Radiological findings and their clinical correlations in nephropathia epidemica.

Nephropathia epidemica (NE) is a mild form of hemorrhagic fever with renal syndrome (HFRS). Its course varies from asymptomatic to fatal. The etiologic agent, Puumala virus, belongs to the Hantavirus genus of the Bunyaviridae family. Respiratory symptoms, from common cold to respiratory distress, occur in NE. Acute renal failure (ARF) is evident in over 90% of hospital-treated NE patients. In this review article, special attention is paid to radiological lung and renal involvement to investigate the occurrence and type of manifestations during the acute phase of infection and recovery.
