Abstract

The malignant psoas syndrome (MPS) is a rare and challenging cancer pain state that is often refractory to rational polymodal analgesic therapy. We describe the first case of cervix cancer-related MPS due to extrinsic psoas muscle infiltration and review the therapeutic trajectory and outcome. The anatomic determinants, pain mechanisms, and current and proposed novel treatment strategies for MPS are discussed.
