孤立性胸膜纤维瘤的临床影像特点

The clinical imaging featues of solitary pleural fibroma

目的:探讨孤立性胸膜纤维瘤的临床影像表现,以提高对该病的诊断能力。方法:随机搜集资料完整的孤立性胸膜纤维瘤4例,病例均经手术病理证实,结合文献资料就其临床影像表现进行分析总结。结果:4例患者中,男性1例,女性3例。发生于左肺斜裂上部1例,发生于左肺斜裂下部1例,发生于两下肺底部各1例。平片检查,孤立性胸膜纤维瘤均表现为以胸膜为基底或靠近胸膜的软组织肿块,病灶界限清晰,可呈圆形、椭圆形,密度均匀,病灶最大者为13cm×9cm,最小者为2cm×2cm。CT检查,肿瘤与正常胸膜表面相连处呈锐角,2例密度均匀,2例密度不均匀,病灶内可见坏死区,强化扫描病灶可明显强化。结论:孤立性胸膜瘤具有一定的临床影像特点,胸部X线、CT检查是发现和诊断本病的主要影像检查方法。

Objective： To investigate the clinical imaging features of solitary pleural fibroma,so as to improve the clinical imaging diagnostic ability. Methods：Collect solitary pleural fibroma 4 cases randomly, all the patients had completely clinical imaging material and proved by histopathology, and combine the interrelated documental material, to analysis the clinical imaging manifestation. Results：Among 4 cases, male 1 case, female 3 cases. 1 lesion was situated in the left upper oblique fissure, 1 was situated in the left lower oblique fissure, situated each base of lung was 1 case respectively. On X-ray films, all the solitary pleural fibroma manifested soft mass using pleura as the base or close to pleura. The lesions had ckear edge, can expressed as round, elipse, the density is even. Checked with CT, The joining edge of the tumor with pleural surface can expressed acute angle. The density was even in 2 cases, uneven in 2 cases, and necrosis area can be found in the lesion. The tumor can expressed enhancement obviously when enhunced scanning. Conclusion： Solitary pleural fibroma has specific clinical imaging featues, thoracic check with X-ray and CT is the main method for finding and diagnosing the disease.
