目的探讨胸腔巨大脂肪肉瘤的CT表现特征。方法回顾性分析经手术病理证实的5例胸腔内巨大脂肪肉瘤的CT表现特点。5例患者术前均接受CT平扫,其中2例接受CT增强扫描。结果 5例胸腔内巨大脂肪肉瘤,CT扫描均表现为巨大软组织肿块,密度不均匀,其内含脂肪低密度影,邻近肺组织受压;4例邻近胸膜增厚粘连;3例心脏纵隔受压移位;2例增强扫描均呈实性部分轻度强化,脂肪部分无强化。结论胸腔内巨大脂肪肉瘤CT表现具有一定特征性,CT平扫为密度不均匀的巨大软组织肿块,其内可见含脂肪的低密度影。邻近器官和组织表现为受压推移或侵犯。增强扫描肿瘤实性部分轻度均匀强化,脂肪部分不强化。
Objective To investigate the CT features of giant liposarcoma in the chest. Methods The CT features of 5 cases of giant liposarcoma in the chest proved by surgery and pathology were retrospectively analyzed. Five patients underwent CT scan before surgery, and two of them underwent CT enhanced scan. Results In 5 cases of giant liposarcoma in chest, CT scan showed massive soft tissue mass with uneven density, which included low density of fat and adjacent lung tissues, 4 cases of adjacent pleural thickening, 3 cases of mediastinal compression Shift; 2 cases of enhanced scan showed a slight enhancement of the solid part of the fat part of no strengthening. Conclusions CT findings of giant liposarcoma in chest have some characteristic features. CT scan is a huge soft tissue mass with uneven density, which can be seen with low density of fat. Adjacent organs and tissues showed pressure to move or infringe. Enhance the solid part of the scan slightly enhanced uniform, fat part is not enhanced.
