[Angiographic signs of the small intestine (two cases) (author's transl)].

The authors describe 2 cases of ileal carcinoid. They evaluate the advantages of selective angiography over the traditional radiologic methods, considering their cases and the 39 found in the literature. The angiographic signs of the lesions localized to the bowel wall are rather scarse and non-specific. The signs of mesenteric infiltration, which is precocious and conspicuous in this type of tumour, are more significant. Liver metastases, which are very frequent, are hypervascularized. The angiographic pattern may be similar to that found in some inflammatory diseases, but can be differentiated from that of other neoplasms of the small intestine.
