  • Abstract
  • Look Inside

Non-hereditary olivo-ponto-cerebellar atrophy(OPCA) and striato-nigral degeneration (SND) have been looked upon as a single disease entity called multisystem atrophy (MSA) by Oppen-heimer. This study revealed that both intracytoplas-mic argyrophilic inclusions (AI) in pontine neurons and glial (argyrophilic) cytoplasmic inclusions (GCIs) widely distributed in the CNS are characte-ristics of MSA.

Materials : a) 12 cases with MSA, b) 16 cases with autosomal dominant (AD) form of spinocere-bellar degeneration (SCD) : AD form of OPCA 5 cases, Joseph disease 4 cases, AD-dentatorubro-pallidoluysian atrophy (Naitoh & Oyanagi's form) 6 cases, AD-spastic ataxia (Brown) 1 case, c) 4 cases with autosomal recessive (AR) form of SCD : AR form of OPCA 1 case, myoclonic epilepsy with ragged-red fibers (MERRF) 1 case, complicated form of spastic paraplegia 2 cases, d) 6 cases with non-hereditary SCD including intoxications : late cortical cerebellar atrophy 1 case, alcoholic cerebel-lar degeneration 2 cases, phenytoin-induced cerebel-lar degeneration 1 case, neuroleptic malignant syn-drome 1 case, and e) 27 cases with other neuropsy-chiatric diseases : Alzheimer disease 20 cases, pro-gressive supranuclear palsy 5 cases, schizophrenia 2 cases.

Method : We examined 10 μ-thick paraffin sec-tions stained with HE, Kluver-Barrera, Bodian, Holzer, Gallyas, and Bielschowski methods.

Results : AI in pontine neurons were found only in two cases of MSA. Interestingly no AI could be detected even in cases with AD form of OPCA showing mild degeneration in the pontocerebellar system. On the other hand, GCIs were found in all cases with MSA irrespective of the degree of degen-eration in the olivo-ponto-cerebellar or striato-nigral system. However, there was no GCIs in cases with other form of SCD and other neuropsychiatric diseases. Gallyas stain was the best method for detecting GCIs. GCIs were widely distributed in the CNS except for superficial layers of the cerebral cortex, the cerebellar cortex, and the dorsal colum of the spinal cord. There were also many GCIs in the putamen, pontine base, and cerebellar white matter, even though these sites were well preserved.
