摘要
目的 分析侵袭性纤维瘤病的CT表现 ,了解其影像特征。资料与方法 回顾性分析经手术及病理证实的侵袭性纤维瘤病 13例 ,原发 8例 ,复发 5例。颅面部肿物 2例 (15 .4 % ) ,颈胸部肿瘤 6例 (46 .1% ) ,腹部肿瘤 5例(38.5 % ) ,包括前腹壁肿瘤 4例 (30 .8% ) ,腹膜后肿瘤 1例 (7.7% )。结果 颈胸部侵袭性纤维瘤病 6例 ,男 3例 ,女 3例 ,初次发病年龄 13～ 36岁 ,2 0～ 4 0岁占 83%。肿瘤沿肌肉长轴生长 ,边缘不规则 ,范围广泛 ,肿瘤明显侵犯周围肌肉、骨骼、纵隔等结构。 5例为增强扫描 ,肿瘤强化程度略高于肌肉 ,4例肿瘤内有不规则低密度区。腹壁侵袭性纤维瘤病 4例 ,均为女性 ,初次发病年龄 2 3～ 5 2岁 ,2 0～ 30岁者占 75 %。肿瘤截面为梭形或卵圆形 ,沿腹直肌和 /或腹斜肌长轴生长 ,边缘规则 ,密度基本均匀 ,平扫或增强扫描密度接近于周围肌肉密度。结论 发生于颈胸部及腹壁的侵袭性纤维瘤病CT表现及发病年龄有一定特征 。
Objective To clarify the CT characteristics of aggressive fibromatosis.Materials and Methods CT findings and clinical manifestations in 13 patients with pathologically proved fibromatosis (primary 8 cases, recurrent 5 cases) were retrospectively analyzed. The lesions in this study included cervico thoracic aggressive fibromatosis (n=6, 46.1%), abdominal wall aggressive fibromatosis (n=4, 30.8%), retroperitoneal aggressive fibromatosis (n=1, 7.7%) and craniofacial aggressive fibromatosis (n=2, 15.4%).Results Cervico thoracic aggressive fibromatosis (3 males and 3 females, aged 13～36 years) tended to grow along the long axis of muscles and infiltrated neighboring structures. Enhanced CT scan was carried out in 5 cases. The enhancement degree of the lesion was a little bit higher than the muscles, and irregular low density area within the mass was seen in 4 cases. The 4 cases of abdominal wall aggressive fibromatosis were all females, aged 23～52 years. The sectional shape of the lesion was elliptic or ovoid. The tumor grew and infiltrated along the abdominal wall muscles.Conclusion Aggressive fibromatosis at cervico thoracic region and abdominal wall has certain CT characteristics and predilection age, CT scanning is helpful for its diagnosis and for the evaluation of the tumor extent.
