Lipomas are the most commonly encountered benign mesenchymal tumour, arising in any location where fat is normally present. Lipomas in the head and neck are rare in all age groups. Cases of vascular sheath lipomas in the femoral region have only been reported in adults. In children, vascular sheath lipomas have not been described to date. We report the first case of a carotid sheath lipoma in a seven-year-old boy. He had a non-tender soft mass with ill defined borders occupying the left upper part of the neck. Magnetic resonance imaging showed a mass at the bifurcation of the left common carotid artery without involving the same. The mass was hyperintense on T1 and T2 weighted sequences, suggestive of a lipoma. The lipoma was enucleated after incising the carotid sheath, safeguarding its contents. Histopathology confirmed it as a lipoma.
脂肪瘤是最常见的良性间叶组织肿瘤，可发生于任何正常存在脂肪的部位。头颈部脂肪瘤在所有年龄组中都很罕见。股部血管鞘脂肪瘤病例仅在成人中报道过。迄今为止，儿童血管鞘脂肪瘤尚未见报道。我们报告首例发生于一名7岁男孩的颈动脉鞘脂肪瘤。他有一个边界不清的非压痛性软肿块，占据颈部左上部。磁共振成像显示左颈总动脉分叉处有一个肿块，但未累及该动脉。该肿块在T1加权和T2加权序列上呈高信号，提示为脂肪瘤。在切开颈动脉鞘并保护其内容物后，将脂肪瘤摘除。组织病理学证实为脂肪瘤。
