[Spontaneous remission of renal artery stenosis in Takayasu's disease].

The authors report about one rare case of spontaneous subsidence of tight stenosis of the left renal artery in Takayashu's disease, which was followed up on two angiograms taken with an 11-year time interval. Knowing such evolution patterns may influence the treatment of such stenoses.

[Diagnosis of disorders affecting the solid organs of the supra-mesocolic compartment].

Sonographic and computed tomographic (CT) examinations have modified the investigation of hepatic, splenic and pancreatic tumors. Because of advances in non-invasive diagnostic procedures, these different benign or malignant tumors are now more frequently detected and surgically treated. However, for these different lesions sonography is the gold standard imaging technique.

[X-ray computed tomography in pheochromocytoma. Apropos of 20 cases].

Study of 20 pheochromocytomas in 19 patients confirmed the remarkable sensitivity of computed tomography (100%) for the detection of their adrenal and juxtarenal localizations. However, ultrasonography was as effective as the CT scan in these same patients, and even detected latent tumors in several cases. Certain pheochromocytomas in this series presented unusual appearances, particularly two large tumors which were manifest as abdominal masses and a malignant form which provoked a total infarct of the homolateral kidney.
