 To present sufficient causes for the rarity of a certain disorder is a difficult task. The first reason for this is the lack of a database for these disorders. The second reason is that rare disorders have a tendency to concentrate to special facilities. This article deals with the rare, non-tumorous, benign disorders of the large intestine. The disorders were first divided into two categories:inflammatory and noninflammatory. Further classification was according to the pathophysiology. Among the disorders that the authors consider rare, those with characteristic findings in imaging were selected and explanations were added for the same. However, it should be understood that the list of rare disorders may not reflect the real incidences.
