Abdominal tuberculosis (TB) is the sixth most common extrapulmonary site of involvement. The sites of involvement in abdominal tuberculosis, in descending order of frequency, are lymph nodes, genitourinary tract, peritoneal cavity, and gastrointestinal tract. The radiological armamentarium for evaluating tuberculosis of the small bowel (SBTB) includes barium studies (small bowel follow-through, SBFT), CT (multidetector CT, CT enterography, and CT enteroclysis), ultrasound (sonoenteroclysis), and magnetic resonance imaging (MRI; enterography and enteroclysis). In this review, we illustrate the abnormalities at MDCT enterography in 20 consecutive patients with SB TB and also describe extraluminal findings in these patients. MDCT enterography allows non-invasive good-quality assessment of well-distended bowel loops and the adjacent soft tissues. It displays the thickness and enhancement of the entire bowel wall in all three planes and allows examination of all bowel loops, especially the ileal loops, which are mostly superimposed. The terminal ileum and ileocaecal junction are the most common sites of small bowel involvement in intestinal TB. The most common abnormality is short-segment strictures with symmetrical concentric mural thickening and homogeneous mural enhancement. Other findings include lymphadenopathy, ascites, enteroliths, peritoneal thickening, and enhancement. In conclusion, MDCT enterography is a comprehensive technique for the evaluation of SB TB.
腹部结核(TB)是第六大常见的肺外受累部位。腹部结核的受累部位按频率降序排列为淋巴结、泌尿生殖道、腹腔和胃肠道。评估小肠结核病(SBTB)的放射学手段包括钡剂研究(小肠造影,SBFT)、CT(多排 CT、CT 肠造影和 CT 肠灌洗)、超声(超声肠灌洗)和磁共振成像(MRI;肠造影和肠灌洗)。在这篇综述中,我们展示了 20 例连续 SB TB 患者的 MDCT 肠造影中的异常,并描述了这些患者的腔外表现。MDCT 肠造影允许对充分扩张的肠袢和相邻软组织进行非侵入性的高质量评估。它在所有三个平面上显示整个肠壁的厚度和增强,并允许检查所有肠袢,特别是大部分重叠的回肠袢。末端回肠和回盲部是肠结核中小肠受累的最常见部位。最常见的异常是短节段狭窄,伴有对称的同心性壁增厚和均匀的壁强化。其他发现包括淋巴结病、腹水、肠石、腹膜增厚和强化。总之,MDCT 肠造影是评估 SBTB 的综合技术。
