[Compression of the right pulmonary artery by a dissecting aneurysm of the ascending aorta. Value of x-ray computed tomography]. / Compression de l'artère pulmonaire droite par un anévrysme disséquant de l'aorte ascendante. Intérêt de la tomodensitométrie.

Right pulmonary artery compression by a dissecting aortic aneurysm-value of computed tomography. The authors relate a case of dissecting aortic aneurysm occurring as a late complication of aortic valve replacement and causing right pulmonary artery compression. Computed tomography appears to be performing technique for the exploration of this unusual case.

[Compression of the right pulmonary artery by a dissecting aneurysm of the ascending aorta. Apropos of a case occurring long after aortic valve replacement]. / Compression de l'artère pulmonaire droite par un anévrysme disséquant de l'aorte ascendante. A propos d'un cas survenu à distance d'un remplacement valvulaire aortique.

The authors report the case of a dissecting aneurysm of the ascending aorta compressing the right pulmonary artery in a 62 year old man, 6 years after aortic valve replacement. The clinical presentation was that of pulmonary embolism. The diagnosis was confirmed by angiopneumography and CT scanning. The ascending aorta was successfully replaced with a Dacron prosthesis. One other case was found in a review of the literature. After discussing the predisposing factors of aortic dissection during cardiac surgery, the authors underline the diagnostic value of CT scanning in cases of suspected aneurysms of the thoracic aorta.

[Striated and delayed nephrography]. / Néphrographie striée et prolongée.

About a case of striated and delayed nephrogram seen on a diabetic child, authors come back to the different etiologies. Among them, the tubular precipitation of Tamm-Horsfall protein seems to be given like on the right possibilities. Whatever is its etiology, the mechanism of striated appearance is always the same, being founded on the radiated disposal of the collecting ducts and on a tubular stasis beeing with iodine concentration.

[Semiology of pseudotumoral forms of hydatid cyst of the liver. Apropos of 7 cases]. / Séméiologie des formes pseudo-tumorales de kyste hydatique du foie. A propos de sept cas.

Seven hydatid cysts of the liver were detected by ultrasound and confirmed surgically. On ultrasound scans they were mimicked tumors (Type IV according to the classification established by W. Hassine) and there was a high level of echoes. Two masses were surrounded by a spiral completely free of echoes. Five masses were limited by a border completely free of echoes.
