CT blastic lytic and mixed metastases

The reconstructed CT images are from three different patients and reflect different patterns of metastatic bone disease. The bone windows of the spine are projected as sagittal reconstructions. The first (A) is a patient with breast carcinoma complicated by blastic metastatic disease of the thoracolumbar spine (arrow). The second (B) is a patient with multiple myeloma and multiple lytic lesions in the thoracolumbar spine (arrowheads). The third (C) is a patient with breast carcinoma with both blastic (arrows) and lytic (arrowheads) disease.
