Computed tomography examinations were performed on 74 patients who presented to the Children's Hospital of Philadelphia and the Hospital of the University of Pennsylvania with a known or suspected diagnosis of primary or secondary soft tissue sarcoma. Focal masses were detected on computed tomography study in 59 patients. These masses were classified into three broad categories: centrally necrotic masses with a large predominantly liquefactive center and higher density periphery (29); multilocular, septated masses with distinct linear bands or striations (21); and miscellaneous masses (9). The miscellaneous category included six inhomogeneous and three homogeneous masses. The apparent density differences within these sarcomas were best appreciated on dynamic postcontrast scans. The computed tomography appearance of these sarcomas may be explained by the pathologic findings of cystic degeneration, extensive necrosis, central cavitation, focal hemorrhage, and myxoid changes.
对费城儿童医院和宾夕法尼亚大学医院的74例已知或疑似原发性或继发性软组织肉瘤的患者进行了计算机断层扫描检查。计算机断层扫描研究在59例患者中检测到局灶性肿块。这些肿块分为三大类：中心坏死性肿块，主要为液化中心大且周边密度较高（29例）；多房性、有分隔的肿块，有明显的线性带或条纹（21例）；以及其他肿块（9例）。其他类别包括6例不均匀肿块和3例均匀肿块。这些肉瘤内明显的密度差异在动态增强扫描中最易观察到。这些肉瘤的计算机断层扫描表现可以通过囊性退变、广泛坏死、中央空洞形成、局灶性出血和黏液样改变的病理结果来解释。
