CTICasesDesmoplastic Pleural Mesothelioma mimicking Empyema
Imaging findings
CT in a patient treated for a paramnemonic effusion/empyema shows progressive, lobulated, and circumferential pleural thickening and effusion, confirmed on biopsy as desmoplastic pleural mesothelioma.
Key takeaways
Desmoplastic pleural mesothelioma is a rare, fibrous variant of mesothelioma that can mimic chronic empyema or pleural sclerosis. Circumferential, nodular pleural thickening and involvement of the mediastinal pleura are key clues favoring malignancy.
