CLINICAL IMAGE
A 35-year-old man with fever, cough, and worsening short of breath was
hospitalized with COVID-19 pneumonia. His chest computed tomography (CT)
showed bilateral patchy consolidation and ground-glass opacities (GGO)
(Figure 1A). He received oxygen and ciclesonide inhalation. Mechanical
ventilation was not required. Twenty-six days after, CT on discharge
showed a cystic feature in the left mediastinal side (Figure 1B). As he
was physically recovered and the blood test did not show any
inflammatory findings, only CT follow-up was conducted. Further four
weeks later, a new cystic feature enclosed by thickened wall were found
in the epiphrenic side (Figure 1C). Again he was asymptomatic with no
abnormality in the blood test. Further four weeks later, both cysts had
spontaneously disappeared without intervention (Figure 1D).
COVID-19 pneumonia is a viral infection which is reported to present
with GGO, patchy shadowing, and interstitial
abnormalities.1 Cystic features and pleural
involvement are less reported except for mechanical ventilation
.1,2 Its etiology is still poorly understood, but it
may be caused by parenchymal ischemic damage and
fibrosis.2 We want to emphasize that physicians should
pay attention to follow up the late phase of COVID-19 pneumonia for
better understanding its clinical course in the convalescing period.
