To provide an overview of less well-known small bowel and mesenteric diseases found at small bowel magnetic resonance (MR) enterography/enteroclysis and to review the imaging findings. MR enterography and enteroclysis are important techniques for evaluation of small bowel diseases. In most centres these techniques are primarily used in Crohn's disease, and most radiologists are familiar with these MRI findings. However, the knowledge of findings in other diseases is often sparse, including diseases that may cause similar clinical symptoms to those of Crohn's disease.
We present a spectrum of less common and less well-known bowel and mesenteric diseases (e.g. internal hernia, intussusception, neuroendocrine tumour) from our small bowel MR database of over 2,000 cases.
These diseases can be found in patients referred for bowel obstruction, abdominal pain or rectal blood loss. Further, in patients with (or suspected to have) Crohn's disease, some of these diseases (e.g. neuroendocrine tumour, familial Mediterranean fever) may mislead radiologists to erroneously diagnose active Crohn's disease.
Radiologists should be familiar with diseases affecting the small bowel other than Crohn's disease, including diseases that may mimic Crohn's disease.
介绍在小肠磁共振（MR）肠造影/肠灌洗中发现的一些不太常见的小肠和肠系膜疾病，并复习其影像学表现。MR 肠造影和肠灌洗是评估小肠疾病的重要技术。在大多数中心，这些技术主要用于克罗恩病，大多数放射科医生都熟悉这些 MRI 发现。然而，对于其他疾病的表现，知识往往很匮乏，包括可能引起与克罗恩病相似临床症状的疾病。
我们从 2000 多例小肠 MR 数据库中展示了一系列不太常见和不太知名的肠道和肠系膜疾病（如内疝、肠套叠、神经内分泌肿瘤）。
这些疾病可发生于因肠梗阻、腹痛或直肠出血而就诊的患者中。此外，在（或疑似患有）克罗恩病的患者中，这些疾病中的一些（如神经内分泌肿瘤、家族性地中海热）可能会误导放射科医生错误地诊断为活动性克罗恩病。
放射科医生应熟悉除克罗恩病以外影响小肠的疾病，包括可能模拟克罗恩病的疾病。
