In this study we report a progressive sciatic mononeuropathy occurring 13 years after radiotherapy (56‐Gy prescribed dose) for a synovial sarcoma of the thigh. Conformal dosimetric reconstitution showed that irradiation was heterogeneous and that the sciatic nerve received 66 Gy over a 25‐cm length. Magnetic resonance imaging (MRI) showed muscle fibrosis and increased sciatic nerve diameter. Our observation suggests that the risk of late mononeuropathy should be considered when large‐volume and high‐dose radiotherapy includes a nerve trunk. Muscle Nerve, 2009
