Radiograph blastic lytic and mixed metastases

The images are from different patients and show different patterns of osseous metastases in radiographs. Arrowheads indicate lytic disease and arrows indicate blastic disease. Image A is a lateral skull radiograph from a patient with prostate carcinoma and shows two well defined blastic metastases. Image B is a lateral skull radiograph from a patient with lytic metastases and show irregularity of the zone of transition between the lytic lesion and normal surrounding bone (arrowheads). Image C is a lateral skull radiograph from a patient with multiple myeloma and also shows lytic disease. Image D is a lateral radiograph of the thoracic spine in a patient with blastic metastases (single arrow). Image E is an AP radiograph of the pelvis of a patient with lung carcinoma which shows a lytic metastasis in the right greater trochanter (arrowhead). The metallic T-shaped structure in the pelvis is an IUD. Image F is an AP radiograph of the pelvis in a patient with treated breast carcinoma which shows both lytic (arrowhead) and blastic disease (arrow) in the left femoral neck.
