Cervical spinal cord MRI was unremarkable except for mild spinal canal stenosis. She was diagnosed as having atypical Alzheimer's disease. During the next six months her general condition deteriorated further with decubitus ulcers and pneumonia. At the age of 65, she died of empyema. The mI 1 general necropsy showed empyema, multiple erosion of the gastric mucosa, atrophy of the pancreas, small stones in the bladder, myoma v bo uteri, and an adenoma in the thyroid. Gross neuropathology The weight of the unfixed brain was 1030 g. The brain showed no abnormalities exter- nally. Coronal sections of the cerebrum, cere- bellum, and brainstem were unremarkable.

Microscopic neuropathology Numerous senile plaques and neurofibrillary Jd; tangles were found in the whole cortical grey x.0 matter, caudate nucleus, putamen, hippo- campus, parahippocampus, and amygdala on methenamine-Bodian stain (fig 3).

Numerous neuropil i,.~ 4vN 8i threads, diffuse plaques, ghost tangles, and amyloid angiopathy were also seen in the cere- brum. Some senile plaques contained degen- ,§ erative neurites. There was no definite spongy j change except patchy microspongiosis in the ;*! * isi; insula and motor cortex. In the thalamus, there were neither senile plaques nor neuro- fibrillary tangles. Severe astrocytic gliosis and neuronal loss had occurred in the medial part of the bilateral thalamus, especially the medial http://jnnp.bmj.com/ nucleus (fig 4).
