摘要
目的 :探讨CT在纵隔淋巴结肿大定性诊断中的价值。方法 :对 4 3例经手术、颈部淋巴结活检和临床治疗证实纵隔淋巴结肿大作了影像学分析。其中 ,男性 19例 ,女性 2 4例 ,年龄 19～ 4 5岁 ,平均为 32岁 ,全部病例作了胸部平片和CT扫描 ,其中 18例作了CT增强扫描。结果 :4 3例中转移性淋巴结肿大 16例 (肺癌 12例 ,乳腺癌 4例 ) ,结核 9例 ,恶性淋巴瘤 11例 ,结节病 4例 ,坏死性淋巴结炎 3例。而胸部平片仅发现纵隔增宽和肺内病灶 ,CT则在 4 3例中均能发现纵隔淋巴结增大的部位、数目、大小和形态。 18例CT增强扫描 ,转移性淋巴结肿大强化不明显 ,而结核性淋巴结肿大呈环形强化 ,淋巴瘤引起的淋巴结肿大略有强化 ,结节病引起的淋巴结肿大明显强化。结论 :CT扫描是诊断纵隔淋巴结大小的首选方法 ,根据病人临床表现 ,肺内病灶形态、CT平扫及CT增强扫描CT征象 ,对纵隔淋巴结肿大的定性诊断起着十分重要的作用。
Objective:To access the value of CT in the qualitative diagnosis of mediastinal lymphadenectasis.Methods:The imaging materials of 43 patients of mediastinal lymphadenectasis proved by operation, cervical lymph node biopsy and clinical treatment were analyzed.There were 19 men and 24 women,aged 19～45 years(mean=32 years). All the cases underwent chest radiographs and CT scans,18 cases underwent contrast enhanced CT scans.Results:Among 43 patients,there were 16 cases of metastaic lymph node enlargement(12 cases of lung cancer,4 cases of breast cancer),9 of tuberculosis;11 of malignant lymphoma,4 of sarcoidosis and 3 of necrotic lymphadenitis.Oh chest radiographs,only mediastinum widening and pulmonary lesions were shown.On CT films,the site,number,size and appearance of mediastinal lymphadenectasis were found in all cases.After contrast administration,the enhancement of lymph node showed minimal in metastasis, circle-like in tucerculosis,slight in lymhoma and distinct in sarcoidosis.Conclusion:CT scan was the first method to dignose the size of mediastinal lymph node and played an important role in the qualitative diagnosis of mediastinal lymphadenectasis according to the clinical manifestations,appearance of pulmonary lesion on CT films(plain and enhanced)
