ABSTRACT

Chest CT imaging can be helpful in early diagnosis of COVID-19 instead of relying on real time polymerase chain reaction (RT-PCR) that can give false negative result. Nasopharyngeal samples from a 22 years old man were detected as negative for COVID-19 for consecutive three RT-PCR tests. Complete blood count (CBC), D-dimer, serum ferritin, eosinophil sedimentation rate (ESR) test, tuberculosis test, real time PCR and high-resolution computed tomography (HRCT) were done to rule out the cause of flu like symptoms. HRCT reveals a haze area in the right perihilar region adjacent to medial part of horizontal fissure on the 3rd day of manifestation of symptoms. Radiological studies showed early consolidation of COVID-19 whereas RT-PCR showed negative results. Chest CT imaging is a highly sensitive technique that has also been used in detection of corona virus. This case study emphasizes the importance of HRCT for early and confirm diagnosis of COVID-19 whereas RT-PCR results can vary. This process may show negative results and is time consuming.
