ROENTGENOLOGIC MANIFESTATIONS OF NON-NEOPLASTIC LESIONS OF THE SMALL INTESTINE

My purpose in this paper is to discuss the roentgenologic manifestations of the more commonly encountered non-neoplastic diseases of the small intestine. There is not a great variety of such processes. Peptic ulcer of the duodenum and of the jejunum occurring after gastro-enterostomy is omitted, because these parts are so intimately associated with the stomach that they are more properly considered in connection with lesions of that organ. Acute inflammatory processes of the small intestine are not included because patients afflicted with them rarely are, and probably never should be, submitted to roentgenologic examination. Syphilitic and actinomycotic lesions of the small intestine have been reported in the literature, but such lesions are so exceedingly rare that for practical purposes they may well be omitted from a discussion of this kind. The literature also contains reports of cases in which animal parasites, notably Ascaris lumbricoides, have been demonstrated in the small
