Follow-up computed tomography scan in post-COVID-19 pneumonia.

The coronavirus disease 2019 (COVID-19) global pandemic can be a severe illness that leads to morbidity and mortality. With the increasing number of COVID-19 pneumonia survivors, several long-term changes may persist, including abnormal imaging of lung parenchyma. In addition to the clinical course, it is vital to follow up on pulmonary imaging during the post-infectious period, which is not routinely required in other common pulmonary diagnoses. Computed tomography (CT) scan of the chest is an effective and diagnostic tool for pneumonia which gives an insight into structural abnormalities within the lungs, complications, and possible progression of the disease. Several studies have monitored COVID-19 pneumonia and its complications using serial CT chest imaging from the initial phase of infection, hospitalization, and post-discharge. Nonetheless, long-term follow-up imaging data in post-COVID-19 is still limited. We have summarized the findings utilizing a systematic review of the literature regarding COVID-19 pneumonia imaging, including long-term follow-up.

Coronavirus Disease 2019-Induced Tracheomegaly: A Case Report.

Tracheomegaly is a medical condition where the tracheal diameter is greater than the upper limits of normal. Tracheomegaly can be classified as primary or secondary. Primary tracheomegaly is usually congenital. Secondary tracheomegaly can be due to multiple causes, including connective tissue disease, infections, autoimmune diseases like sarcoidosis, and prolonged mechanical ventilation. Here, we describe the first reported case of tracheomegaly secondary to coronavirus disease 2019 (COVID-19) pneumonia and COVID-induced interstitial lung disease (ILD). While many cases of tracheomegaly are asymptomatic, patients can have symptoms like cough, dyspnea, hemoptysis, or even respiratory failure. Tracheomegaly is associated with a higher risk of recurrent lower respiratory tract infections, chronic cough, bronchiectasis, and tracheobronchomalacia. Early recognition of COVID-19-induced tracheomegaly can help initial early management and reduce the incidence of infections.

Restrictive Lung Disease in Patients With Subclinical Coronavirus Infection: Are We Bracing Ourselves for Devastating Sequelae?

The coronavirus disease 2019 (COVID-19) pandemic has affected millions of people worldwide. The manifestations of COVID-19 infection can range from being asymptomatic to developing severe acute respiratory distress syndrome (ARDS). Here, we present a case series of five patients who were either asymptomatic or had very mild symptoms of COVID-19 infection upon diagnosis. These patients neither required a visit to the emergency department (ED) nor did they need to be hospitalized but became symptomatic and were found to have interstitial lung disease four to eight weeks after a COVID-19 diagnosis. Thus, it is imperative that we routinely follow up patients with a subclinical COVID 19 infection besides those who were symptomatic. We may be witnessing a silent surge and new-onset interstitial lung disease (ILD) as sequelae of COVID 19 infection.
