Discussion: A large part of both clinical and subclinical lesions found in our daily work are benign and correspond with fibrocystic changes (FCC). This entity is complex and part exhibit traits that define characteristically in MRI and diagnose correctly, but there is another small group of changes that can take the image aspect of cancer. From a complex case, we review the main aspects of the...
BACKGROUND AND PURPOSE A full appreciation of the presence of cerebral vascular lesions in cognitively impaired patients can be ultimately reached at the neuropathological level. However, there are no detailed guidelines regarding what neuropathologists should look for at autopsy in cases of suspected vascular dementia or vascular cognitive impairment. We aimed at surveying the postmortem neuro...
AIMS Loss-of-function mutations in GBA1, which cause the autosomal recessive lysosomal storage disease, Gaucher disease (GD), are also a key genetic risk factor for the α-synucleinopathies, including Parkinson's disease (PD) and dementia with Lewy bodies. GBA1 encodes for the lysosomal hydrolase glucocerebrosidase and reductions in this enzyme result in the accumulation of the glycolipid substr...
Three patients with homocystinuria due to cystathionine beta-synthase deficiency who developed progressive generalised dystonia are described. Although cerebrovascular thrombosis is usually thought to be responsible for neurological dysfunction in homocystinuric patients, neuropathological studies in one case and clinical and radiological evidence in the other two suggested that dystonia was no...
Chronic brainstem encephalitis with mental symptoms and ataxia: report of three cases with necropsy.
Three necropsied cases of chronic, sporadic brainstem encephalitis of unknown aetiology are presented. Since their outstanding symptoms were dementia and ataxia of a progressive nature, a noninflammatory disease of the central nervous system was suspected. Neuropathological studies showed chronic inflammatory changes mainly in the brainstem without the presence of inclusion bodies or viral part...
Two patients with levodopa-responsive Parkinson's syndrome had numerous cortical and striatal senile plaques and some neurofibrillary tangles at necropsy. In addition neurons in the pars compacta of the substantia nigra were severely depleted but there were no Lewy bodies or other neuropathological changes to account for parkinsonism. Neither patient was demented. These pathological findings ha...
