Streptococcus milleri infection of a hepatopulmonary hydatid cyst

A case of hepatopulmonary hydatid disease in a Cypriot who presented with pyogenic infection with Streptococcus milleri is described. Although hydatid disease and pyogenic liver abscess are both rare in the UK, an underlying echinococcal pathology should be suspected in any patient from an area endemic for hydatid who presents with a pyogenic hepatic or hepatopulmonary abscess.
