CTICasesTuberculous pleuritis
Imaging findings
Chest CT and PET scan in a 39-year-old woman show a unilateral pleural effusion with associated nodular pleural thickening, mediastinal and hilar lymphadenopathy, and metabolic activity on PET. Biopsy of a lymph node showed necrotizing granulomas and acid-fast bacilli, confirming tuberculosis.
Key takeaways
Tuberculous pleuritis can present as a unilateral pleural effusion with nodular pleural thickening and hilar/mediastinal lymphadenopathy, mimicking pleural mesothelioma or metastatic malignancy. A high index of suspicion and pleural or node biopsy is required to distinguish it.
