We would like to share ideas on “Utility of positron emission tomography–computed tomography in the evaluation of fever of unknown origin in a resource-limited tropical nation.”[1] Das et al concluded, “Although it is a useful tool in FUO workup, especially in the diagnosis of tropical … investigations.”[1] We agree that positron emission tomography–computed tomography might be a useful tool. Using in resource-limited tropical setting is still controversial. In our setting, in tropical Asia, the tool is not easily available and the cost of investigation is high; hence, it is not generally used and is questionable for cost and utility. The tool might help identify a possible case of some infection, such as tuberculosis, but there is no definitive diagnosis from imaging investigation. The tool might provide a partial clue when there is no other clue for diagnosis of fever of unknown region[2] but most of tropical diseases usually have specific clinical characteristics in tropical medicine. A specialist in tropical medicine might have a comparative skill for clinical diagnosis of diseases when there is no imagine tool available. The treatment is mainly based on clinical presentation regardless of definitive diagnosis or advanced clinical imaging investigation.
