| 目的 探讨胸部高分化及黏液型脂肪肉瘤的影像学及病理特征。方法 回顾分析8例经病理证实的胸部高分化（5例）及黏液型（3例）脂肪肉瘤的影像学及病理资料。所有患者术前均接受CT平扫及增强扫描。结果 8例脂肪肉瘤中（胸壁3例、纵隔5例），肿块大小7.0 cm×4.0 cm×6.3 cm~22.8 cm×14.7 cm×15.1 cm；2例密度均匀（1例为完全软组织密度，1例为完全囊性密度），6例不均匀；3例含脂肪密度，5例无脂肪密度。平扫CT值－86~60 HU，增强后实性部分强化，8例中7例轻度强化或无强化、1例中度强化伴局部明显强化。8例中，7例肿瘤包绕或侵犯周围组织。结论 胸部高分化型及黏液型脂肪肉瘤的CT表现具有一定特征，且与病理类型密切相关。 |

| Objective To explore CT and pathologic features of thoracic well-differentiated and myxoid liposarcoma. Methods Clinical and imaging characteristics of 8 patients with thoracic liposarcoma (5 well-differentiated liposarcoma and 3 myxoid liposarcoma) proved with pathology were retrospectively analyzed. Plain and contrast enhanced CT were performed on all 8 patients. Results The size of tumors (including 5 from mediastinum and 3 from chest wall) ranged 7.0 cm×4.0 cm×6.3 cm—22.8 cm×14.7 cm×15.1 cm. Tumors in 2 patients showed homogeneous density (1 showed completely soft tissue density, the other showed wholly cystic density), while in 6 had inhomogeneous density. Fat density in the tumor was detected in 3 patients and no fat density in 5 cases. CT value for tumors on plain CT ranged from －86 to 60 HU. The masses enhanced slightly (n=7) to moderately (n=1), and the latter showed significantly local enhancement. Tumors violated surrounding tissue in 7 patients. Conclusion CT features of thoracic well-differentiated and myxoid liposarcoma are relatively specific,which are closely related to pathologic changes. |
