摘要
目的总结分析胸腹腔孤立性纤维瘤的CT表现及临床、病理特征,旨在提高对本病的认识。方法所有患者均有完整的平扫和增强CT以及病理和免疫组化检查资料,分析本病的CT表现并与病理对照。结果 9例孤立性纤维瘤(SFT)中,发生在胸腔6例,腹、盆腔3例。9例肿瘤直径均在5cm以上,其中2例发生在胸腔者最大径超过10cm,2例可见条片状、点状钙化,4例平扫密度均匀。增强后所有病例不均匀强化,其内有条状、小片状坏死区,实性部分轻中度强化,尤其在静脉期表现更明显,呈"地图样"强化,3例动脉期可见较多血管影。结论孤立性纤维瘤的CT表现具有一定特征性,仔细观察、分析可达到准确诊断。
Objective To analyze the CT findings of solitary fibrous tumor retrospectively in Order to improve the diag- nostic level of the disease. Methods Totally, 9 patients with SFT confirmed by surgical pathology underwent CT plain and contrast enhancement scanning before operation. CT findings were analyzed and compared with the pathological char- aeters. Results Of 9 cases, 6 cases were located in pleural cavity and 3 in abdominal and pelvic cavity. The size of all ca： ses were more than 5 cm, and the size of 2 cases located in the plreual were over 10 cm. The punctate calification was seen in 2 cases. 4 cases showed homogeneous density on CT scan and all cases showed heterogeneous enhancement, which was more distinct in venous phase and showed map-liked enhancement. More arterys were seen in 3 ccases in arterial phase. Conclusion CT findings of SFT show some definite characteristics, which contribute to make correct diagnosis.
