The location of metastases was grouped according to sternal anatomy. The metastases in the sternum and other non-sternum bones were classified as lytic, sclerotic, and mixed. Sternal metastases were grouped according to their primary malignancy. For sternal metastases, the maximum standard uptake value (SUVmax) was measured on PET-CT. The presence of metastases in the lung parenchyma was evaluated when sternum metastases were detected. The data obtained from the study were transferred to a computer and evaluated using a statistical package program (SPSS version 15.0) at a statistical significance value of p≤0.05. Among the 69 patients, the primary diagnosis was lung cancer in 29.0% (n=20), prostate cancer in 27.5% (n=19), and breast cancer in 21.7% (n=15). In the sternum localization, the CT imaging revealed corpus involvement in 89.8% (n=62), manubrium involvement in 57.9% (n=40), and xiphoid involvement in 11.6% (n=8). The maximum lesion density ranged from 26 to 974 HU with a median of 352 HU. The maximum lesion diameter ranged from 3.0 to 32.1 mm in the axial section, with a median of 11.61 mm. The most common type of metastasis was sclerotic (60.9%) in the sternum and was multiple sclerotic (50.7%) in non-sternum bones. Of the patients, 15.9% (n=11) had metastasis both in the sternum and lung parenchyma. The most common corpus sternum involvement was found in lung cancer, while manubrium and xiphoid involvement was most observed in prostate cancer. Sclerotic metastasis involvement was also most frequent in prostate cancer. Lesion density was higher in prostate cancer than other types of cancer. No difference was found between the types of cancer in terms of the diameter of lesions in the axial section or the measured SUVmax values. CT is an important diagnostic tool in the detection of sternum metastases and should be correlated with PET-CT. It should be kept in mind that low SUVmax values can be obtained, especially in lung cancers. Among primary malignancies, corpus sternum metastasis was most common in lung cancers and manubrium and xiphoid metastases in prostate cancers. Furthermore, corpus sternum involvement was found to be the most common localization, indicating that especially the corpus sternum should be carefully evaluated in the scanning of metastases. </span> </div>}, number={1}, publisher={Eskişehir Osmangazi Üniversitesi}
