We report a case of Rhodococcus equi, an unusual pathogen, causing a r
ight upper lobe lung abscess in a patient with Evan's syndrome (auto-i
mmune haemolytic anaemia and thrombocytopenia) who was treated with hi
gh-dose corticosteroid therapy. The patient was treated successfully w
ith clarithromycin, vancomycin, ciprofloxacin and imipenen which appea
r to be effective in combination for this unusual condition in which t
he treatment regimen has been controversial.
