Une cause exceptionnelle de chylothorax : l'amylose primitive

We report an original case of primary amyloidosis presenting as a chylothorax and confirmed by an endomyocardial biopsy. We highlight the multi factorial character of pleural effusions associated with amyloidosis. This explains the delay in treatment and the disease's critical nature (median survival 2 months). The prognostic value of proBNP is also emphasised.
