CTICasesPleural Sarcoidosis
Imaging findings
Serial chest CTs show a chronic right pleural effusion and nodular/lobulated pleural thickening, associated with classic lung parenchymal perilymphatic nodularity. Pleural biopsy confirmed non-necrotizing granulomas of sarcoidosis in a patient with CLL.
Key takeaways
Pleural involvement is a rare manifestation of sarcoidosis, occurring in less than 1% of patients. It presents as an exudative effusion and pleural thickening, which must be histologically differentiated from lymphoma or tuberculosis.
