結核病能在身體的許多器官中造成感染，它在影像學上也可以有各種不同的呈現方式，有時甚至會模仿成類似惡性疾病的影像，因而造成臨床醫師判斷上的困擾。我們在此報告了此方面的一個特殊病患。一位60歲的女性病患，本身有糖尿病病患，咳嗽已經有兩年了，她的胸部電腦斷層顯示肋膜上有許多結節且有胸部縱膈腔淋巴結病變以及多發性肝臟腫塊。一開始我們以為這是惡性疾病併轉移的病例，但經過一系列的檢查後，才發現這是結核菌感染所造成。由於結核病在影像上多樣化的表現，我們建議臨床醫師，在病人本身的慢性疾病為結核病的好發因子時，要將結核病感染列為考慮的鑑別診斷之一。

Tuberculosis can involve many organs and have a broad spectrum of image presentation. It may resemble malignant diseases and thus confuse the judgment of the clinician. We report a 60-year-old diabetic woman suffered from chronic cough for 2 years and whose computed tomography scan revealed multiple pleural nodules with mediastinal lymphadenopathy and multiple liver masses. We approached this case as malignant disease initially but found it to be a systemic tuberculosis infection after a series of examinations. Tuberculosis may have radiological presentation like malignant disease. Physicians should consider tuberculosis as a possibility for those patients with underlying diseases, which can potentiate tuberculosis infection.
