Neuropathological study of the visual pathway from the retina to the occipital cortex in Creutzfeldt-Jakob disease (CJD) has been scarcely performed. In the present study, pathological involvement of the visual pathway was observed in a 54-year-old man with CJD. The patient had the onset of visual disturbances in December 1985. He subsequently developed progressive dementia, right hemiparesis, ataxia and dysarthria, and rapidly fell into decerebrate posture in February 1986. In March 1986, myoclonus appeared on the whole body and EEG revealed periodic synchronous discharges, while brain CT and CSF findings showed no abnormalities. Myoclonus was observed most frequently from May to October 1986, and then reduced gradually. Brain atrophy on CT started from April 1986, and was progressive till the end stage of the disease. He died in January 1988, and the total clinical course was about 24 months. Neuropathological examination revealed severe degeneration of the cerebral cortex and the white matter. In the cerebral cortex, marked loss of neurons, astrogliosis, and spongiform changes were observed. In the cerebral white matter, the destruction of myelin sheaths and axons were evident. The cerebellum showed prominent loss of granule cells. These findings are consistent with those of the panencephalopathic type of CJD. In the visual pathway, loss of ganglion cells and bipolar cells in the retina, mild demyelination of the optic nerve, neuronal loss in the lateral geniculate body, and severe degeneration in the visual cortex were observed. The present case suggests that the neuropathological investigation in the visual pathway from the retina to the occipital cortex is important for clarifying the pathological processes in the visual system in CJD.

Creutzfeldt-Jakob disease was diagnosed in four growth hormone recipients at the age of 10, 11, 18 and 19 years. To our knowledge, the two first cases are the first instances of Creutzfeldt-Jakob disease recorded in children. Three of them were still being treated with synthetic hormone at the onset of the disease. Neurological disorders: ataxia and diplopia, appeared first, dementia and myoclonus appeared later. Eighteen cases of Creutzfeldt-Jakob disease in growth hormone recipients are now recorded, and the present risk of Creutzfeldt-Jakob disease in pituitary growth recipients is estimated to be 1/300. Because of the long incubation period, new cases are to be feared. Other causes of iatrogenic Creutzfeldt-Jakob disease are reviewed. These facts incite to consider carefully using products of human origin in human therapy. The interactions between growth hormone, prion and host's genomic make-up are still not clear.

Serial brain CT and 123I-IMP SPECT were examined in a case with Creutzfeldt-Jakob disease (CJD). A 61-year-old woman had the onset of progressive dementia and gait disturbance in December 1988. Then, she developed left hemiparesis and dysarthria, and rapidly fell into akinetic mutism within about 2 months. Brain CT, MRI, and CSF findings showed no definite abnormalities. In February 1989, myoclonic movements appeared in several parts of the body and EEG revealed periodic synchronous discharges. Myoclonus was observed most frequently from March to May 1989, and then reduced gradually. She died in June 1990, and the total clinical course was 19 months. Brain atrophy on CT started from about 4 months after the onset, and progressed subacutely. At the end stage of the disease, diffuse brain atrophy including the cerebellum and the brain stem on CT was observed. SPECT revealed decreased perfusion in the cerebral cortex from 5 months after the onset to the end stage, but; perfusion in the cerebellum and the basal ganglia was relatively kept even at the end stage of the disease. The results suggest that SPECT is a useful examination for presumption of the pathological processes in CJD.

An autopsy case of ataxic form of Creutzfeldt-Jakob disease (Brownell and Oppenheimer, 1965) was reported. The patient, a 71-year-old male, noticed ataxic gait at the beginning of June in 1988, and was admitted to the Hiroshima City Hospital for the neurological examination at the end of June. He showed ataxia of the left arm and legs and diplopia. Gradually he became delirious at night. On July 16, tremor-like involuntary movement of the left hand was noticed. On July 20, he became somnolent and doubly incontinent. Myoclonus and paratonic rigidity were also observed. The EEG showed periodic synchronous discharge on July 25. The brain CT and MRI were normal. He became apallic gradually and died on October 28. The duration of illness was 5 months. At autopsy, brain weighed 1000gr. Cerebral atrophy and slight enlargement of the ventricles were observed. The cerebellum was also slightly atrophic. Histologically, the destruction of the cerebral cortical layer, slight sieve-like spongy state of the neuropil, slight neuronal loss of the thalamus and sieve-like spongy state of the striatum were observed. The cerebellar lesion was the most severe, where granular cell loss and gliosis of the cortex were observed.

The serial changes in computed tomography (CT) as correlated with the clinical and electroencephalographic findings were evaluated in 3 patients with Creutzfeldt-Jakob disease. The disease was subsequently confirmed histologically in 2. CT revealed that brain atrophy began in an early clinical stage and was prominent even before the state of akinetic mutism. Periodic synchronous discharges (PSDs) were observed either before or simultaneous with the observation of myoclonus. With progressive brain atrophy, the frequency of PSDs and the degree of myoclonus both decreased and disappeared 8 to 15 months after the onset of disease.

A 56-year-old woman initially noticed dizziness in October, 1988, and later dementia and gait disturbance developed, associated with myoclonus and periodic synchronous discharge in the electroencephalogram. On the basis of these clinical findings we made a diagnosis of Creutzfeldt-Jakob disease (CJD). Using RIA for ubiquitin (signal peptide of the ATP dependent proteolytic system), we measured the cerebrospinal fluid (CSF) ubiquitin levels. The CSF level of ubiquitin was markedly elevated in this case five months after the initial symptoms (230.0 ng/ml) compared with normal values (14.3 +/- 1.1 ng/ml) and values in patients with senile dementia of Alzheimer type (21.3 +/- 6.1 ng/ml) and vascular dementia (16.6 +/- 6.4 ng/ml). With progression of brain atrophy in this case, CSF levels of ubiquitin rapidly decreased to near the normal values. These findings suggest that CSF ubiquitin concentration reflects the activity of the disease process in CJD, and it may be useful in the diagnosis of CJD.

Creutzfeldt-Jakob disease (CJD) is presumably caused by a slow infectious pathogen or prion. The principal clinical features of Creutzfeldt-Jakob disease are dementia, pyramidal and extrapyramidal symptoms and signs, cerebellar dysfunction, and myoclonus. The patient rapidly deteriorates, declines to a vegetative state, becomes comatous, and is ultimately dead within several months. The authors present a case of Creutzfeldt-Jakob disease, proved by clinical findings, typical serial EEG, and pathologic features.

An 87-year-old male presented with rapidly progressive dementia, disorder of consciousness and myoclonus, suggesting Creutzfeldt-Jakob disease, but with nonspecific EEG and negative CT findings. Autopsy revealed a malignant angiotropic lymphoma with accumulation of tumor cells within small vessels of the brain and visceral organs. Immunohistochemistry disclosed a large cell lymphoma of B cell type.

We have encountered a case of Creutzfeldt-Jakob disease associated with myocarditis. A 77 year-old woman was admitted to a hospital with complaints of rapidly progressive visual disturbance, myoclonus and dementia. Electroencephalogram revealed a periodic synchronous discharge and Creutzfeldt-Jakob disease was suspected. Then she moved to our hospital, because acute myocarditis was combined with ST-T changes on electrocardiogram, and generalized hypokinetic motion of the left ventricle on echocardiogram. The abnormal findings in electrocardiography and echocardiography were transient. Blood levels of enzymes derived from the myocardium were slightly elevated. We could not find a distinct increase in the titer of neutralizing antibody to various viruses. In this case, the cause of myocarditis may have been associated with the infectious agent of Creutzfeldt-Jakob disease. This report might be the first one with a case of Creutzfeldt-Jakob disease complicated with myocarditis.
