Abstract
Probable or possible multiple system atrophy (MSA) was diagnosed on strict clinical criteria in 42 patients: 20 with combined parkinsonism and cerebellar ataxia, 9 with striatonigral degeneration (SND) and 13 with olivopontocerebellar atrophy (OPCA). All patients were then studied with 0.5 and/or 1.5 Tesla magnetic resonance (MR) units. MR imaged putaminal abnormalities in all 9 patients with SND and posterior fossa obnormalities consistent with OPCA in all 13 patients with this diagnosis. Of the 20 patients with parkinsonism and cerebellar involvement, classified as probable MSA, 7 presented putaminal abnormalities only, 3 abnormalities consistent with OPCA only and 10 a combination of both. These findings show strong MRI support for the clinical diagnosis of MSA.
Sommario
In base a precisi criteri clinici 42 pazienti furono riconosciuti affetti da atrofia multisistemica (MSA) probabile o possibile. Venti pazienti presentavano parkinsonismo e atassia cerebellare; in 9 fu fatta diagnosi di degenerazione strio-nigrica (SND) e in altri 13 di atrofia olivopontocerebellare (OPCA). Tutti i pazienti furono sottoposti a risonanza magnetica 0.5 e/o 1.5 T. La RM mostrava alterazioni nei putamen nei 9 pazienti con SND e alterazioni in fossa posteriore come attese nell'OPCA nei 13 casi diagnosticati affetti da OPCA. In 10 dei 20 pazienti con parkinsonismo e atassia cerebellare le alterazioni nei putamen e in fossa posteriore erano associate. I nostri dati confermano che la RM è un supporto diagnostico fondamentale nella diagnosi di MSA.
