TB Bone Disease CT –CAP in the sagittal projection shows extensive lytic lesions of the T11 (red arrow) and L2 (green arrow) vertebral bodies. In addition, there is an extensive lytic lesion from S2 inferiorly (blue arrow) with an associated soft tissue mass. There are no additional lesions in the thoracic or lumbar spine. These findings may represent metastatic disease, or possibly an infectious etiology such as tuberculosis.Courtesy Joseph Cannella,Dr. Christina LeBedis, MD, MS GIBBUS SPINE27-year-old female with history of childhood TB of the spine, (Potts disease) with subsequent healing with severe deformity characterized by sharp angulation over a short segment of disease.Ashley Davidoff MD GIBBUS SPINE27-year-old female with history of childhood TB of the spine, (Potts disease) with subsequent healing with severe deformity characterized by sharp angulation over a short segment of disease.Ashley Davidoff MD TCV Map Introduction TB Cases
