A rare case of melioidosis presenting as pericarditis and pneumonia in a patient with poorly controlled diabetes mellitus

Abstract

Melioidosis is a rare but often fatal tropical infection caused by gram-negative bacteria Burkholderia pseudomallei. It most commonly manifests as pneumonia and rarely presents as pericarditis. Melioidosis can be difficult to diagnose because of its diverse clinical manifestation and close resemblance to bacteria of the genus Pseudomonas. We report a rare case of melioidosis presenting as pericarditis and pneumonia in a 61-year-old male patient with poorly controlled diabetes mellitus. He was initially misdiagnosed with Pseudomonas aeruginosa infection and later treated empirically as tuberculosis pericarditis for 2 months, before reaching the diagnosis of melioidosis.
