目的探讨巨大胸膜孤立性纤维瘤(SFTP)的MSCT表现特点,以提高对本病的诊断率,并指导临床手术治疗。方法搜集经手术及病理证实的2例巨大SFTP患者资料,术前均行MSCT平扫及增强扫描,并行MPR、MIP、VR及CTA等图像后处理,分析总结其影像学表现特点。结果巨大SFTP为肺外胸腔内单发肿块,包膜完整,有蒂,可见分叶,于胸腔内铸型生长,密度欠均匀,血供丰富,呈地图状强化及延迟强化,常见肿瘤血管,供血动脉明确。结论 MSCT可清晰显示SFTP的大小、位置、形态、强化方式及与周围组织的关系,其增强表现具有一定特征性;MSCTA可清楚显示肿瘤血供情况及供血动脉,对制定合理的手术治疗方式具有重要意义。
Objective To investigate the features of MSCT in giant pleural solitary solitary fibroma (SFTP) in order to improve the diagnosis of this disease and guide the clinical operation. Methods The data of 2 cases of giant SFTP confirmed by operation and pathology were collected. MSCT and enhanced scan were performed preoperatively. The images were processed by MPR, MIP, VR and CTA, and their imaging features were analyzed. Results Large SFTP is a solitary mass outside the extra-pulmonary pleural cavity. The capsule is complete, pedunculated and dividable. It grows in the cavity of the thoracic cavity with uneven density and abundant blood supply. It exhibits map-like enhancement and delayed enhancement. Common tumor vessels, Blood supply artery clear. Conclusion MSCT can clearly show the size, location, shape, enhancement of SFTP and the relationship with the surrounding tissue, and its enhanced performance has certain characteristics. MSCTA can clearly show the blood supply of the tumor and the feeding artery, and has the value of establishing a reasonable surgical treatment Significance.
