RESUMEN
@#The objective of this case report is to highlight the role of Iodine-131 metaiodobenzylguanidine (MIBG) cardiac scintigraphy in discriminating Dementia with Lewy Bodies (DLB) from other neurodegenerative diseases such as Alzheimer’s Disease. This patient is a known case of Parkinson’s disease and has been treated as such since 2011. However, the patient also concurrently deals with visual hallucinations and because of this, the patient’s attending neurologist wanted to rule in the diagnosis of DLB rather than AD. Hence, an I-131 MIBG cardiac scan was requested in order to support the diagnosis of DLB. The use of I-131 MIBG cardiac scintigraphy as a diagnostic tool for diagnosing Lewy Body Dementia is not prevalent and to our knowledge, this was the first time in the country that this procedure was done (December 9, 2019).
