[Selective arteriography of the supra-aortic trunks by right humeral approach with a 4F catheter].

Three hundred and sixty seven patients were studied for cerebrovascular disease with intra-arterial digital subtraction. Examination were performed using a right transbrachial approach with a 4F catheter. Selective catheterization of the carotid arteries was possible in 98% for the left and 99% for the right. Image quality was consistently good or excellent. There was 2 neurologic complications and 1 local complication (hematoma) requiring surgery few weeks later. Selective carotid and vertebral catheterizations by the brachial route is safe, simple, accurate and rapid (15 mn) and can be employed in outpatients.

Computed tomography (CT) and magnetic resonance imaging (MRI) of pleural masses.

Depending on the location, size, and underlying histologic features, pleural masses may produce a large spectrum of findings. While a number of imaging modalities may be used, plain chest radiographs remain the most common examination in the initial assessment of these patients. In this article, we review the use of two noninvasive techniques: computed tomography and magnetic resonance imaging. For the purpose of this review, localized pleural masses and diffuse pleural masses are discussed separately. Among the various pleural masses, metastatic disease represents the most frequent neoplasm.

[Intra-arterial fibrinolysis of superior mesenteric artery embolism].

Intra arterial fibrinolysis for acute mesenteric embolism. Acute mesenteric ischemia has a poor prognosis because the diagnosis is often too late (greater than 12 h), leading to a difficult surgery in old patients. The lesions of the bowel don't always allow a single operative embolectomy but often need a resection when there is a long time interval between onset of symptoms and therapy. We report a case of acute embolism in the superior mesenteric artery with the clot located in its terminal part. A rapid diagnosis was made by arteriography and intra-arterial fibrinolysis was attempted with success permitting the complete cure of the affection, without sequellae. This treatment is only likely to be successful if it is carried out within 10-12 hours of the onset of clinical signs and symptoms.

Intrapancreatic lipoma. First case in the literature.

A round mass was found by an abdominal ultrasonography in the head of the pancreas of a 63 year-old woman. Ultrasonography was performed because of abdominal pain. Percutaneous aspiration cytology suggested pancreatic adenocarcinoma. A pancreatoduodenectomy was performed heading to the discovery of an intrapancreatic lipoma. This lesion should be added to the list of benign connective tissue tumors of the pancreas.

Cyst formation in gastric heterotopic pancreas: report of two cases.

Cyst formation is an uncommon pathologic finding in heterotopic pancreas. It is sometimes reported in a duodenal location but very rarely in a gastric location and leads to very large lesions of unusual endoscopic and radiographic appearance. Two cases of gastric heterotopic pancreas are described in which cystic zones in the gastric wall were found at preoperative ultrasound or computed tomography.

Spinal involvement in alveolar echinococcosis: assessment of two cases.

Two cases of spinal involvement in alveolar echinococcosis are reported. Conventional radiographs showed bone lysis and spondylitis; computed tomographic scans showed detail of local spread to the ribs, other vertebrae, and soft tissues. Differential diagnosis, which includes other infections and hydatidosis, is difficult, and the diagnosis may be suggested by evidence of a primary hepatic focus, geographic propensity to the infection, and laboratory findings.

[Pseudolinitis plastica of breast origin].

The most common type of gastric metastases secondary to carcinoma of the breast is the one showing a linitis plastica appearance. The roentgenologic aspect when performing an upper gastrointestinal examination with barium contrast is typical and allows the differential diagnosis with the primitive linitis. The linitis plastica type of metastatic breast carcinoma results from transmural infiltration of the stomach wall with initial deposit of tumor cells in the submucosal or subserosal regions. CT provide valuable information concerning the metastatic spread.

[Tuberculous trochanteritis: value of ultrasonic diagnosis and x-ray computed tomography. Apropos of 3 cases].

Trochanteritis is a rare osteoarticular site of tuberculosis which initiates within the serous bursa of the gluteus maximus and extends only secondarily to the greater trochanter. Its course is a slow one. Diagnosis is usually delayed but should be made earlier by the use of ultrasound and the CT scan. These provide details of the bone remodelling detected on standard radiography, and show the presence of a variable fluid collection of a topography that attaches it to the serous bursa of gluteus maximus, and provides a guide to diagnostic needle puncture for biopsy. Overall data allow improved adaptation of medico-surgical treatment.

[Prognosis and surgical indications in acute pancreatitis. Contribution of abdominal x-ray computed tomography].

The authors have retrospectively studied 17 patients with acute pancreatitis to see if computed tomography (CT) findings were correlated with the clinical type of acute pancreatitis. This study permit to say that a normal CT scan is possible with an edematous pancreatitis. There is no necrotizing pancreatitis with normal CT scan. But, in 11 CT scan with severe appearance, 6 patients had an edematous pancreatitis of good prognosis. Several explanations are given, but the important thing is the lack of correlation that make CT scan of a bad prognosis value. Any way, CT scan is still the best examination for diagnosis of acute pancreatitis.

[Role of echography in the diagnosis and monitoring of hepatic alveolar echinococcosis].

By means of a review of a series of 30 cases of hepatic alveolar echinococcosis, the authors propose a classification of the various sonographic patterns; they point out the heterogeneous form which associate necrosis and calcification inside an hyperechoic mass and is the most frequent. The interest of ultrasonography for detection of lesions, its limits for diagnosis of extension, the contribution of percutaneous biopsy are discussed, as its place in the survey of the affection.

[Radiology in the diagnosis of complicated forms of annular pancreas in adults].

Radiologic findings are described in 4 cases of annular pancreas in adults. The value of double contrast exploration of the duodenum is emphasized, this showing the characteristic image of "curtain-loop" stenosis of the right D2 border with associated marked dilatation of the suprastenotic duodenal zone. Ultrasound imaging shows features suggestive of the liquid distended genu superius. The onset of acute pancreatitis on an annular pancreas leads to images of pseudo-cystic necrosis and/or calcifications suggestive of the diagnosis because of their localization on ultrasound or C.T. examination.

[Evaluation of the role of angiography in the diagnosis and surveillance of hepatic alveolar echinococcosis].

The authors recall the main pathologic and physiopathologic data necessary to understand the angiographic patterns of hepatic alveolar echinococcosis, by means of a rereading of a personal series of 37 cases. They show that this affection has a diagnostic angiographic shape which associate four signs: avascular aspect of the lesions, regular invasion of vessels, presence of a collateral circulation, absence of neovascularisation. Digestive angiography stays a good diagnostic method for the parasitosis, when epidemiological context, ultrasound or CT scan gave no explicit conclusion. It keeps an interest in the preoperative evaluation and in the supervision of portal vein.

[X-ray computed tomography in the study of anterior instability of the shoulder. Study of a series of 23 cases].

The place of standard CT scan imaging more particularly when combined with double contrast arthrography, is defined in the preoperative screening of patients with anterior instability of the shoulder. The joint scan provides complete data on the anatomic elements of the shoulder lesion, particularly with reference to the glenoidal labrum and the anterior capsular structure. It is also of major diagnostic value in painful subluxations.
