Papillary necrosis: a late complication of nephropathia epidemica?

In the following we describe a case of nephropathia epidemica, which exhibited, a few years after acute infection, arterial hypertension and multiple papillary necrosis. Papillary necrosis was diagnosed by i.v. pyelography and CT Scan. A complete evaluation of the patient failed to show any other etiology for medullary necrosis. If arterial hypertension has already been reported as a complication of nephropathia epidemica, papillary necrosis is exceptional, but may be explained by the severe vascular troubles engendered by Hantavirus infection in kidney medulla.
