目的探讨胸膜孤立性纤维性肿瘤的CT表现,提高对该疾病的认识。方法搜集经穿刺活检及手术病理证实的胸膜孤立性纤维性肿瘤6例,回顾性分析CT表现并相关文献复习。结果6例胸膜孤立性纤维性肿瘤均发生在右侧胸腔。其中1例较小肿瘤最大径约3.0cm,5例巨大肿瘤最大径均>9.0cm。CT平扫显示6例均与胸膜呈宽基底相连,边缘光滑,其中4例肿瘤密度均匀,CT值28~39HU,2例肿瘤密度略不均匀,其内可见较少区域低密度,CT值12~40HU;4例CT增强显示中度均匀强化3例,肿块内可见扭曲血管影,CT值44~52HU,CT值增加平均约12HU;1例明显不均匀强化,CT值57~85HU,CT值增加22~50HU,3例可见“假包膜征”。结论胸膜孤立性纤维性肿瘤CT表现具有一定特征。
Objective To investigate the CT findings of pleural solitary fibrous tumors and to improve their understanding of the disease. Methods Six cases of pleural solitary fibrous tumor confirmed by biopsy and surgical pathology were collected. The CT findings were retrospectively analyzed and the related literatures were reviewed. Results Six pleural solitary fibrous tumors occurred in the right side of the chest. The largest diameter of one case was about 3.0 cm, and the largest diameter of five cases was> 9.0 cm. Six cases of CT scan showed a wide base with smooth edges. Among them, 4 cases had uniform tumor density, CT value was 28 ~ 39HU, and the tumor density in 2 cases was slightly uneven. ~ 40HU; 4 cases of CT enhancement showed moderate homogenization in 3 cases, the visible distortion of the blood vessels in the mass, CT value 44 ~ 52HU, CT value increased by an average of about 12HU; 1 case was significantly uneven enhancement CT value 57 ~ 85HU, CT value An increase of 22 ~ 50HU, 3 cases can be seen “false capsule sign.” Conclusions Pleural solitary fibrous tumor has some characteristics of CT.
