[Ultrasonic aspects of abdominal abscesses and hematomas].

Abdominal ultrasonography often enables to display the fluid collection of an abcess or haematoma. This type of diagnostic procedure is most useful in a post-operative period. The intestinal gases which stop the ultrasonic beam may be responsible for diagnostic failures. Positive results, which are the most frequent, are never the less precious to assess and decide a treatment policy.

Ultrasonic study of venous patterns in the right hypochondrium: an anatomical approach to differential diagnosis of obstructive jaundice.

Through real time ultrasonography, it is possible to display the splenic vein, the superior mesenteric vein, the vena porta, and the intrahepatic portal and systemic veins. In jaundice, it is of the utmost importance to carefully identify the vena porta before making a diagnosis of common bile duct enlargement. It is also necessary, when confronted with a pattern of apparently enlarged intrahepatic ducts, to conduct a thorough study of possible confluences of the ducts with the vena porta or vena cava to be certain that the ducts are not part of the portal or systemic venous network. Without such differentiation, portal enlargement caused by portal hypertension, systemic venous enlargement caused by cardiac insufficiency, or even nonpathological wide veins may lead to an erroneous diagnosis of obstructive jaundice.

[Ultrasonic diagnosis of pancreatic conditions: a new tentative at a rational approach based on the analysis of 300 cases which were checked (with real time and degraded intensity scale). (author's transl)].

For a long time, echotomography of the pancreas was limited to the identification of pseudocysts. Little by little, those using ultrasound learnt how to construct images of the pancreatic gland itself, and faced with the changes in size and shape of the latter to recognize lesional processes. Analysis of the pancreatic echostructure represents an important step in the progress of the diagnosis of lesions. Echotomography, the results of which must be compared with those of roentgenological methods of exploration, as well as the clinical and laboratory data, enables the attainment of very fiable diagnoses of chronic pancreatitis with or without pseudo-cysts, of acute pancreatitis or of rare cystic tumors. The precision of the results however depends fundamentally on technical data: it is necessary to combine with the classical apparatus, with manual displacement of the wave, a tomo-echoscopic apparatus, with real time; above all, it is necessary to use the degraded intensity scale. This scale is innate in real time apparatuses. At present it takes the form of a complementary module, on the classical apparatuses. Without these technical conditions, real time and degraded intensity scale, it seems impossible to attack the problem of ultrasonic diagnosis of pancreatic conditions, except by exposing oneself to disappointments which would unmeritedly cast discredit on the method. Six years of experience, several thousands of pancreatic examinations, three hundred pancreatic lesions which were anatomically checked has however convinced us of the importance of echotomography in this field.

[Post-traumatic L5-S1 root avulsion. Myelographic and x-ray computed tomographic study. Apropos of a case. Review of the literature].

A patient presented an avulsion of left L5-S1 roots, with S1 meningocele, following a road accident. Saccoradiculography and CT scan imaging, even without contrast, allowed identification of total lesion in a suggestive clinical context. The characters of the CT scan images are emphasized. Images showed also the presence of pseudo-meningoceles and absence of roots.

[Ultrasonic patterns of giant hypertrophy of the gastric mucosa (Ménétrier's disease) (author's transl)].

Since it can display the gastric folds, as well as the gastric wall and the exogastric area, sonography is a reliable way of diagnosing the giant hypertrophy of the gastric mucosa (Ménétrier's disease). The characteristic pastterns are: --a considerable thickening of the gastric folds and wall, --a high sonolucency, --the presence of the intra-mural cysts, --some "hilly" deformations in the exogastric part of the stomach, --occasionally, a mesenteric lipomatosis.
