软组织侵袭性脂肪瘤少见,其中少数可侵犯椎管。本文报告2例经手术病理证实的累及椎管的侵袭性脂肪瘤。 例1:男性,8岁。发现有颈肩部肿块3年逐渐增大而在外院行手术。病理为‘脂肪瘤’。术后3个月局部肿块复发,生长迅速而来本院就诊。MRI见右颈部9.6×10cm不规则异常信号,T_1W高信号,T_2W中等信号。STIR序列上呈低信号。肿块边界清,呈侵润性生 Invasive lipomas of soft tissue are rare, and a few of them can invade the spinal canal. This article reports 2 cases of invasive lipomas involving the spinal canal confirmed by pathology. Example 1: Male, 8 years old. A neck and shoulder mass was found to have gradually increased for 3 years and surgery was performed in the external hospital. The pathology is ’lipoma’. Three months after the recurrence of local masses, rapid growth came to the hospital. On the MRI, 9.6 x 10 cm abnormal signals of the right neck, T_1W high signal, and T_2W moderate signal were observed. There is a low signal on the STIR sequence. Clear mass borders, invasive
