CTICasesPleural and Peritoneal Tuberculosis
Imaging findings
Chest CT shows a moderate right-sided pleural effusion with mild pleural membrane thickening. Abdominal CT shows free peritoneal fluid without focal organ lesions. The patient is an immigrant from Kenya, and pleural biopsy subsequently grew Mycobacterium tuberculosis.
Key takeaways
Extrapulmonary tuberculosis can present as isolated pleural effusion and ascites (peritoneal TB) without active parenchymal lung disease. Diagnostic tap and pleural or peritoneal biopsy are critical for confirmation. High index of suspicion is required in patients from endemic areas.
