[Complications of adrenal angiography (author's transl)].

Since new ways of radiodiagnostic exploration of the adrenal glands are now performed, it is important to take stock upon the complications of adrenal angiography. These complications are very different according to the fact that we explore pheochromocytomas or not. The complications of stimulation, of hypertensive accident or collapsus are quite specially observed during the angiography of pheochromocytomas. They must be prevented by a selection of the indications and a reanimation pre and per angiography. Lesions of glandular destruction that lead to a hormonal insufficiency (sometimes therapeutic) are observed outwards pheochromocytomas. Because they depend upon the explored adrenal lesion and specially of the angiographic conditions of the exploration, these complications must be prevented by a rigorous technic.

[Cauda equina syndrome disclosing adenocarcinoma of the ethmoid].

Cauda equina metastases have been exceptionally described in sinusal neoplasms. MRI with gadolinium injection show up the primitive lesion and its neurologic extension. We report a case of cauda equina syndrome in which, only MRI, had show up intradural metastases and localised the ethmoïd sinus carcinoma.

Sensitivity of magnetic resonance imaging of the wrist in very early rheumatoid arthritis.

The aim of this study was to evaluate magnetic resonance images (MRI) of soft tissue abnormalities in the wrist of RA patients in the early stage of the disease. We performed magnetic resonance imaging of the wrist in 15 patients with early rheumatoid arthritis according to ACR criteria, of less than 10 months duration (mean duration 4.8 months). None of the patients had carpal bone erosions on standard radiography. MRI demonstrated abnormality of the soft tissue in 13 of the 15 cases. On coronal MRI, the sites of involvement of the synovitis were the recess of the distal ulnar (9 pts.), the distal radioulnar joint (4 pts.) and the radiocarpal joint (7 pts.). On axial MRI, tendon sheath effusion of the digital flexor was present in 3 patients. Carpal bone lacunae were present in only 4 patients. Disease activity was not associated with the extent of the synovitis on wrist MRI. Our study suggests that MRI is a sensitive method for the detection of synovitis in early RA.

[Arterial radio-anatomy of the extrahepatic biliary system (author's transl)].

The uni-arterial vascularisation of the lateral bilary duct makes it impossible to systematise the arteries which supply the common bile duct. Only the cystic artery is seen at coelio-mesenteric catheterization. The techniques essential for visualisation of the cystic artery are discussed, on the basis of one hundred coelio-mesenteric arteriograms: frequency of demonstration, origin, course, termination, calibre and length. The frequent finding of opacification of the wall of the gall bladder under normal conditions is stressed.
