LASSO DIAZ, Edgardo  and  FLORES RUEDA, Ariel. Myocardial abscess secondary to community acquired Pseudomona aeruginosa pneumonia in an immunocompetent infant: case report. Med. leg. Costa Rica [online]. 2023, vol.40, n.1, pp.17-22. ISSN 2215-5287.

Pseudomona aeruginosa is an important cause of health care-associated infections and in community-acquired pneumonias, it is rarely identified as the pathogenic agent, being of rapid progression and poor prognosis.

This is a one-year-old immunocompetent minor who died at home one week after a lesion in the sole of the right foot which, according to family members, caused "pus", treated with anti-inflammatory and analgesic drugs. A necropsy was performed, which showed a scar on the sole of the right foot with no traumatic lesions. Lungs of indurated consistency, with adhesions and areas that appear necrotic, associated with pleural effusion. The histological study reported an abscessed acute pulmonary infectious process that spread by continuity to cardiac tissue and microbiological studies of lung and spleen reported Pseudomona aeruginosa.

Keywords : Pseudomonas; pneumonia; immunocompetent; myocardial abscess.
