Nevus lipomatosus cutaneous superficialis is a rare disease, and its magnetic resonance imaging features have not been reported. A 1-year-old male infant was admitted to our hospital for examination of a mass on his right shoulder. Magnetic resonance imaging revealed hypertrophic skin and a lipomatous subcutaneous mass, consistent with a hamartoma-like lesion or mesenchymal tumor; after surgery, the tumor was pathologically diagnosed as nevus lipomatosus cutaneous superficialis. To the best of our knowledge, this is the first case report focusing on the magnetic resonance imaging features of this disease. Hypertrophy of all skin structures involved (epidermis, dermis, and subcutaneous fat) may be specific to nevus lipomatosus cutaneous superficialis, enabling its differentiation from other tumors.
浅表性皮肤脂肪瘤痣是一种罕见疾病，其磁共振成像特征尚未见报道。一名1岁男婴因右肩部肿物入院检查。磁共振成像显示皮肤肥厚及皮下脂肪瘤样肿物，符合错构瘤样病变或间叶性肿瘤；术后肿瘤经病理诊断为浅表性皮肤脂肪瘤痣。据我们所知，这是首例关注该疾病磁共振成像特征的病例报告。所有受累皮肤结构（表皮、真皮和皮下脂肪）的肥厚可能是浅表性皮肤脂肪瘤痣所特有的，有助于将其与其他肿瘤相鉴别。
