CT image of thoracic osteosarcoma. Computed tomographic soft-tissue window after intravenous application of contrast medium in a miniature goat with thoracic osteosarcoma. Sagittal section of the right hemithorax (A) and transverse section at the level of the 8th thoracic vertebra (B). The mass extended from the thoracic inlet to the diaphragm and displaced the heart dorsally and to the right. Accumulation of contrast medium was limited to the periphery of the mass. A smaller nodular mass was seen ventral to the heart. 1 Precardial mass, 2 Heart, 3 Truncus brachiocephalicus, 4 Diaphragm, 5 Reticulum, 6 Rumen, 7 First rib, 8 Nodular mass, 9 Amorphous mineralization, 10 Peripheral accumulation of contrast medium, 11 Lung, Cr Cranial, Cd Caudal, L Left, R Right.
