LEPTOSPIROSIS PRESENTING AS FEVER AND ISO LATED INTRAALVEOLAR HEMORRHAGE

We report observation of a patient of 25 years who presented with an i solated intra-alveolar haemorrhage occuring during the course of an il lness suggestive of speticaemia. Considering the epidemiological conte xt of inhalation of water from the River Saone, the diagnosis of acute leptospirosis ictero-haemorrhagica was considered and was comfirmed b y serological tests. Several publications draw attention to the pulmon ary manifestations of acute leptospirosis which remains rare and poorl y understood. Pulmonary disease is characterised not by an infectious alveolitis but by the occurence of intra-alveolar haemorrhage whose pa thogenetic mechanism remains under discussion.
