Septic pulmonary embolism (SPE) is an uncommon, but life-threatening event that is usually associated with extrapulmonary infections. We report the first case of bilateral SPE secondary to a central venous catheter-related bloodstream infection involving pathogens commonly considered environmental contaminants: Tsukamurella tyrosinosolvens and Rhizobium radiobacter. Empirical levofloxacin treatment was confirmed by in vitro susceptibility data and produced prompt clinical improvement, but removal of the infected line proved indispensable for eradication of the infection. Laboratory personnel should be aware of the pathogenic potential of these environmental organisms, particularly in immunocompromised hosts with indwelling catheters.
