Km. Weidenheim et Dw. Dickson, INTRANUCLEAR INCLUSION-BODIES IN AN ELDERLY DEMENTED WOMAN - A FORM OF INTRANUCLEAR INCLUSION-BODY DISEASE, Clinical neuropathology, 14(2), 1995, pp. 93-99
Intranuclear inclusion body disease (INIBD) is a rare neuropathologica
l entity characterized by eosinophilic intranuclear bodies in neurons
and/or glia. While this disease generally occurs in children, in whom
it presents as a multiple systems degeneration, a few adult cases are
also described. Only 4 previously reported adult cases have had an ass
ociated dementia and all of these patients had additional significant
neurological abnormalities. We report a 72-year-old woman with primary
degenerative dementia in whom intranuclear inclusion bodies (INIB) we
re a major neuropathologic finding. The IMB were most easily found in
astrocytes of Alzheimer II type, which had proliferated in the cortex
and white matter. Occasional neurons were affected. The inclusions con
sisted of 13 nm diameter filaments associated with amorphous electron-
dense material, arranged in a random pattern without lattice formation
. They did not stain with antibodies against all 3 neurofilament subun
its, glial fibrillary acidic protein, tau-l protein, vimentin, keratin
or actin. We conclude that INIBD is a rare substrate of primary degen
erative dementia in elderly patients.
