Abstract
ABSTRACT
A 77-year-old man with parkinsonism was referred to the department of neurology for further examination. Cardiac 123I-MIBG scintigraphy unexpectedly showed strong uptake in the left shoulder, suggestive of MIBG-avid tumors including paraganglioma. MRI revealed multiple nodules suggestive of lymphoma. A biopsy was performed, which led to the pathological diagnosis of diffuse large B-cell lymphoma. Cardiac MIBG scintigraphy sometimes shows unexpected findings outside the mediastinum. In addition, lymphoma should also be added to the list of differential diagnoses for MIBG-positive tumors.
