Chest X-Ray Interpretation
Patient: Mrs. R. Kalaiselvi, 53 years | Date: 2026-07-09 | View: PA (Posterior-Anterior)
Technical Adequacy
- Projection: PA view, adequate centering
- Inspiration: Suboptimal - diaphragm slightly elevated, fewer than 9-10 posterior ribs visible above the diaphragm; this causes mild crowding of bronchovascular markings
- Rotation: Minimal - clavicular heads are reasonably equidistant from the spinous processes
Findings
Lung Fields
Right lung (the patient's right = viewer's LEFT on PA film):
- Large, dense homogeneous-to-heterogeneous opacity occupying the right lower and mid zones
- Positive silhouette sign: the right heart border and right hemidiaphragm are obscured, indicating pathology in the right middle lobe and/or lower lobe (anterior segments)
- Meniscus sign at the lateral aspect of the opacity - strongly suggestive of an associated right pleural effusion
- Superimposed patchy airspace consolidation in the right mid-lung field
- Right costophrenic angle is blunted/obliterated
Left lung:
- Clear lung fields throughout
- Normal bronchovascular markings
- Left costophrenic angle is sharp and well-defined - no effusion
- Left hemidiaphragm is normal in position and contour
Cardiac Silhouette & Mediastinum
- Left heart border: normal contour
- Right heart border: obscured by adjacent opacity (silhouette sign)
- Overall cardiac size appears within normal limits
- Trachea is midline - no mediastinal shift (suggesting the effusion and any atelectasis are roughly balancing each other)
Bony Structures & Soft Tissues
- Ribs, clavicles, and scapulae are intact - no lytic or blastic lesions, no acute fractures
- Mild degenerative changes in the lower cervical spine
- Bilateral breast shadows present, consistent with female patient
- No subcutaneous emphysema
Summary & Impression
Right lower and mid-zone consolidation with associated moderate right-sided pleural effusion (parapneumonic effusion)
The most likely diagnosis is right-sided pneumonia (community-acquired pneumonia, likely right lower lobe ± right middle lobe) complicated by a parapneumonic effusion. In a 53-year-old female, differential diagnoses include:
- Bacterial pneumonia with parapneumonic effusion (most likely)
- Empyema (if effusion is exudative/infected)
- Malignant pleural effusion with collapse/consolidation (less likely but must be excluded if there is no fever or if the effusion fails to resolve)
- Tuberculous pleuritis with underlying consolidation
Recommendations
| Action | Rationale |
|---|---|
| Correlate clinically | Fever, cough, pleuritic chest pain, dyspnea, oxygen saturation |
| Blood tests | CBC, CRP/ESR, blood cultures, LDH |
| Chest ultrasound | Confirm effusion, assess for loculation, guide diagnostic/therapeutic thoracentesis |
| Sputum culture & sensitivity | Identify causative organism |
| Thoracentesis (if significant effusion) | Pleural fluid analysis: Light's criteria (exudate vs. transudate), glucose, LDH, cytology, culture |
| Follow-up CXR at 4-6 weeks | Confirm resolution after antibiotic therapy; persistent opacity warrants CT chest |
