title: "Photopenic" bone lesion secondary to erector spinae muscle infiltration by breast carcinoma.
abstract: A bone image demonstrating a "photopenic" vertebral lesion was found to be caused by tumor infiltration of adjacent muscle and probable secondary osseous ischemia. Magnetic resonance imaging was valuable in detecting the muscle abnormality.
