目的探讨MRI和CT诊断孤立性纤维性肿瘤的临床价值。方法选取本院2013年8月—2015年3月收治的孤立性纤维性肿瘤患者22例,均经病理学检查确诊,患者均进行CT扫描,对其中9例同时实施MRI检查,对患者肿瘤的大小、位置、密度、形状及信号强度等影像学资料进行回顾性分析。结果 CT能够很好地反映周围结构同病灶之间的关系,类圆形或圆形肿瘤14例,不规则形8例,存在分叶征7例。其中14例肿瘤的边缘规则,包膜不完整或完整;8例边界模糊,包膜不完整或无包膜;9例患者行MRI扫描,其中6例患者边缘清晰,3例边缘模糊,T1WI均为等低信号,T2WI则主要为稍高或高信号,增强存在明显强化。结论 CT检查能够有效反映孤立性纤维性肿瘤的大小、形态、位置、强化特征及其同周围结构的关系,而MRI的信号变化则可有效地对病灶的组织学成分进行反映,同时结合MRI和CT检查能够有效帮助临床医师对孤立性纤维性肿瘤进行早期鉴别诊断,从而为临床早期治疗提供可靠依据。
Objective To investigate the clinical value of MRI and CT in the diagnosis of solitary fibrous tumor. Methods Twenty-two patients with solitary fibrous tumor admitted from August 2013 to March 2015 in our hospital were diagnosed by pathological examination. All patients underwent CT scan. Nine of them were examined by MRI at the same time. Size, location, density, shape and signal intensity imaging data were retrospectively analyzed. Results CT can well reflect the relationship between the surrounding structure and lesions, including 14 cases of round or round tumors, irregular shape in 8 cases, there are lobular signs in 7 cases. Of the 14 cases, the edge of the tumor had an incomplete or complete envelope, 8 cases had blurred borders, incomplete or no envelope, and 9 patients underwent MRI scans, of which 6 had clear edges, 3 had edge blurred, and T1WI For the low signal, T2WI is mainly for slightly higher or high signal, enhanced significantly enhanced. Conclusion The CT examination can effectively reflect the size, shape, location, enhancement characteristics and the relationship with the surrounding structure of solitary fibrous tumor. However, the signal changes of MRI can effectively reflect the histological components of the lesion. Combined with MRI and CT examination can effectively help clinicians in the early differential diagnosis of solitary fibrous tumors, which provide a reliable basis for early clinical treatment.
