CT Chest Detects COVID-19 Pneumonia in a Symptomatic Patient
Introduction: Imaging in the COVID-19 Era
COVID-19, caused by the SARS-CoV-2 virus, primarily affects the respiratory system. While RT-PCR remains the gold standard for diagnosis, CT chest imaging plays a crucial role in evaluating disease severity, especially in symptomatic patients. This case highlights the diagnostic value of CT imaging during the pandemic.
Case Presentation
A 50-year-old man presented with fever, dry cough, and shortness of breath for 5 days. He had a known exposure to a COVID-positive co-worker. His oxygen saturation was 91% on room air. Initial nasopharyngeal swab for RT-PCR was pending at presentation.
Initial Workup
- Vitals: HR 104 bpm, BP 122/78 mmHg, Temp: 101.3°F
- CBC: Mild lymphopenia
- CRP and D-dimer elevated
- Chest auscultation: Bilateral basal crackles
- Due to worsening breathlessness, a high-resolution CT (HRCT) chest was ordered.
CT Chest Findings
- Bilateral **ground-glass opacities (GGOs)** with peripheral and subpleural distribution
- Patchy consolidations in the posterior lower lobes
- No pleural effusion or lymphadenopathy
- CT Severity Score: 13/25 (moderate involvement)
Diagnosis: COVID-19 Pneumonia
Based on clinical symptoms and CT findings, a presumptive diagnosis of COVID-19 pneumonia was made while awaiting RT-PCR confirmation.
Management
- Patient was admitted to a COVID-19 isolation unit
- Supportive therapy with antipyretics, oxygen, and fluids
- Started on steroids and anticoagulants as per local protocol
- Monitored for oxygen requirement escalation
- RT-PCR result returned positive the next day
Why CT Was Useful
- CT detects typical imaging patterns even before RT-PCR turns positive
- Helps assess extent and severity of lung involvement
- Guides early intervention and triage, especially when RT-PCR delays occur
Patient Outcome
- Improved with supportive therapy
- Oxygen saturation normalized by day 7
- Discharged on day 10 with home quarantine advice
Conclusion: CT Imaging Supports Early COVID-19 Detection
In symptomatic patients, CT chest helps bridge diagnostic delays and evaluates severity in COVID-19 cases. This case demonstrates how early imaging informed timely isolation and treatment in a potentially contagious patient.
