Lipoblastoma is an uncommon benign lipomatous soft tissue mass of childhood, occurring most commonly in children less than 3 years of age. We present a case of lipoblastoma occurring in the foot of a 14-year-old boy and review the literature. The appearance of the mass on magnetic resonance imaging (MRI) is illustrated and is correlated with the findings at gross and microscopic pathological examination. A lobulated architecture, the presence of adipose tissue, thin nonenhancing septa, peripheral lobules of more immature and therefore less specific tissue, and a peripheral pseudocapsule were evident on MRI and at pathological examination.
脂肪母细胞瘤是一种儿童期罕见的良性脂肪瘤性软组织肿块，最常见于3岁以下儿童。我们报告一例发生在一名14岁男孩足部的脂肪母细胞瘤病例并复习相关文献。文中展示了该肿块的磁共振成像（MRI）表现，并将其与大体及显微镜下病理检查结果相关联。在MRI及病理检查中均可见分叶状结构、脂肪组织的存在、薄的无强化间隔、周边为更不成熟因而特异性较低的组织小叶以及周边假包膜。
