摘要
目的探讨腹部滤泡树突状细胞肉瘤(FDCS)的CT特点,以提高对该病的认识和影像诊断水平。方法回顾性分析10例经手术及病理证实的FDCS患者术前CT表现及临床资料。结果10例患者中,男6例,女4例,年龄23~70岁,平均50.1岁。6例单发,4例多发;肿瘤平均最大长径为10.9 cm(3.5~19.3 cm)。CT平扫多表现为密度不均匀软组织肿块,边界清楚,9例病灶内可见坏死,4例病灶见粗大钙化。CT增强扫描8例患者病灶实性成分明显强化,2例病灶实性成分呈中度强化。结论腹部FDCS CT表现有一定特征性,当腹部单发或多发巨大软组织肿块出现内部坏死及钙化,增强扫描后肿瘤实性成分动脉期明显强化或渐进性强化时,应考虑到FDCS的可能。但确诊仍需依靠病理检查。
Objective To investigate the CT features of abdominal follicular dendritic cell sarcoma in order to improve the understanding and imaging diagnosis of the disease.Methods The CT findings and clinical data of 10 patients with follicular dendritic cell sarcoma confirmed by pathology were retrospectively analyzed.Results Among the 10 patients,6 were male and 4 female;the average age was 50.1 years(23-70 years).6 cases were single lesion,4 cases were multiple;the average maximum length of the tumor was 10.9 cm(3.5~19.3 cm).CT plain scan showed a soft tissue mass with heterogeneous density and well-defined margin.Necrosis was observed in 9 cases and coarse calcification was seen in 4 cases.CT enhancement scan showed that the solid components of the lesions were significantly enhanced in 8 cases,and the solid components of the lesions were moderately enhancement in 2 cases.Conclusion CT manifestations of abdominal follicular dendritic cell sarcoma have certain characteristics.When there is internal necrosis and calcification in single or multiple large soft tissue masses in the abdomen,and there is avid enhancement of the solid components of the tumor in the arterial phase or there was progressive enhancement,we should consider the possibility of follicular dendritic cell sarcoma.However,the definitive diagnosis is still dependant on pathological examination.
