图1A～C：示右侧腮腺浅叶呈等稍长T1、长T2信号，边缘有短T2信号包膜，局部包膜不完整，DWI呈高信号，并伴有同侧颈部淋巴结转移；D：增强扫描病灶呈不均轻度强化；E：高倍镜下，见肿瘤细胞呈巢团状生长，细胞核大、深染(HE ×100)
Fig. 1A—C: Shallow lobes of her right parotid gland, slightly long T1 and long T2 signals, such as edge short T2 signal envelope, local coated incomplete, DWI has high signal, accompanied by ipsilateral neck lymph node metastasis. D: Uneven enhancement scan is mild. E: At high magnif i cation, tumor cell nests grow, the nuclei are large, deep dyeing (HE ×100).

患者 男，51岁，右侧耳前无痛性肿物渐进增大10年余，右侧颌下出现肿物3个月余。专科查体：右侧耳前腮腺区域可触及一约4.0 cm×3.5 cm大小类圆形肿物，质地中等偏硬，活动度尚可，边界尚清，无明显触压痛，表面皮肤颜色正常。右侧下颌角下方可触及一约3.5 cm×3.0 cm大小的肿物，质地较硬，边界清楚，活动度尚可，与周围组织无明显粘连，表面皮肤颜色正常，右侧颈部上份斜方肌前缘区域可触及浅表散在肿大淋巴结3枚，肿大淋巴结为0.6 cm×0.4 cm大小，边界清楚，质硬，活动好。MRI检查：右侧腮腺内见一不规则形异常肿块影，呈多分叶状混杂长T1、短T2信号，边缘可见短T2信号包膜，局部与腮腺分界不清，DWI呈不均匀等、高信号，边界尚清，内可见多发囊泡状短T1、长T2信号影，增强扫描病灶呈不均匀强化。MRI诊断：右侧腮腺浅叶肿块影，多考虑恶性肿瘤性病变并双侧颌下及颈部多发肿大淋巴结影，恶性混合瘤并出血可能。……
