Summary
Early coronavirus disease 2019 (COVID-19) may present as a common upper respiratory infection. Chest imaging findings suggestive of COVID-19 can evolve, necessitating careful evaluation of worsening symptoms.
Area of Science:
- Pulmonology
- Infectious Diseases
- Radiology
Background:
- Coronavirus disease 2019 (COVID-19) is a novel infectious disease.
- Initial symptoms can mimic common upper respiratory infections.
- Radiographic findings may not be immediately apparent.
Purpose of the Study:
- To highlight the initial presentation of COVID-19.
- To emphasize the importance of serial imaging in suspected cases.
- To discuss the spectrum of chest imaging findings in COVID-19.
Main Methods:
- Case report of a 48-year-old male with worsening respiratory symptoms.
- Review of initial urgent care presentation and subsequent emergency department visit.
- Analysis of chest radiograph and computed tomography findings.
Main Results:
- Initial presentation was consistent with an upper respiratory infection.
- Chest radiograph at initial presentation was negative.
- Worsening shortness of breath prompted further evaluation and imaging.
Conclusions:
- COVID-19 can present insidiously with non-specific symptoms.
- Chest imaging, including CT, plays a crucial role in diagnosing COVID-19.
- Radiographic findings may evolve over time in COVID-19 patients.

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
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...

Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
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...
