Diagnostic Tests for Pneumonia

Chest X-ray (Posteroanterior View) – Indications, Interpretation, and Findings

Pneumonia is a respiratory condition characterized by inflammation of the lung parenchyma, often caused by bacterial, viral, or fungal infections. The diagnosis of pneumonia frequently involves radiographic imaging, with chest X-ray being a primary modality.

Indications for Chest X-ray in Pneumonia Diagnosis

• Persistent fever and productive cough
• Dyspnea and pleuritic chest pain
• Suspicion of pulmonary infection despite normal auscultatory findings

Interpretation of Posteroanterior Chest X-ray

The posteroanterior (PA) view is the standard approach for evaluating lung pathology. The interpretation involves assessing lung fields, cardiac silhouette, diaphragm, and pleural spaces.

Radiological Findings in Pneumonia

• Consolidation: Homogeneous opacity with air bronchograms, indicative of alveolar filling
• Interstitial Patterns: Reticular or nodular opacities, seen in atypical pneumonia
• Pleural Effusion: Blunting of costophrenic angles or fluid accumulation
• Cavitation: Occasional feature in necrotizing pneumonia or lung abscess

Conclusion

Chest X-ray remains an essential diagnostic tool for pneumonia, aiding in early detection and monitoring disease progression. Correlating radiographic findings with clinical symptoms ensures accurate diagnosis and appropriate management.
