1 病例简介患者女性,67岁,左颈部肿物伴疼痛及张口受限1个月余.体格检查:左颈部明显肿胀,可触及直径约1.0cm肿物,活动度较差,轻度压痛.CT表现:CT横断面平扫示腮腺深叶可见约3.5cm×4.4cm× 5.5cm大小的软组织肿块,边缘不规则,其内密度不均匀,可见斑片状低密度影及斑点状钙化(图1),增强扫描后肿物可见持续不均匀强化(图2),左侧颈外动脉及其分支被推挤向前、外,左侧翼内肌肿胀,且与肿物分界不清,左颞下颌关节受推挤、关节对位差,左颈部可见多发软组织结节影.CT影像诊断:左颈部占位,性质多考虑为恶性,来源于腮腺深叶可能性大. 相似文献

女,48岁。5个月前,无意中发现左侧颌下有一肿物,如枣核大小。曾行抗炎治疗,后肿物有所减小。但近5个月来肿物逐渐增大。查体:左侧下颌稍大于右侧,左侧颌下可触及一肿物,大小约5cm×5cm,稍压痛、固定无活动感;颈两侧无畸形,无颈静脉怒张及颈动脉异常搏动,软、无抵抗,气管居中,甲状腺不大。CT显示:左颌下有一5cm×5cm肿物,强化后边缘密度高,中心密度低(图1,2)。临床诊断:左腮腺瘤,予以手术治疗。术中见左腮腺区有一约3cm×3cm×2cm大小肿物,与腮腺后叶分界不清,位于面神经分支下侧,予以完整切除。病理诊断:腮腺黏液表皮样癌。讨论:黏液表皮样… 相似文献

We report a large sebaceous adenoma of the parotid gland. CT showed soft-tissue mass in the lateral portion of the adenoma corresponding to the histologic finding of proliferation of sebaceous glands and fibrous stromal tissue. There were numerous fatty cysts (-65Hu). Some of the cystic component ruptured, and CT demonstrated leaking of fatty material into the parapharyngeal space. 相似文献

We present the case of an elderly woman with a painless giant tumor of the neck. Computed tomography (CT) demonstrated a cyst-like lesion that appeared to arise from the parotid gland. The tumor was removed in toto and histopathologically diagnosed as an epithelial–myoepithelial carcinoma. Such rare carcinomas should be considered in the differential diagnosis of parotid gland malignancies. We discuss the possibilities of imaging modalities such as CT and magnetic resonance imaging (MRI) in the differentiation between benign and malignant salivary gland tumors. 相似文献

We describe an unusual salivary neoplasm, an epithelial-myoepithelial carcinoma (EMEC) of the parotid gland, that occurred in a 64-year-old man. A CT scan showed a fairly well defined heterogeneous lesion with smooth margins and slight enhancement. MR images showed a lesion with intermediate T1-weighted signal intensity and a relatively high T2-weighted signal intensity. Although the imaging characteristics of EMEC on both CT and MR studies are nonspecific, clinicians and radiologists must be aware of its high local recurrence rate, which has been reported to approach 50% in some series, and thus the need for periodic postoperative imaging to detect early recurrence. 相似文献
