Abstract

LOZANO ESPINOSA, Diego Alejandro et al. PURULENT PERICARDITIS AS A COMPLICATION OF PNEUMONIA IN AN INFANT. CLINICAL CASE REPORT. Case reports [online]. 2018, vol.4, n.1, pp.30-38. ISSN 2462-8522.  https://doi.org/10.15446/cr.v4n1.65333.

Introduction:

Purulent pericarditis is an inflammatory process in the pericardium caused by bacterial infection. If experienced during childhood and with untimely diagnosis, it has a high mortality rate.

Case presentation:

A 10-month-old infant was admitted to a high complexity pediatric hospital in the city of Bogotá D.C, Colombia, due to clinical symptoms including cough, respiratory distress and fever. A chest x-ray was taken showing cardiomegaly and multilobar pulmonary involvement. The echocardiogram showed global pericardial effusion managed with pericardiotomy, in which 50 mL of turbid fluid with whitish membranes was obtained. Cytochemical test revealed 2 600 mm3 leukocytes with 90% PMN and protein elevation. Purulent pericarditis was diagnosed based on imaging and laboratory findings. Treatment was initiated with ceftriaxone and clindamycin for four weeks, obtaining effective clinical and echocardiographic resolution.

Discussion:

The clinical presentation and imaging, paraclinical and electrocardiographic findings suggested purulent pericarditis as the first possibility. This diagnosis was confirmed considering the characteristics of the pericardial fluid, which was compatible with an exudate. Clinical resolution supported by antibiotic management corroborated the diagnosis, even though microbiological isolation was not obtained in cultures.

Conclusion:

Purulent pericarditis is a rare disease in pediatrics and has a high mortality rate. Making a timely diagnosis and administering early treatment are related to a better prognosis of this pathology.
