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.
对一名83岁男性因呼吸困难和全身不适进行的胸部CT检查显示双侧环形胸膜增厚，高度怀疑为胸膜间皮瘤或转移性胸膜恶性肿瘤。随后胸膜活检的组织病理学检查结果为胸膜淀粉样变。该病例表明胸膜淀粉样变是弥漫性胸膜增厚的一种罕见鉴别诊断；强调了区分胸膜淀粉样变与胸膜恶性肿瘤的困难。
