[Radiological techniques for locating intrauterine device (author's transl)]. / Techniques radiologiques de localisation d'un dispositif intra-utérin.

PIP: A radiological method for the localization of intrauterine devices is suggested. The 1st step consists of taking a picture without any preparation, of the pelvic cavity. If there is no IUD is this area, one will obtain a picture of the whole abdomen. If the IUD is located in the pelvis, a traction on the cervix will most often allow to determine the intrauterine location of the device. In some cases, one has to perform a fractionated hysterography. The method gives the most reliable results. It is a very simple procedure which in most cases only necessitates 2 pictures and generally allows to avoid an hysterography. The echotomography is a more sophisticated procedure which generally allows the localization of the IUD. Other techniques include the double contrast hysterography and the pneumo-hysterography; these procedures however are rarely used.^ieng

[Pseudo-polypoid forms of crohn's disease (author's transl)]. / Les formes pseudo-polypoïdes de la maladie de Crohn.

Crohn's disease with a predominantly pseudopolypoid presentation is a rare form. The inflammatory polyps are of highly variable topography. They may be located in the colon and the ileum. There are diffuse and localised forms. This pseudopolypoid form of Crohn's disease poses, in addition to diagnostic problems, pathogenic questions, integrating these findings within the context of nonspecific reactions of the colon, secondary to an ulcerating process which may be specific.

[Atypical angiographic appearances of aneurisms of the abdominal aorta (author's transl)]. / Séméiologie angiographique atypique des anévrismes de l'aorte abdominale. A propos de 12 observations

On the basis of 72 radio-surgical cases of abdominal aortic aneurism, the authors stress the value of atypical angiographic findings, which are ten in number. The presence of clot within the aneurism itself may explain a disparity between radiological and surgical findings. Failure to recognize these atypical signs is very serious, when the diagnosis of aneurism is not suspected clinically. Antero-posterior and, above all, lateral abdominal aortography is essential in the angiographic study of aneurisms of the abdominal aorta. Careful search for these 10 atypical signs should make it possible to avoid missing latent aneurisms. Lateral abdominal aortography is essential in order to determine the state of the abdominal collaterals of the aorta and, in particular, the superior mesenteric artery.
