Abstract:
An 88-year-old man with a history of myocardial infarction, non-valvular atrial fibrillation and hypothyroidism was admitted to our hospital with a diagnosis of coronavirus disease. On admission, he had hypoxemia, with peripheral blood oxygen saturation at 95% on 5 L of oxygen via face mask ventilation. Chest computed tomography (CT) showed bronchial wall thickening and emphysema in both lungs, ground-glass opacities and high-attenuation areas in the bilateral lower lungs. After hospitalization and treatment, hypoxemia improved; however, chest CT showed marked progression of the high-attenuation areas, suggestive of pulmonary ossification (PO) in both lower lungs. The patient was transferred to a rehabilitation hospital; however, hypoxemia had improved at the time of discharge and chest CT showed marked improvement in the findings suggestive of PO.

COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
