Abstract

In 1936, Löeffler first recognized the association between a distinctive form of severe heart failure and marked eosinophilia. Most cases are caused by either parasitic infections or drugs; however, no cause has been identified in one-third of the patients [1]. This report presents a rare case of Löeffler's syndrome caused by the parasite Paragonimus westermani.

Keywords: Eosinophilia; Heart failure; Löeffler's syndrome; Paragonimus westermani.
