ABSTRACT
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although the reference standard for SARS-CoV-2 diagnosis is real-time reverse transcription polymerase chain reaction (RT-PCR), computed tomography (CT) is recommended for both initial evaluation and follow-up. There is a growing body of published evidence about CT evolution during the course of COVID-19 pneumonia. Here, we report six confirmed cases of COVID-19 patients who underwent unenhanced chest CT on admission and after 4 months from the onset of symptoms. Chest-CT at first admission showed the typical CT features of COVID-19. Interestingly, the follow-up CT revealed the persistence of lung abnormalities in five cases even if all the patients were completely asymptomatic. Further studies are needed for a comprehensive understanding of the disease progression and the resulting late imaging modifications.
ABSTRACT
Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). First identified in December 2019 in Wuhan, China, it has since become a global pandemic. Although the reference standard for SARS-CoV-2 diagnosis is real-time reverse transcription polymerase chain reaction (RT-PCR), computed tomography (CT) is recommended for both initial evaluation and follow-up. The CT findings in COVID-19 are varied, but typical ground-glass opacities are usually reported to occupy a peripheral costal subpleural distribution. Here we report eight confirmed COVID-19 cases who underwent clinical evaluation, laboratory testing, and unenhanced chest CT. In all patients, chest CT showed the presence of ground-glass opacities in the mediastinal subpleural parenchyma. While these cases also showed the typical CT features of COVID-19, involvement of the mediastinal subpleural parenchyma should not lower the index of suspicion for COVID-19.

Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). First identified in December 2019, in Wuhan, China, it has since become a global pandemic. Complications of COVID-19 are not limited to the pulmonary system, but also include neurologic manifestations such as stroke. We report two cases of coincidental presentation of COVID-19 and cerebrovascular accident. Further studies are needed for a comprehensive understanding of the neurological pathology of COVID-19 and its effects on the nervous system, but stroke teams should be wary of the fact that COVID-19 patients may present with cerebrovascular accidents.
