[123I-metaiodobenzylguanidine myocardial scintigraphy in the differential diagnosis of patients with parkinsonian syndromes -- case reports].
The aim of this study is to present a clinical role for 123I-metaiodobenzylguanidine (MIBG) myocardial scintigraphy in the differential diagnosis in patients with parkinsonian syndromes. We present a 51-year-old woman with parkinsonian syndrome and syncope occurrence. She reproduced spontaneous syncope in the tilt test. We present also a 60-year-old man with parkinsonian syndrome and syncope and presyncope occurrence. He also reproduced spontaneous syncope in the tilt test. Cardiac 123I-MIBG scintigraphy was performed in both patients. In the former patient, the H/M ratio of MIBG uptake was within normal ranges, in the latter, it was abnormally impaired. The results of the 123I-MIBG cardiac scintigraphy confirm results of the other studies. In the patient with Parkinson's disease the H/M ratio of MIBG uptake was abnormally impaired. The patient with the multiple system atrophy was within normal ranges.
