[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.

[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.

Alveolar echinococcosis of the liver: MR findings.

Nineteen cases of proven hepatic alveolar echinococcosis were examined by magnetic resonance (MR) and the results were compared with CT. Fibrous and parasitic tissue showed low signal both on T1- and, generally, on T2-weighted images. In a few cases a high signal on T2-weighted images may be observed, due either to central necrotic zones or to small peripheral cysts.

[Chordomas of the cervical spine. Typical radiological aspects. Apropos of 2 cases].

Two cases of cervical chordomas are reported. Diagnosis is based on plain film and CT, and confirmed by transcutaneous biopsy. Therefore CT was helpful in evaluation of local recurrence and spinal metastasis.

[Demonstration of the arterial system during phlebography of the leg for blue phlebitis].

Massive filling of thigh and calf arterial network was noted during phlebography in a patient with a typical clinical picture of "blue" phlebitis of lower limb. This paradoxical vascular injection allows support of current physiopathologic concepts of "blue" phlebitis (phlegmasia cerulea dolens).

[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 findings of laryngeal involvement in von Recklinghausen disease.

In two patients with laryngeal von Recklinghausen disease, CT demonstrated hypodense, well-defined, septated masses sparing the epiglottis, and with little enhancement after contrast medium injection. Additional cervical lesions, benign or occasionally malignant, may also be seen.
