RT Journal Article SR Electronic T1 Amiodarone toxicity presenting as pulmonary mass and peripheral neuropathy: the continuing diagnostic challenge JF Postgraduate Medical Journal JO Postgrad Med J FD The Fellowship of Postgraduate Medicine SP 73 OP 75 DO 10.1136/pgmj.2005.040105 VO 82 IS 963 A1 Azzam, I A1 Tov, N A1 Elias, N A1 Naschitz, J E YR 2006 UL http://pmj.bmj.com/content/82/963/73.abstract AB 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.
