2019 Novel Coronavirus (COVID-19) Pneumonia withHemoptysis as the Initial Symptom: CT and ClinicalFeatures

ABSTRACT

Recently, some global cases of 2019 novel coronavirus (COVID-19) pneumonia have been caused by second- or third-generationtransmission of the viral infection, resulting in no traceable epidemiological history. Owing to the complications of COVID-19pneumonia, the first symptom and imaging features of patients can be very atypical and early diagnosis of COVID-19 infectionsremains a challenge. It would aid radiologists and clinicians to be aware of the early atypical symptom and imaging featuresof the disease and contribute to the prevention of infected patients being missed.
