Crohn's disease (CD) is an increasingly common disease in clinical practice. The progress of medicine, which has resulted in an extension of the survival time of patients, the introduction of new treatment methods, and the nature of the disease itself means that we are seeing more and more new, unusual complications of this disease. We have reviewed three cases of rare complications of CD, with a focus on possible atypical complications that may be seen on imaging studies. Complications of CD and its treatment can occur in various organs and systems, and manifest in very non-specific ways. If unnoticed, they can be even life-threatening; therefore, it is important in clinical practice to take into account the possibility of their presence when evaluating patients with CD. When assessing radiological examinations of these people, we should take into account the possibility of atypical signs and radiographic features, and consider whether they may be related to the underlying disease.
