Acute bacterial endocarditis and renal microaneurysms.

aneurysms (Figure 1a). There were no signs nor sympIntroduction toms of polyarteritis nodosa nor microscopic polyarteritis. The arterio-venous fistula was successfully treated Renal aneurysms are common in polyarteritis nodosa, by embolization. The patient received antibiotics for either idiopathic or associated with HBV or HCV 10 weeks (teicoplanin, ofloxacin and meticillin). Due infection [1]. They have been rarely reported in fibroto gross haematuria and radiocontrast media injection, muscular hyperplasia, systemic lupus erythematosus, renal function initially worsened and the patient was Wegener granulomatosis, and Henoch-Schönlein purtreated by haemodialysis for 2 weeks; subsequently, pura. During infective endocarditis, mycotic aneurysms renal fuction gradually improved and serum creatinine may involve renal arteries but, to the best of our reached 120 mmol/l and proteinuria 0.6 g/l at discharge knowledge, the occurrence of bilateral, diffuse intrapar(2 months). A second angiography, performed 6 enchymatous renal artery aneurysms has not been months later, showed the total disappearance of renal reported. aneurysms; in addition, there were no aneurysms in the coeliac or mesenteric arteries (Figure 1b and c).
