Chest X-Ray Interpretation
Patient: Shiv Raj, Male, 41 years
Date: 13-Jul-2026, 11:03
Department: Respiratory Medicine, J.L.N. Medical College, Ajmer
View: AP (Anteroposterior) projection
Technical Adequacy
- AP projection, likely semi-erect or supine positioning
- Multiple ECG monitoring leads visible as circular radiopaque artifacts over bilateral lung fields and mediastinum - these are external and should not be mistaken for pathology
- Horizontal line artifact crossing the upper chest
Findings
Left Hemithorax - Major Finding
- Large left-sided pleural effusion is the dominant finding
- Dense, homogeneous opacity occupying the lower half of the left hemithorax
- Classic meniscus sign - upward-curving upper border along the lateral chest wall
- Complete obliteration of the left costophrenic angle
- Left heart border is silhouetted (not visible) due to the adjacent fluid
- Left hilum is obscured by pleural fluid
Right Lung
- Right lung field is largely clear
- Mild diffuse reticular (net-like) interstitial markings - may suggest mild underlying parenchymal changes or chronic airway disease
- Right costophrenic angle is sharp and clear - no effusion on the right
Mediastinum and Trachea
- Trachea shows subtle deviation toward the right - consistent with mass effect from the large left effusion
- No obvious mediastinal widening
- Cardiac size difficult to assess on AP view; does not appear massively enlarged
Bony Structures
- Ribs, clavicles, and shoulder girdles appear intact
- No obvious fractures or lytic lesions seen
Impression
Moderate-to-large left-sided pleural effusion
Differential Diagnosis (Given Clinical Context - Respiratory Medicine, 41M)
Given the department is Respiratory Medicine and the patient's age/sex, the leading causes to investigate include:
| Priority | Cause | Clues to Look For |
|---|---|---|
| 1 | Tuberculosis (parapneumonic/exudative) | Most common cause of unilateral exudative effusion in this age group in India |
| 2 | Parapneumonic effusion / empyema | Fever, elevated WBC, consolidation in right lung |
| 3 | Malignancy (primary lung or metastatic) | Smoking history, weight loss, lymphadenopathy |
| 4 | Transudative causes (heart failure, hypoalbuminemia, cirrhosis) | Bilateral effusions more typical; less likely given unilateral |
| 5 | Inflammatory / CTD | Rheumatoid, SLE - less common |
Recommended Next Steps
- Chest ultrasound - to confirm and guide diagnostic/therapeutic thoracentesis
- Pleural fluid analysis (Light's criteria: protein, LDH, glucose, pH, cytology, ADA for TB, culture)
- CT chest with contrast - to evaluate underlying lung parenchyma, mediastinum, and pleural surface once some fluid is drained
- Sputum AFB / CBNAAT if TB is suspected
- Blood workup - CBC, ESR, CRP, LFT, RFT, serum protein/albumin
