Tumoren des Sternums

Young adult

treated for leukemia as a preschooler, now with new palpable sternal massAxial CT without contrast of the chest with soft tissue (above) and lung (below) windows shows a heterogeneous mass contiguous with the rectus muscles and anterior to the lower sternum which appears to be eroding into the sternum along with multiple peripheral pulmonary soft tissue nodules.The diagnosis was epithelioid sarcoma with pulmonary metastases.

Sternal

reconstruction for unusual chondrosarcoma: innovative technique. CT images show the mass into the anterior mediastinum. On the right it is possible to observe the calcified connection between the mass and the sternum; no cortical erosion is present.

A rare

desmoid tumor arising from the manubrium. Radiologic images. Chest CT axial view (A) and computed tomographic scan of the reconstructed chest (B) before surgery showed the osteolytic lesion (arrow) in the manubrium. Computed tomographic scan of the reconstructed chest (C) was followed up 3 months postoperatively.

Sternal

metastasis as an initial presentation of renal cell carcinoma: a case report. Metastatic bone disease. Bone scintigram shows uptake in the sternal body.

Sternal

metastasis as an initial presentation of renal cell carcinoma: a case report. Thoracic CT scan showing soft-tissue mass in the sternum.

Sternal

intraosseous schwannoma mimicking breast cancer metastasis. The finding of chest CT. (A) Chest computed tomography showed a round, well-defined, low-density nodule measuring 3.3 x 2.8 cm (arrows), which was located at almost the center of the sternum with bone lysis and erosion. The finding of FDG-PET/CT (B) [18 F]Fluorodeoxyglucose positron emission tomography/computed tomography demonstrated fluorodeoxyglucose accumulation (arrowheads) in the tumor. The standardized uptake value was 5.51.p.
