[Calcified lipogranuloma after gomenoleo oil injection: "paraffinoma" 60 years later]. / Lipogranulome calcifié après injection d'huile goménolée: un "paraffinome" 60 ans après.

The authors describe one case of calcified lipogranuloma observed in the forearm tissues of a 67 year old patient. This lesion seems to be due to a long term treatment by S.C injection of gomenoleo oil 60 years before. The analysis by high performance liquid chromatography of fat parts of the lesion identified the original olive oil (excipient).

[Temporomandibular arthrography]. / Arthrographie temporo-mandibulaire.

Results of 104 arthrotomography scans with contrast of temporomandibular joints of 71 patients are used to define normal arthrography criteria (15.4% of cases). Reducible anterior displacements represented 28.8% of cases, non-reducible displacements 40.4%, perforations 12.5% (5.8% associated with a reducible luxation, 6.7% with a non-reducible luxation). The failure rate was 2.9%. Arthrography provides important information on articular morphology and dynamics, the state and position of the meniscus and of the posterior brake, and the state of the joint capsule. Performed by an experienced operator it possesses few complications.

[Posttraumatic infarction with a surgically treated floating thrombus of the left ventricle. Apropos of a case]. / Infarctus post-traumatique avec thrombus flottant du ventricule gauche traité chirurgicalement. A propos d'un cas.

Forty-two days after severe thoracic trauma which had led to thrombosis of the left renal artery and to nephrectomy, a 22 year old patient developed anterior wall infarction. Echocardiography and coronary and left ventricular angiography showed distal occlusion of the left anterior descending artery and the presence of a large, mobile thrombus at the left ventricular apex. The thrombus was removed surgically without any complications but a small thrombus adherent to the ventricular scar was observed postoperatively. After a discussion on the different possible physiopathological mechanisms, the authors conclude that the patient probably suffered primary myocardial contusion which led to secondary occlusion of the LAD artery, late myocardial infarction and extension of the initial intraventricular thrombus. This case illustrates the value of two-dimensional echocardiography in the detection and follow-up of ventricular thrombosis.

[Echography in pneumopericardium. Value of the subxiphoid approach]. / L'échographie dans le pneumopéricarde. Intérêt de la voie sous-xyphoïdienne.

Para-sternal echocardiography proved impossible in a case of a large pneumopericardium caused by an oesophageo-pericardial fistula. However, M mode and sector scanning showed separation of the pericardium, giving non-homogeneous echoes, and shaded echographic areas caused by the interference of air which masked all recognisable structures. This occurred in time with systole, a sign which we associate with the pneumopericardium itself.

[Sonographic patterns of ascariasis and distomiasis in the biliary ducts (author's transl)]. / Aspect ultrasonore des ascaridioses et distomatoses des voies biliaries.

Concerning two cases of ascariasis and one case of distomiasis in the biliary ducts the authors describe the sonographic patterns leading to the ultrasonic diagnosis of those biliary parasites.--The "strip sign" characterizing ascaridiasis.--The "olympic ring gallbladder".

[Ultrasonic diagnosis of intraperitoneal fluid in Morrison's pouch (and in the splenoperitoneal recess): the moon crescent sign (author's transl)]. / Le diagnostic ultra-sonore des collections intrapéritonéales dans le récessus hépato-rénal (ou le récessus spléno-péritonéal): le signe du croissant de lune.

Morrison's pouch, and, accessorily, the spleno-peritoneal recess, constitute specific indicators of the presence of intraperitoneal fluid. Intraperitoneal fluid gives rise to sonolucent atraip between the reflectivity of mean intensity of the liver and spleen, and the intense reflectivity of the perirenal fat. That image, which the authors term the "moon crescent sign", is displayed even when the fluid volume is as small as 30 to 40 ml. It is encountered in presence of ascites, but also in presence of fluid of inflammatory origin, of fluid due to pancreatic autolysis, or of blood. Hence the display of a moon crescent sign is of particular interest in the radiologic evaluation of an acute abdomen.

[Metastases of the cervico-occipital junction. The value of tomographic detection of prefracture forms (author's transl)]. / Les métastases de la charnière cervico-occipitale. Intérêt de la détection tomographique des formes pré-fracturaires.

The authors stress the frequency of metastases of the cervico-occipital junction unrecognized in medical literature: 30 cases have been diagnosed within four months. They report their different patterns and complications and insist on the prefractured pattern with osteolysis of the body of C-2 which can be shown only by polytomography. The authors propose that a tomographic study of the cervico-occipital junction should be systematically included in every analysis of metastatic extension of osteophilic tumors.
