A 64 year old man receiving long term amiodarone treatment presented with dyspnea, cough, and weight loss. Radiographs and computed tomography showed a lung mass with associated multiple pulmonary nodules. Biopsies of the pulmonary mass showed foamy histiocytes without malignant cells. However, findings on FDG-PET scan were consistent with a malignant tumour. These findings on computed tomography and PET scan and the unusually late resolution of the pulmonary lesions after withdrawal of amiodarone treatment posed a challenging diagnostic problem.
一名接受长期胺碘酮治疗的64岁男性出现呼吸困难、咳嗽和体重减轻。X光片和计算机断层扫描显示肺部有肿块及多个相关肺结节。肺部肿块活检显示为泡沫状组织细胞,未见恶性细胞。然而,氟脱氧葡萄糖正电子发射断层扫描(FDG-PET)结果与恶性肿瘤相符。计算机断层扫描和PET扫描的这些结果,以及胺碘酮停药后肺部病变异常延迟消退的情况,构成了一个具有挑战性的诊断难题。
