Over the past 7 years, nine fatty tumors within the parotid gland have been managed (eight lipomas, one liposarcoma). High-resolution computed tomography examination was carried out in all cases; with correct preoperative diagnosis recorded each time. The computed tomography imaging characteristics of lipoma, liposarcoma, and the differential diagnosis from other fat density lesions, such as a fatty infiltration, appear quite specific. The liposarcoma and six of the lipomas were resected at formal parotidectomy with facial nerve preservation. Two patients with small intraglandular lipomas have elected to undergo long-term clinical and imaging observation. Our experience indicates that high-resolution, soft-tissue imaging with computed tomography and magnetic resonance imaging permits consistent preoperative fatty tumor diagnosis. This imaging input facilitates rational treatment decision-making.
在过去7年里，我们处理了9例腮腺内的脂肪性肿瘤（8例脂肪瘤，1例脂肪肉瘤）。所有病例均进行了高分辨率计算机断层扫描检查；每次术前诊断均正确。脂肪瘤、脂肪肉瘤的计算机断层扫描成像特征以及与其他脂肪密度病变（如脂肪浸润）的鉴别诊断似乎颇具特异性。1例脂肪肉瘤和6例脂肪瘤在保留面神经的情况下接受了腮腺全切术。2例腺内小脂肪瘤患者选择进行长期临床及影像学观察。我们的经验表明，计算机断层扫描和磁共振成像的高分辨率软组织成像能够实现脂肪性肿瘤的术前一致性诊断。这种影像学信息有助于做出合理的治疗决策。
