Rapid developing empyema by group F beta Streptococcus anginosus group.

Area of Science:

• Infectious Diseases
• Pulmonology
• Radiology

Background:

• Pleural effusion and pulmonary nodules can present with diverse etiologies.
• Streptococcus anginosus, particularly group F, is an uncommon cause of severe thoracic infections.

Observation:

• A 43-year-old male presented with pleuritic chest tightness and shortness of breath, accompanied by dental caries and chest wall tenderness.
• Initial CT pulmonary angiography revealed multiple pulmonary nodules and pleural thickening. Subsequent CT scans showed right lower lobe consolidation and left-sided pleural effusion with atelectasis.

Findings:

• Leukocytosis was noted on complete blood count.
• Pleural fluid analysis identified group F beta-haemolytic Streptococcus anginosus.
• The patient received intravenous ceftaroline and underwent CT-guided chest tube insertion for drainage.

Implications:

• Prompt diagnosis and aggressive management, including antibiotics and pleural space drainage, are crucial for favorable outcomes in thoracic infections caused by Streptococcus anginosus.
• This case highlights the importance of considering bacterial infections in the differential diagnosis of complex pulmonary and pleural abnormalities.
• Early intervention with targeted antibiotic therapy and source control can prevent severe complications and facilitate patient recovery.
