目的 对比病理结果分析，旨在 提高对颈外侧区良恶性病变MSCT诊断和鉴 别诊断认识。方法 回顾分析69例颈部病 变的病理结果及CT表现，对良恶性病灶的 边界不清、病灶融合、血供丰富、多发病 灶及环状强化情况进行统计分析。结果 恶性病变44例：淋巴结转移性癌32例，淋 巴瘤10例，恶性孤立性纤维性肿瘤1例， 颌下腺多形性腺瘤恶变1例；良性病变25 例：炎性病变16例，良性肿瘤5例，囊肿3 例，脂膜炎1例；颈部良恶性病变影像表 现，边界不清：恶性病变40例，良性病变 4例；病灶融合：恶性35例，良性7例；血 供丰富：恶性36例，良性13例；多发病 灶：恶性39例，良性13例；环状强化：恶 性18例，良性13例。结论 颈外侧区病变 以淋巴结转移性癌多见；CT较常见征象为 环状强化伴中央坏死，但良恶性病变其病 理基础不同；边界不清及病灶融合可作为 良恶性鉴别诊断的参考依据，而病变要准 确定性则需结合临床资料及最终依靠病理 和免疫组化。

Objective Comparative pathological analysis,Objective to improve the diagnosis and differential diagnosis of benign and malignant lesion MSCT. Methods The pathological results and CT findings of 69 cases of neck lesions were retrospectively analyzed. The borderline of benign and malignant lesions, fusion of lesions, rich blood supply, multiple lesions and Ring to strengthen were analyzed. Results 44 cases of Malignant lesions. There were 32 cases of lymph node metastatic carcinoma and 10 cases of lymphoma,1 case of malignant solitary fibrous tumor, 1 case of malignant transformation of pleomorphic adenoma of the submandibular gland. 25 cases of benign lesions. There were 16 cases of inflammatory disease, 5 cases of benign tumor, 3 cases of cyst and 1 case of panniculitis. Image performance of benign and malignant cervical lesions. Borderline:40 cases of malignant lesions, 4 cases of benign lesions. Lesion fusion:35 cases of malignant lesions, 7 cases of benign lesions, rich blood supply:36 cases were malignant lesions and 13 were benign lesions. Multiple lesions: 39 cases malignant lesions and 13 benign lesions. Ring to strengthen: malignant lesions 18 cases, benign lesions 13 cases. Conclusion The lesion in the lateral area of the neck was frequently seen with lymph node metastatic carcinoma. CT is more commonly seen as annular enhancement with central necrosis. However, the pathological basis of benign and malignant lesions is different. Boundary ambiguity and lesion fusion can be used as a reference for benign and malignant differential diagnosis. In order to accurately determine the lesion, it is necessary to combine clinical data and ultimately rely on pathology and immunohistochemistry.
