Lipoblastoma is a rare and benign tumour arising from embryonal fat cells, predominantly diagnosed in children younger than 3 years old. The most frequent locations are the extremities and trunk, while the head and neck areas are more rarely affected (10-15% of total cases). Clinically, the most common presentation is a fast-growing painless mass. Ultrasound is the first-line imaging examination, but Magnetic Resonance Imaging (MRI) allows for better definition of the relationships with the adjacent vascular and muscular structures. It can help to identify the lipomatous components, and it is useful for preoperative planning. However, the definitive diagnosis is provided by histopathological examination. Complete surgical excision is the first-line treatment, with a good prognosis in case of total eradication. We report the case of a 7-month-old male child with a rapidly growing mass that had typical radiological features of lipoblastoma.
脂肪母细胞瘤是一种罕见的良性肿瘤，起源于胚胎脂肪细胞，主要发生于 3 岁以下的儿童。最常见的部位是四肢和躯干，而头颈部则较少受累（占所有病例的 10-15%）。临床上，最常见的表现是快速生长的无痛性肿块。超声是首选的影像学检查，但磁共振成像（MRI）可以更好地显示与相邻血管和肌肉结构的关系。它有助于识别脂肪瘤成分，并有助于术前规划。然而，明确的诊断需要通过组织病理学检查。完整的手术切除是一线治疗方法，如果能完全切除，预后良好。我们报告了一例 7 个月大的男性患儿，其快速生长的肿块具有脂肪母细胞瘤的典型影像学特征。
