Abstract

Calcifying aponeurotic fibroma (CAF) is a rare benign tumor that typically develops in the fascia and tendons. On MRI, CAF usually shows isointensity on T1WI and heterogeneous high intensity on T2WI. We report a case of 17-month-old girl with CAF on her right ankle. MRI showed an usual signal intensity for CAF. At 3 years and 4 months of age, MRI revealed hyperintense nodules on T1WI and T2WI inside of the CAF. These fatty areas corresponded to coarse calcified nodules on CT. Radiologists should be aware of the fact that fat-like signals can appear in CAF on MRI.

摘要

钙化性腱膜纤维瘤（CAF）是一种罕见的良性肿瘤，通常发生于筋膜和肌腱。在磁共振成像（MRI）上，CAF在T1加权像（T1WI）上通常呈等信号，在T2加权像（T2WI）上呈不均匀高信号。我们报告一例17个月大女童右踝部患有CAF的病例。MRI显示CAF具有常见的信号强度。在3岁4个月时，MRI显示CAF内部在T1WI和T2WI上有高信号结节。这些脂肪样区域在计算机断层扫描（CT）上对应粗大的钙化结节。放射科医生应注意CAF在MRI上可出现脂肪样信号这一事实。
