目的探讨胸骨肿瘤临床CT诊断和检查意义。方法搜集分析经临床病理证实的22例胸骨肿瘤CT资料,其中转移瘤17例(肺癌转移15例;乳腺癌转移2例)、骨髓瘤2例、软骨肉瘤1例、骨肉瘤1例、骨化性纤维瘤1例。结果局部骨质破坏(囊状膨胀性、溶骨性和混合性骨破坏3种),其中囊状膨胀性骨破坏1例(骨化性纤维瘤),溶骨性骨破坏16例(肺癌转移15例、骨肉瘤1例),混合性骨破坏5例(软骨肉瘤1例、骨髓瘤2例、乳腺癌转移2例)。胸骨处软组织肿块18例,胸骨前胸壁肌、皮下脂肪和胸骨后脂肪间隙浸润13例。结论胸骨肿瘤以转移瘤多见,CT检查对胸骨肿瘤有较高的诊断价值。
Objective To investigate the clinical diagnosis and detection of sternal tumors. Methods Twenty - two cases of sternal tumors confirmed by clinical pathology were collected and analyzed. Among them, 17 were metastases (15 cases of lung metastases and 2 cases of breast cancer metastases), 2 cases of myeloma, 1 case of chondrosarcoma, 1 case of osteosarcoma, 1 case of fibromatosis. Results Local bone destruction (cystic expansibility, osteolytic and mixed bone destruction 3), including cystic expansive bone damage in 1 case (ossifying fibroma), osteolytic bone destruction in 16 cases (lung cancer metastasis 15 cases, 1 case of osteosarcoma), mixed bone destruction in 5 cases (chondrosarcoma in 1 case, 2 cases of myeloma, 2 cases of breast cancer metastasis). Thoracic soft tissue mass in 18 cases, sternum chest wall muscle, subcutaneous fat and sternal fat space after the infiltration of 13 cases. Conclusion Sternal tumors are more common in metastatic tumors, CT examination of the sternum tumors have a higher diagnostic value.
