The May-Thurner syndrome is a well-known anatomical anomaly where the left common iliac vein (LCIV) is compressed between the right common iliac artery and the fifth vertebral body. This report describes the case of a "right-sided" May-Thurner syndrome where the right common iliac vein (RCIV) is compressed by the left common iliac artery in a patient with a(More)
PURPOSE To evaluate the role of contrast enhanced US in the characterization of renal tumors. Materials and methods. Eighty-six renal tumors (33 solid, 53 cystic) underwent contrast enhanced US after indeterminate CT/MRI (67 lesions) or US (19 lesions). Pathological correlation was available for 42 cases, and follow-up at 3 and 6 months was available for 13(More)
Three types of involvement of the rectum and recto-sigmoid by carcinoma of the prostate are reviewed through an analysis of eight cases. A fourth type with subserosal metastatic implant of the proximal sigmoid may occasionally be encountered. The roentgenographic findings are not pathognomonic, but are characteristic of extrinsic involvement of the bowel(More)
Left ventriculography is of great interest in the diagnosis and prognosis of congenitalaortic stenosis. It permits one to distinguish valvular stenosis, which is the commonest type, from sub-valvular stenosis, of which there exist 5 main type; type I and II are the commonest, they have a better prognosis than types III and IV. Sub-sigmoid aortography shows(More)
The authors report a case of ataxic hemiparesis (dysarthria-clumsy hand syndrome plus crural hemiparesis with homolateral ataxia), secondary to a single cerebellar lacuna (CT scan), in a left rostral para-vermian position in the vicinity of the peduncle and secondary to arterial hypertension. They discuss the nosological aspects of this recently established(More)
The 3D balanced gradient-echo technique is described along with th eimaging protocol for MR imaging of th ecoronary arteries. A 3D volume with spatial resolution of 0.6 x 0.6 x 0.75 mm composed of 140 slices covering the whole heart is acquired over 10 minutes. The main advantage of this whole heart technique is the possibility to image the coronary(More)
Twenty-three patients with congenital subvalvular aortic stenosis are reviewed. The importance of classifying this stenosis into four types based on angiocardiographic findings is stressed, as are the indications for left heart catheterization during the preoperative and postoperative course of the disease. The type of congenital subvalvular aortic stenosis(More)
In a psychiatric service, this study compares results for the psycho-organic syndrome diagnosed with the Rorschach test to results from brain CT Scan in two groups (20 patients with cerebral atrophy and 20 patients with normal CT Scan). Our results are consistant with previous results mainly for patients with cerebral atrophy as demonstrated by(More)
