目的分析侵袭性纤维瘤病的 CT 和 MR 表现,了解其影像特征.资料与方法回顾性分析经病理证实的17例侵袭性纤维瘤病患者的 CT 和 MR 表现.结果17例患者中14例行 CT 检查,7例行 MR 检查,4例同时行 CT 及 MR 检查.行 CT 检查的14例患者中,CT 平扫12例呈不均匀低密度,2例呈较均匀低密度;边界清楚3例,边界不清11例.10例具有明显的爪形和分叶状形态.5例CT 增强检查均有不均匀强化.行 MR 检查的 7例患者,T1WI、T2WI、脂肪抑制序列肿瘤均为不均匀信号,肿块内有部分区域各序列均为低信号,4例肿块边缘呈爪形浸润,3例边缘不清.MR 增强 2例均呈不均匀强化.结论 CT 和MR 都能较好地显示侵袭性纤维瘤病的形态.MR 的信号特点可以推断肿瘤的成分.MR 比 CT 能更精确地显示病灶的形态和范围,对侵袭性纤维瘤病的诊断和鉴别诊断有重要价值.

Purpose To explore the CT and MR findings of aggressive fibromatosis. Materials and Methods CT and MR manifestations of seventeen patients with pathology proven aggressive fibromatosis, fourteen cases underwent CT, seven underwent MRI, four underwent both CT and MRI. Results Fourteen were identified by CT, of which twelve showed slight heterogeneous hypodensity, and two showed homogeneous hypodensity on NECT. Three cases had well-defined margins, while eleven had ill-defined margins. Ten cases had apparent claw-shaped or lobulated contour. Five cases showed heterogeneous enhancement following contrast injection. Seven tumors identified by MR appeared heterogeneous hypointensity or hyperintensity on T1WI, T2WI and T2WI with fat saturation. Low signal areas of the lesions were found on three sequences. Four tumors had claw-shaped margin, and 3 had ill-defined margin. Two cases showed heterogeneous enhancement following contrast injection. Conclusion Both CT and MR can accurately identify aggressive fibromatosis. MR can further evaluate the content of the tumors and is better in delineating the shape and extent of the lesions.
