Disseminated Melioidosis Complicated by Right-Sided Infective Endocarditis: A Rare Case of Pulmonary Valve Involvement.

ABSTRACT:

Background

Melioidosis caused by gram-negative bacilli, Burkholderia pseudomallei, can present with a wide range of illnesses, from pneumonia and cutaneous infection to disseminated disease with severe septicemia.

Case summary

A 55-year-old man with newly diagnosed diabetes presented with fever and productive cough. Chest radiograph showed right-sided lobar pneumonia. Blood cultures, endotracheal tube culture and sensitivity testing, and bronchoalveolar lavage confirmed a diagnosis of disseminated melioidosis. Transesophageal echocardiography showed a large, 4.8 × 1.28 cm mass at the pulmonary valve, another mass at the tricuspid valve, and inferior vena cava thrombus. Left ventricular ejection fraction was significantly reduced (21%). These findings were suggestive of right
