颈部淋巴结结核的CT表现与临床

CT Findings of the Cervical Tuberculous Lymphadenitis

目的:探讨颈部淋巴结结核的CT特征。方法:47例颈部淋巴结结核患者接受了CT平扫及增强扫描,对其所有CT图像进行回顾性分析。结果:根据病理学表现,颈部淋巴结结核的CT表现分为四型:I型:结核结节及肉芽肿形成5例;II型:淋巴结干酪样坏死18例;III型:淋巴结包膜坏死21例;IV型:淋巴结干酪样坏死破溃并向周围侵犯3例。结论:CT可较为准确反映颈部淋巴结的病理学变化,对于颈部淋巴结结核的诊断具有较高的价值。

Purpose: To investigate the CT findings of the cervical tuberculous lymphadenitis. Methods: Plain and con- trast-enhanced CT were performed in 47 cases with cervical tuberculous lymphadenitis confirmed by histopathology. All CT images were reviewed. Results: According to the histopathologic finding, CT findings of cervical tuberculous lymphadenitis were classified into four types: 5 cases were type I, tuberculers node and granuloma;18 cases were type II, lymphoglandula caseousnecrosis;21 cases were type III, peplos necrosis of the lymphoglandula;3 cases were type IV, diabrosis of the lymphoglandula caseousnecrosis and invaded the tissue surroundings. Conclusion: CT can demon-strate the pathological abnormalities of cervical tuberculous lymphadenitis and play an important role in the diagnosis of the disease.
