侵袭性纤维瘤病的影像诊断价值

The Imaging Diagnosis of Aggressive Fibromatosis

目的探讨侵袭性纤维瘤病(AF)的影像诊断价值。方法回顾性分析经手术和病理证实的69例AF的CT和MRI表现。结果 14例腹壁型均为育龄期女性,腹外型及腹腔型男、女分别为27例、28例。CT上18例为均匀稍低密度,16例呈稍低-稍高混杂密度,增强后稍低密度区逐渐强化;46例MRI表现为等或稍长T1、稍长T2信号,伴有范围不等的短T2信号,增强后等或稍长T1、稍长T2信号区强化明显,短T2信号区轻微强化。结论AF的CT和MRI表现具有一定特征性,影像检查对该病的诊断和鉴别诊断有重要价值。

Objective To assess the value of imaging examination in diagnosing aggressive fibromatosis. Methods CT and MRI findings of 69 patients with pathologically-proved aggressive fibromatosis were retrospectively analyzed. Re- suits Abdominal wall type of aggressive fibromatosis was seen in 14 females in childbearing age, while extra-abdominal or intra-abdominal type of aggressive fibromatosis was seen in 27 females and 28 males. On CT scans, all the lesions showed homogeneous slight low-density （n = 18 ）, or inhomogeneous mild-lower or higher density （n = 16 ） with enhancement. In 46 cases, the lesions showed iso-intensity or slightly long T1 and slightly long T2 signal, with short T2 signals, which be- came obviously enhanced after the injection of contrast. Conclusion Aggressive fibromatosis has certain CT and MRI characteristics, which are very helpful in diagnosing and differentiating this disease.
