摘要:
目的 探讨腹部孤立性纤维瘤(SFT)的CT表现特点及其与病理结构的关系。
方法 回顾性分析12例经病理证实的腹部SFT的CT及其相应的病理表现。
结果 SFT病人12例中,2例单纯行CT平扫检查,4例单纯行CT增强检查,6例行CT平扫和增强检查。CT检查显示,病灶位于腹腔6例,盆腔2例,腹膜后4例;最大径均>6 cm,呈类圆形或分叶状,8例边界清楚;1例密度均匀,7例密度不均匀,6例见斑片状或条片状低密度区。增强扫描显示,9例动脉期呈不均匀强化,静脉期和延迟期持续强化;8例动脉期可见迂曲走行血管影和(或)周边有血管环绕。CT平扫显示的斑片状低密度区增强扫描无强化,病理上对应为囊变、坏死区;条片状低密度区增强扫描呈轻度延迟强化,病理上对应为富含纤维区域。
结论 腹部SFT的CT表现较有特征性,平扫包块内低密度区增强后无强化或呈轻度延迟强化,强化方式为“快进慢出”型,有助于对该肿瘤的诊断。
Abstract:
Objective  To investigate the CT features of abdominal solitary fibrous tumor (SFT).
Methods  A retrospective analysis was performed for the CT findings and pathological manifestations of 12 patients with pathologically confirmed abdominal SFT.
Results  Among the 12 patients with SFT, 2 underwent CT plain scan alone, 4 underwent contrast-enhanced CT scan alone, and 6 underwent CT plain scan and contrast-enhanced CT scan. CT scan showed that 6 lesions were located in the abdominal cavity, 2 in the pelvic cavity, and 4 in the retroperitoneum. The maximum diameter of these lesions exceeded 6 cm and the lesions had an oval or lobular shape; eight of them had clear boundaries. CT plain scan showed that 1 lesion had homogeneous density,7 had heterogeneous density, among which 6 had patchy or striped low-density areas. Contrast-enhanced CT scan showed 9 lesions had inhomogeneous enhancement in arterial phase and continuous enhancement in venous phase and delayed phase, and 8 had the shadow of tortuous vessels and/or were surrounded by vessels. Patchy low-density areas on CT plain scan had no enhancement on contrast-enhanced CT scan and were considered cystic or necrotic areas in pathology; striped low-density areas had mild delayed enhancement and were considered rich in fibers in pathology.
Conclusion  Abdominal SFT has unique CT features. Low-density areas on CT plain scan show no enhancement or mild delayed enhancement on contrast-enhanced CT scan, and the enhancement mode is “fast forward and slow out”, which may help with the diagnosis of this tumor.
