Pneumonia in the Pandemic: Not Always COVID-19

The coronavirus disease 2019 (COVID-19) pandemic has changed the way we manage patients, especially those with respiratory illnesses. Clinical manifestations, chest imaging, and reverse-transcription polymerase chain reaction (RT-PCR) play major roles in diagnosing respiratory infections during a pandemic. However, several infections can mimic COVID-19 regarding its clinical signs, symptoms, and imaging appearance. Diagnosing pneumonia other than COVID-19 is a big challenge in developing countries, given the limited resources available. We presented a case of a 25-year-old female with clinical symptoms and radiological characteristics typical of COVID-19 but a repeated negative RT-PCR test. Further workups found lung tuberculosis as her primary diagnosis. Our patient continued treatment with an antituberculosis agent and a short course of steroids, with a remission of symptoms.
