摘要
目的观察腹部恶性纤维组织细胞瘤(MFH)的CT表现。方法回顾性分析16例经病理证实的腹部MFH患者的临床、病理及影像学资料。结果所有患者均接受CT平扫及增强扫描。11例单发,5例多发;腹膜后7例,肠系膜4例,肝脏3例,十二指肠、肾脏各1例。CT平扫15例病变呈低密度,1例呈等密度。1例病灶内见颗粒状钙化灶,2例周边见大量条索影。增强扫描12例病变不均匀强化,2例均匀强化,2例肝内MFH未见强化,其内可见分隔。病理结果:多型性8例,炎症型2例,黏液型1例,未明确分型MFH 5例。结论腹部MFH缺乏特征性影像学表现,综合分析有助于术前诊断。
Objective To investigate CT appearances of primary abdominal malignant fibrous histiocytoma (MFH). Methods A retrospect analysis of clinical features, pathological data and CT characteristics of MFH confirmed by patholo- gy was performed in 16 patients. Results Abdominal MFH was observed in 16 patients with plain and enhanced CT exami- nation. The lesions located in retroperitoneum (n=7), mesentery (n=4), liver (n=3), duodenum (n= 1) or kidney (n= 1). Single lesion was found in 11 patients, while multiple lesions were searched in 5 patients. On plain CT, lesions showed as low attenuation density in 15 patients, as iso-density in 1 patient. Granular calcifications were seen in 1 patient, while a- mount of streak density around lesion were found in 2 patients. Contrast enhanced CT showed heterogeneous enhancement in 12 patients, homogeneous enhancement in 2 patients. Liver MFH with septa in 2 patients did not enhance. Pathological examination revealed MFH with storiform-pleomorphic variety in 8, with inflammatory variety in 2, with myxoid variety in 1 patient, as well as indefinite type MFH in 5 patients. Conclusion Abdominal MFH has no specific imaging findings. Comprehensive analysis contributes to preoperative diagnosis of MFH.
