颈部淋巴结结核的CT表现与临床

CT Findings of the Cervical Tuberculous Lymphadenitis

摘要: 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.
