Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis.
腹部结核的放射学表现可与许多不同疾病的表现相似。需要高度怀疑，尤其是在高危人群中。在本文中，我们将描述腹部结核的钡剂造影、超声（US）和计算机断层扫描（CT）表现，重点介绍最新的情况。我们将阐述有助于腹部结核诊断的CT表现，并描述将其与其他炎症性和肿瘤性疾病（特别是淋巴瘤和克罗恩病）相鉴别的影像学特征。由于结核可累及腹部的任何器官，故重点关注回盲部受累、淋巴结病、腹膜炎和实性器官疾病（肝脏、脾脏和胰腺）。许多患者仍需要活检的培养结果呈阳性或组织学分析结果才能确诊。
