Amiodarone toxicity presenting as pulmonary mass and peripheral neuropathy: the continuing diagnostic challenge
1Department of Internal Medicine A, Bnai-Zion Medical Centre and Rappaport Family Faculty of Medicine, Technion-Israel Institute of Technology, Haifa, Israel.
Abstract:
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.
