【摘要】：目的探讨胸膜孤立性纤维瘤的CT及MRI表现及其诊断价值。资料与方法对11例经手术病理证实的胸膜孤立性纤维瘤患者的CT及MRI表现特征进行回顾性分析。结果11例11个病灶,7例来源于右侧胸膜,其中斜裂胸膜2例,水平裂胸膜3例;左侧胸膜4例,其中斜裂胸膜2例,CT表现为边界清晰的混杂密度影,其内见不规则低密度区,2例可见结节状钙化,增强扫描实性部分不同程度强化,低密度区无强化,9例可显示肿瘤内血管;MRI表现为边界清晰的混杂信号实性部分T1WI与肌肉相比呈高信号,T2WI呈等或稍低信号,囊变部分表现为长T1、长T2信号,扩散加权成像(DWI)表现为等或稍高信号;增强扫描肿瘤实性部分不同程度强化。结论胸膜孤立性纤维瘤的CT及MRI表现有一定的特征,分析其影像学特征,可做出较明确的诊断并能够与其他胸部肿瘤相鉴别。
[Abstract]:Objective to investigate the CT and MRI findings of pleural solitary fibroma and its diagnostic value. Materials and methods CT and MRI findings of 11 patients with pleural solitary fibroma confirmed by surgery and pathology were retrospectively analyzed. Results 11 cases (11 lesions) of 7 cases originated from the right pleura, including 2 cases of oblique fissure pleura, 3 cases of horizontal fissure pleura, 4 cases of left pleura, of which 2 cases of oblique fissure pleura showed clear boundary mixed density. Nodular calcification was seen in 2 cases of irregular low density area. In 9 cases without enhancement in the low density area, MRI findings of the intraneoplastic vessels showed clear boundary mixed signal solid part T1WI showed iso-or slightly low signal intensity on T _ 2WI compared with muscle, and the cystic lesions showed long T _ 1 and long T _ 2 signal intensity. Diffusion weighted imaging (DWI) showed equal or slightly higher signal intensity and enhanced solid part of tumor. Conclusion the CT and MRI findings of pleural solitary fibroma have certain features. The imaging features of solitary pleural fibroma can be clearly diagnosed and can be distinguished from other thoracic tumors.
