Two families have been described previously with the features of an autosomal dominant familial cerebral amyloid angiopathy with nonneuritic plaque formation. The clinical features of the cases were dementia, spastic paralysis and ataxia. It has now been established that both families were descended from a common ancestor and the case histories of 26… (More)
A series of 241 gliomas (astrocytomas, oligodendrogliomas, glioblastomas, and subependymal giant-cell astrocytomas) was studied. This represents all the gliomas examined post mortem over 25 years at one hospital. Two hundred and one cases (85%) were apparently solitary tumors; of the 40 cases with multiple tumor foci, 23 (9.5%) were true multicentric… (More)
The relationship between plaque pathology and disease duration was examined in 15 patients with multiple sclerosis who died early in the course of their illness. Myelin-stained sections revealed that most plaques examined in patients who died during the first month of their illness showed evidence of ongoing myelin destruction accompanied by a loss of… (More)
From a series of 66 cases of central nervous system ependymomas, three cases of well differentiated ependymoma of the cauda equina are described. These tumors recurred and spread to produce intracranial deposits. No extraneural lesions were found.
A series of cases of astrocytoma of differing cell composition and degree of malignancy was examined for the presence of reactive perivascular cuffing. Only surgical biopsy material was used. A correlation was made between perivascular lymphocyte cuffing and the presence of neoplastic astrocytes of the gemistocytic type.
A case of cerebellar medulloblastoma with transitional features towards malignant fibrillary astrocytoma is described. In the cerebellum the tumour is characterised by extensive subpial infiltration with cells of undifferentiated type, and the astrocytic component could only be identified by a positive glial fibrillary acidic protein reaction. In the… (More)
We studied by immunohistochemistry the features of differentiation in 24 desmoplastic and 16 classic medulloblastomas (median patient ages, 18 and 6.5 years, respectively) with the use of a panel of cytoskeletal and synaptosomal markers. A distinctive pattern of immunoreactivity with a series of monoclonal antibodies (Mabs) was documented in the polar tumor… (More)
Recent autopsy studies suggest that remyelinated shadow plaques located in otherwise intact white matter are the outcome of a previous single episode of acute demyelination. In the present study, of 98 remyelinated plaques examined in 15 patients with multiple sclerosis who died between 27 days and 5 years after clinical onset, 15 showed evidence of a… (More)
The dynamics of primary progressive multiple sclerosis differ from those of the more common secondary progressive form. The observation by MRI that the frequency of enhancement with gadolinium-DTPA, a marker for blood-brain barrier dysfunction, is significantly less in the primary progressive form, has led to the hypothesis that inflammation is less intense… (More)
