The Importance of the Roentgen Examination in the Diagnosis of Regional Ileitis

Author and Disclosure Information


Regional ileitis is a condition of unknown etiology which has been recognized for many years, although it did not receive the attention it deserved until the report of Crohn et al in 19321 . At that time they reported a series of cases to which they applied the term regional ileitis, since the condition was thought to be a disease entity involving only the terminal segment of the ileum. Since that time, however, cases have been seen in which not only the terminal ileum but other parts of the small bowel, as well as the cecum were involved. Indeed, it is not uncommon for several segments of the small intestine to show the changes typical of this disease with areas of normal bowel intervening. The term used to describe this condition is, therefore, not entirely satisfactory, a better and more descriptive term such as non-specific granulomata of the intestine being preferable. It is doubtful, however, whether this will supersede the original appellation, since it has come to have a definite meaning.

Regional ileitis, while not common, occurs frequently enough that one should think of it when a patient complains of symptoms in the lower right abdominal quadrant. This is especially true in a young adult male because the greatest incidence occurs in this sex at this age period. The following case presents a rather typical picture of the disease and emphasizes the value of the roentgen examination in establishing the diagnosis.
