Diagnosis With Brief Discussion
- Diagnosis
- Diffuse large B-cell lymphoma associated chronic inflammation (Pyothorax-associated lymphoma)
- Radiologic Findings
- Initial chest radiogram and CT images show large amount of right pleural loculated fluid collection with calcified wall thickening and air-fluid level, which represent chronic empyema. Additionally, right pleura and wall of empyema show diffuse mild nodular thickening with enhancement. Thoracostomy was done.
After 6 weeks, chest radiogram and CT images shows aggravation of thickening and enhancement of right pleura and wall of empyema. VATS lung decortication was done and empyema peel biopsy was confirmed as diffuse large B-cell lymphoma, associated with chronic inflammation.
And PET-CT scan shows multiple hypermetabolic lesions along right pleura and empyema wall. The patient had history of tuberculous pleuritis in 1987. EBV VCA immunoglobuin G was positive.
