Summary
This case study highlights a chronic obstructive pulmonary disease (COPD) exacerbation misdiagnosed as lung cancer due to nodular opacities. Computed tomography (CT) is crucial for differentiating these conditions before invasive procedures.
Area of Science:
- Pulmonology
- Medical Imaging
- Infectious Diseases
Background:
- A 67-year-old male with a history of chronic obstructive pulmonary disease (COPD) and heavy smoking presented with severe dyspnea and productive cough.
- Clinical presentation suggested an exacerbation of COPD with global respiratory failure, marked by cyanosis, barrel chest, and diffuse wheezing.
Observation:
- Initial chest radiography revealed multiple nodular opacities, raising suspicion for bronchial carcinoma with metastases.
- Computed tomography (CT) demonstrated fluid-filled bronchi, and bronchoscopy identified significant sticky secretions, leading to the isolation of Klebsiella oxytoca and Haemophilus influenzae.
Findings:
- Severe hypoxemia (pO2 48 mm Hg) and hypercapnia (pCO2 46 mm Hg) were noted, along with reduced lung function parameters.
- Antibiotic treatment with amoxicillin and clavulanic acid resulted in rapid clinical improvement and normalization of chest x-ray within 10 days.
Implications:
- This case underscores the importance of computed tomography (CT) in evaluating nodular pulmonary opacities on chest radiographs to avoid misdiagnosis.
- CT imaging should precede bronchoscopy when differentiating between infectious processes and malignancy in patients with COPD presenting with such findings.
