, and debulking surgery.
