Case 1: 79-year-old man with metastatic leiomyosarcoma to the T11 vertebral body, s/p vertebrectomy, and reconstruction. (a, b, c). Axial, coronal, and sagittal MDCT. The position of the expandable titanium cage and anterior thoracic fusion plate is demonstrated. (d, e, f). Co-registration of sequential MDCT studies. The original study is in white color and the more recent study is in black color; a similar position of the surgical instrumentation between the two sequential studies is demonstrated. Green line denotes corresponding position of the other two orthogonal planes.
