This appearance is made by precise adaptation of the opaque colonic mucosa depressed in the form of a "cupola" over the intraparietal gas bubble which results in the deformity. Endoscopy failed to reveal the disorder in the case reported here.

The improvement in the quality of radiological diagnosis by the use of double contrast study of the small bowel after duodenal intubation is emphasised. On the basis of this case, together with a review of the literature, they review the various problems of diagnosis, physiopathology and histology which may be posed by these stenoses, which it would seem possible to integrate into a wider physiopathological group: ischaemic stenoses of the digestive tract.

The authors report here a case which is exceptional in the sense that the azygos prolongation was isolated. Further radiological studies are essential in order to make the diagnosis following the discovery of a right-sided laterotracheal opacity on a plain chest film. Only five other cases were found in the literature.

Bronchoscopy with broncho-aspiration provided histological confirmation of the diagnosis of broncho-alveolar spread of the papillomatosis, made on the basis of plain films and tomography.

A "thumbprint" appearance of lacunae 2 to 4 mm in diameter, in substraction in relation to the wall of the colon, diffuse involvement of the colon and the regression of these signs when antibiotics are stopped are the typical radiological signs of this disorder.

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.

None of these various phases in study may suffice to eliminate the possibility of an associated carcinoma. The diagnosis may be made by opening the operative specimen, but this is too late in time. The appearance of the bladder, rather than misleading the diagnosis, may provide arguments in favour of the benign nature of these pseudo-tumours.

The diagnosis of carcinoma could be affirmed in the very great majority of cases and suspected in the others. 2. There were no instances of a reassuring false diagnosis (cyst). 3. A precise, rigourous and faultless technique, perfectly demonstrating the exteriorised part of the mass and attentive, thorough and careful interpretation of the films obtained, in particular with regard to the mass in its exteriorised portion, are always essential in order to obtain such results. In particular, the presence of a vascularisation of a discontinuous opaque band at the periphery of the mass in its exteriorised part indicates a strong suspicion of a necrotic malignancy and under no circumstances is an unreserved diagnosis of a cyst possible. 4. Diagnostic errors in the sense of false positives involving certain "thick-walled" cysts should be eliminated by pre-operative needle puncture. 5. The authors conclude by describing the method of radiological exploration which they feel to be desirable in practice following the discovery of a renal mass by intravenous pyelography.

It should be incorporated in any echotomographic study of the hepatic parenchyma and reciprocally. This method of investigation is harmless, rapid, reproducible and low in cost.

T.). A critical analysis of the method is made, based upon the diagnostic results obtained as well as the errors and gaps noted. After describing the normal liver, the authors give the "C. T. appearances" of the main hepatic conditions, based upon correlation with macroscopic pathological findings.

A statistical blind study of 330 cases shows that only well definite syndroms are reliable. The presence of absence of a single sign has no value. Difficulties arise in the diagnosis of suspect nodule in a dense dystrophic breast. Hydratation of the connecting tissue is a fundamental concept for analysis of mammographic pictures. The densities change according to hormonal influence, growth of dystrophy and specific signs of fibrillary or hyalin fibrosis. A histological study of serial cuts of the breast shows that the must reliable signs are found in the center of the nodule ande immediately around it. As in the histological study, serial cuts are indispensable in X-ray examination. Tomography improves the examination of dystrophies.

This condition is found usually in the man of the fifties who has most frequently an urinary tract infection or a prostatic adenoma. The roentgen findings are multiple out-poutchings of the lumbar ureter. Several factors are combined (constitutionnal, urinary tract infection, disordered ureteral-motility) to explain the creation of diverticules in the areas of weakness of ureteral wall, where penetrate the vessels.

The impossibility of a direct reading is a major drawback of reproduction in the form of slides. By contrast, a transparency is an irreplaceable teaching tool. Contact printing of slides on counterpart film is a process within the reach of all departments of radiology. In one single step, this process gives a plate of 100 transparencies on counterpart film costing about 2.20 dollars.

The values which have been adopted after a very large clinical experience are the following: --reference dose: 6000 rads (N.S.D. 1760). --surface dose: 8400 rads (N.S.D. 2200). The choice of the energy of radiation is the only variation, depending on the thickness of the tumor. A few schemes of equivalent chronological factors are presented, giving less than 1 p. 100 risk of recurrence and a small risk of late radiolesions for normal tissues.
