[Ruptured renal artery aneurysms in microscopic polyangiitis].

INTRODUCTION

Renal artery aneurysms are unusual manifestations of microscopic polyangiitis.

OBSERVATION: We report the case of a 55 years old male patient, with a microscopic polyangiitis, which was revealed by a demyelinating polyradiculoneuropathy, the diagnosis was made with association of alveolar hemorrhage, peripheral neuropathy and glomerulonephritis with positive antineutrophil cytoplasmic antibodies (antimyeloperoxidase antibodies). The evolution was marked by a state of shock by rupture of aneurysms of intrarenal arteries.

CONCLUSION

This case emphasizes the importance of looking for complications of unusual type of intrarenal aneurysms in patients with microscopic polyngiitis.
