Other diagnostic tests

Echocardiogram

• It is done to rule out lung abscess suspected secondary to septic embolism from right-sided (e.g., tricuspid valve) bacterial endocarditis.
• It reveals vegetations on the affected valve.

Rapid ELISA for D-dimer and V/Q scan

• It is done in patients when lung abscess is secondary to infection of an infarct-related pulmonary embolus.
• D-dimer is elevated in pulmonary embolism, care must be taken to consider other conditions associated with elevated d dimer.
• V/Q mismatch is seen in seen in patients with PE
