Here is a detailed radiological analysis of this PA chest X-ray:
PA Chest X-Ray - Radiological Report
Key Finding: Right Thoracoplasty (Post-Tuberculous)
The most striking and defining finding is a right thoracoplasty - a historical surgical procedure involving the deliberate resection/collapse of the upper right ribs (approximately ribs 1-5). This was classically performed for cavitary pulmonary tuberculosis (pre-antibiotic era surgery).
Systematic Analysis
Bones & Chest Wall
- Right thoracoplasty: Partial rib resection with crowding, deformity, and regeneration of the upper right ribs
- Right clavicle and shoulder girdle: Elevated and deformed secondary to chest wall collapse
- Thoracic spine: Mild degenerative change with slight dextroscoliosis (likely a consequence of asymmetric chest wall mechanics)
- Left clavicle and shoulder: Intact
Right Lung
- Severe volume loss in the right upper lobe with dense fibroproductive scarring and parenchymal distortion beneath the thoracoplasty site
- Compensatory hyperinflation of the right middle and lower zones
- Marked apical pleural thickening consistent with chronic fibrothorax / prior tuberculous pleuritis
- Right hemidiaphragm is significantly elevated due to cicatrization/volume loss
Left Lung
- A well-circumscribed, round-to-oval nodule/mass (~2-3 cm) in the peripheral/subpleural region of the left mid-lung zone - this is a significant finding requiring further investigation
- The remainder of the left lung is clear with normal bronchovascular markings
- Left costophrenic angle is sharp (no effusion)
Cardiac Silhouette & Mediastinum
- Mediastinal shift to the right due to right-sided volume loss and cicatrization - this is expected with thoracoplasty
- Heart size is difficult to assess due to the shift but does not appear grossly enlarged
- No pneumothorax
Diaphragm
- Right hemidiaphragm: Elevated (secondary to right lung volume loss)
- Left hemidiaphragm: Normal position; gastric bubble visible beneath it
- Both costophrenic angles are clear - no pleural effusion bilaterally
Summary & Clinical Interpretation
| Finding | Significance |
|---|---|
| Right thoracoplasty | Prior surgical treatment of cavitary TB |
| Right upper lobe fibrosis + pleural thickening | Post-tuberculous sequelae / fibrothorax |
| Mediastinal shift right + elevated R. hemidiaphragm | Expected compensatory changes from volume loss |
| Left mid-lung nodule/mass (~2-3 cm) | NEW/ACTIVE concern - requires CT thorax |
| Dextroscoliosis | Secondary to chest wall asymmetry |
Differential for the Left Lung Nodule
Given the background of prior TB:
- Post-primary TB nodule / tuberculoma (most likely given context)
- Reactivation TB - active disease in the contralateral lung
- Primary lung carcinoma - must be excluded, especially if the patient is older or a smoker
- Metastatic deposit
- Pleural-based lesion (e.g., localized mesothelioma, loculated effusion, pleural plaque)
- Fungal granuloma (e.g., aspergilloma in a scarred cavity)
Recommended Next Steps
- CT thorax with contrast - to characterize the left mid-lung nodule (margins, internal characteristics, lymphadenopathy, cavitation)
- Sputum for AFB smear and culture - rule out active TB
- Comparison with prior imaging - growth rate of the nodule is diagnostically valuable
- Bronchoscopy ± CT-guided biopsy if the nodule is suspicious for malignancy or cannot be classified on CT
