A 36-year-old man with underlying diabetes mellitus presented with a 2-week history of left-sided neck pain, fever, and dysphagia. Physical examination revealed a left intraoral lesion discharging pus. Incision and drainage of the lesion were performed, yielding approximately 10 cm^3^ of purulent material. A contrast-enhanced computed tomography (CT) scan of the neck revealed bilateral retropharyngeal collections (Figure 1). CT thorax and abdomen revealed no abnormalities. Pus culture grew Burkholderia pseudomallei, which was susceptible to ceftazidime, meropenem, and trimethoprim-sulfamethoxazole. Blood cultures were negative. The patient was treated with intravenous ceftazidime 2 g every 6 hours for 2 weeks, followed by oral trimethoprim-sulfamethoxazole for eradication therapy upon discharge.

Deep neck space infections are serious because of airway and vital structure involvement. Although usually polymicrobial, B. pseudomallei is a rare cause. Melioidosis is a tropical disease caused by *B. pseudomallei * ^(1)^. Retropharyngeal abscess caused by melioidosis is exceptionally rare. In addition to appropriate antimicrobial therapy, appropriate imaging and surgical drainage of the abscess is an important part of management ^(2)^.
