Lipoblastoma is a rare benign adipocytic tumour that usually occurs in children younger than 3 years, with male predominance. Lipoblastoma usually presents as a slowly enlarging soft tissue mass in the extremities although other sites of involvement have been reported. We report three cases of lipoblastoma in a lower limb with different magnetic resonance imaging features, some of which are shared by malignant soft tissue tumours.

脂肪母細胞瘤是一種良性脂肪細胞腫瘤,好發於三歲以下的兒童,男性患者居多。脂肪母細胞瘤大部分病變出現緩慢增大的軟組織包塊,四肢為最常累及的部位,也有發生於其他部位的報導。本文報告出現在下肢的脂肪母細胞瘤的三個病例,它們均有不同的磁共振成像表現,其中一些表現與惡性軟組織腫瘤相似。
