MSCT增强扫描诊断胸膜孤立性纤维瘤的价值

目的：探讨 MSCT 诊断胸膜孤立性纤维瘤(SFTP)的价值。方法回顾性分析经病理证实的12例 SFTP 患者的临床及CT 资料。结果12例 SFTP 患者中,8例出现胸闷,6例呼吸困难,5例胸痛,2例咳嗽；7例呈类圆形,5例不规则形；可见包膜6例、分叶征5例；可见坏死9例,钙化3例；病灶直径3~22 cm,平均(11.3±2.4)cm；9例与肺组织分界清晰,7例与胸壁呈锐角,增强后9例明显不均匀“地图样”强化,其中7例病灶内可见迂曲血管影,3例呈轻-中度强化。结论SFTP 在 CT 上具有一定特征性表现,尤其增强 CT 对 SFTP 具有独特优势。

The diagnostic value of MSCT contrast enhanced scan in solitary fibrous tumor of the pleura

Objective To explore the diagnostic value of MSCT in solitary fibrous tumor of the pleura(SFTP).Methods The clinical and CT data of 12 patients with SFTP confirmed by pathology were analyzed retrospectively.Results The main clinical symptom and CT findings of 12 patients with SFTP included:chest tightness(n=8),dyspnea(n=6),chest pain(n=5),cough(n=2);round (n=7),irregular(n=5);envelope(n= 6),lobulation(n= 5 );necrosis (n= 9),calcification (n= 3);the diameter was 3 - 22 cm, mean (11.3±2.4)cm;clear boundaries between lesions and lung tissue(n=9),an acute angle between lesions and chest wall(n=7);uneven obviously “map-like”enhancement after injecting contrast medium,which 7 cases of lesions can be seen in the circuitous vasculature and 3 cases was showed mild-moderate enhancement.Conclusion SFTPs have characteristic CT features,contrast enhanced CT play an unique advantage.
