Systemic Melioidosis with Acute Osteomyelitis and Septic Arthritis Misdiagnosed as Tuberculosis: A Case Report.

Melioidosis, also called Whitmore's disease, is an infectious disease caused by the bacterium Burkholderia pseudomallei. It is predominantly a disease of tropical climates, especially in Southeast Asia and northern Australia. Due to a wide range of signs and symptoms that can be mistaken for other diseases such as tuberculosis or common forms of pneumonia, patients can be frequently misdiagnosed, which can have adverse consequences and can make management more complicated. This case report elaborates on the clinical course of a middle-aged nondiabetic male patient who presented to our hospital with fever for two months and painful swelling of the right proximal leg for 10 days, following a previous diagnosis of disseminated abdominal tuberculosis made at a different healthcare center. Preliminary investigations confirmed multiple diagnoses of acute osteomyelitis and septic arthritis complicated by multiple hepatic and splenic abscesses. Given the patient was in a state of septic shock at the time of presentation, he was managed as an emergency case and an arthrotomy of the knee joint was performed followed by decompression and drainage of the right proximal tibia. As per standard hospital protocol, the pus and synovial fluid were sent for microbial culture and sensitivity, at which point B. pseudomallei was isolated and the diagnosis was confirmed. Diagnosis of melioidosis requires a high degree of suspicion among clinicians and microbiologists, especially in individuals that have frequent exposure to contaminated soil and water and have a travel history to endemic countries.
