Pleural Empyema ultrasound case study

CASE–1

Clinical History

7y old Patient was referred for thoracic ultrasound due to fever, pleuritic chest pain, cough, dyspnea, or persistent right-sided pleural effusion. There may be a history of pneumonia, thoracic surgery, trauma, or tuberculosis.

Ultrasound Findings

Ultrasound examination demonstrates a moderate to large right pleural collection with complex internal echogenicity. Multiple internal septations and fibrin strands are noted within the pleural fluid. The collection appears loculated with associated pleural thickening. The adjacent right lung is compressed with partial atelectatic changes. No obvious solid pleural mass is identified. Color Doppler demonstrates no internal vascularity within the pleural collection.

Report Line

A complex loculated pleural fluid collection is seen in the right pleural cavity, measuring approximately ____ × ____ mm. Internal echoes, fibrin strands, and multiple septations are present with associated pleural thickening. Adjacent compressive atelectatic changes are noted in the right lung. No internal vascularity is demonstrated on color Doppler imaging. Findings are suggestive of right-sided empyema.

Impression

Features are consistent with right pleural empyema with complex septated pleural collection and adjacent compressive atelectatic changes.

Key Learning Points

• Empyema is an infected pleural fluid collection and represents a complicated parapneumonic effusion.
• Ultrasound typically demonstrates complex pleural fluid with internal echoes, fibrin strands, and septations.
• Pleural thickening and loculations strongly favor empyema over simple pleural effusion.
• Color Doppler usually shows no internal vascularity within the pleural collection.
• Adjacent lung compression or atelectatic changes are commonly present.
• Ultrasound is valuable for detecting septations and guiding diagnostic aspiration or chest tube placement.
• Differential diagnoses include complicated parapneumonic effusion, hemothorax, malignant pleural effusion, and chronic organized pleural collection.

Recommendation

Urgent clinical correlation is recommended. Correlate with inflammatory markers and pleural fluid analysis. Image-guided thoracentesis or chest tube drainage should be considered when clinically indicated. Contrast-enhanced CT of the thorax may be performed to assess the extent of empyema and evaluate associated pulmonary pathology.

X-ray Correlation

Chest radiograph (PA/AP and lateral views) typically demonstrates a moderate to large right pleural opacity with a meniscus or lenticular configuration. In loculated empyema, the opacity may appear lentiform or biconvex rather than freely layering. Blunting of the right costophrenic angle is present with adjacent right lower lobe compressive atelectatic changes or consolidation. Pleural thickening may be evident in chronic cases. Air-fluid level may be seen if a bronchopleural fistula or gas-forming organism is present.

X-ray Findings

Chest radiograph demonstrates a homogeneous pleural-based opacity occupying the lower to mid right hemithorax with obliteration of the right costophrenic angle. The collection has a lenticular configuration suggestive of loculated pleural fluid. Adjacent right lower lung compressive atelectatic changes are noted. No evidence of pneumothorax is seen. Cardiomediastinal silhouette is within normal limits or mildly shifted depending on the volume of the pleural collection.

X-ray Report Line

Homogeneous pleural-based opacity is seen involving the right lower hemithorax with blunting of the right costophrenic angle. The opacity demonstrates a lenticular/loculated appearance with adjacent compressive atelectatic changes of the right lower lobe. Findings are highly suggestive of a loculated right pleural empyema. Correlation with thoracic ultrasound and contrast-enhanced CT chest is recommended for further evaluation.
