摘要
目的:探讨孤立性纤维瘤性肿瘤的CT表现,提高对本病的认识与诊断水平。方法:回顾性分析15例经手术病理证实的孤立性纤维瘤性肿瘤的CT表现。结果:①胸腔8例(6例起源于脏层胸膜、2例起源于壁层胸膜),右肺1例,腹腔1例,盆腔2例,右鼻腔、左上颚及左上臂各1例。②肿瘤呈卵圆形7例,类圆形5例,铸型样2例,圆锥形1例;8例胸腔病灶宽基底贴附于胸膜、塑形性生长、4例跨叶间裂。③肿瘤边缘光整,12例有浅分叶,6例密度不均匀,4例可见钙化。④增强扫描6例见丰富的肿瘤血管,9例见"地图样"强化、其内均可见"多发结节状"强化,延迟强化。④3例伴胸腔积液,2例伴邻近压迫性肺不张,1例伴邻近肋骨骨膜增生。结论:孤立性纤维性肿瘤的CT表现具有一定的特征,正确认识其CT影像学特点,可对大多数病例做出正确诊断。
Purpose: To investigate the specific CT findings of solitary fibrous tumor ,and to improve the ability in understanding and diagnosing of this disease. Method: CT features of solitary fibrous tumor confirmed by surgery and pathology in 15 cases were retrospectively analyzed. Results: (1) Eight of 15 patients with solitary fibrous tumor were located in the chest, 6 originated from visceral pleura and 2 originated from parietal pleura, 1 in right lung, 1 in intra-abdominal, 2 in pelvis, 1 in upper arm, 1 in nasal cavity and 1 in palate. (2)The shape of tumor was orbicular-ovate in 7 cases, round or oval in 5 cases, casting mold in 2 cases, gourd-shaped conic in 1 case; with wide base connected to the pleura in 8 cases of the solitary fibrous tumor in the chest, 4 with straddling lobe distribution. (3) CT findings were well-difined and smooth contour in all masses. Tumors were shallow lobulated in 12 cases. Six cases showed heterogeneous density. Calcification was found in 4 cases. (4) After enhanced scan, 6 cases showed abundant tumor vessels, 9 cases showed geographic pattern enhancement and multiple nodular enhancement, and remarkable contrast enhancement was also shown in delayed phase. (5) Pleural effusion in 3 cases, compressed atelectasis in 2 cases, costal bone hyperplasia in 1 cases. Conclusion: CT can reveal the characteristic findings of solitary fibrous tumor, correctly understand these can help us to make the correct diagnosis in most cases.
