Pleural amyloidosis imitating pleural malignancy.
CT chest performed to investigate dyspnea and malaise in an 83 year old man demonstrated bilateral circumferential pleural thickening highly suspicious for pleural mesothelioma or metastatic pleural malignancy. Histopathology of a subsequent pleural biopsy returned a diagnosis of pleural amyloid. This case identifies pleural amyloid as a rare differential consideration for diffuse pleural thickening; the difficulties in distinguishing pleural amyloid from pleural malignancy are highlighted.
