A 47-year-old man had aggressive fibromatosis, and CT and MR showed a large, multilobulated soft-tissue mass within the prevertebral and retropharyngeal spaces. On CT, the lesion was slightly higher in attenuation than adjacent muscle; on MR, it was intermediate between muscle and fat on unenhanced T1-weighted images, isointense with fat on intermediate-weighted images, hyperintense relative to fat on T2-weighted images, and markedly enhanced after administration of gadopentetate dimeglumine. Multiple small focal and linear areas of decreased signal intensity that did not enhance with gadopentetate dimeglumine were observed on all pulse sequences.
一名47岁男性患有侵袭性纤维瘤病，CT和MR显示在椎前间隙和咽后间隙内有一个大的、多叶状软组织肿块。CT上，该病变的密度略高于相邻肌肉；MR上，在未增强的T1加权图像上其信号介于肌肉和脂肪之间，在中等加权图像上与脂肪等信号，在T2加权图像上相对于脂肪呈高信号，注射钆喷酸葡胺后明显强化。在所有脉冲序列上均观察到多个小的局灶性和线性信号强度减低区，注射钆喷酸葡胺后无强化。
