A 16-year-old girl developed left hemispheric deficits, which were followed by clouding of consciousness, quadriplegia, and subcortical blindness. Although we could not demonstrate a recent viral infection, the clinical features, laboratory and radiologic findings strongly suggested the diagnosis acute disseminated encephalitis. Cerebrospinal fluid abnormalities incompletely correlated with the clinical course. ...

The authors achieved the "in vivo" identification of the coeliac ganglia (C.G.), using computerised tomography (CT). This result was confirmed by autopsies and by CT scans of an anatomical specimen in which the coeliac ganglia had been previously marked. CT allows an exact location of the coeliac ganglia and can ...
Sugimoto T - - 1985
Computed tomographic (CT) scans were obtained from eight infants and young children with herpes simplex virus encephalitis. In two cases the initial scan showed diffuse edematous changes as a mass effect without laterality. Unilateral localized low attenuation in the initial scan was evident 4 days after the onset in one ...

Neurologic complications of gold are rare and include peripheral neuropathy, a Guillain-Barré-type syndrome, cranial nerve palsies and encephalopathy. Three cases of cranial neuropathy complicating chrysotherapy for rheumatoid arthritis are described. One also had a sensorimotor neuropathy associated with segmental demyelination and axonal degeneration, and another developed an encephalopathy which, on ...
Burton K - - 1984
We studied posthemiplegic hemidystonia in an adult, and generalized dystonia in two children. CT and magnetic resonance imaging (MRI) studies in the adult revealed infarction of the contralateral putamen and, to a much lesser extent, the head of the caudate nucleus. Both children had subacute encephalopathies (possible Leigh's disease), and ...
Gomez-Aranda F - - 1984
Neurological involvement in Q Fever is unusual. We present a case of encephalitis due to Coxiella Burnetii with neuroradiologic findings on CT not described previously, consisting in areas of decreased absorption coefficient in the subcortical white matter of both hemispheres, predominantly in the right. Differential diagnosis must be established from ...

The clinical data, histologic findings, and computed tomographic (CT) abnormalities in eight adult Haitians with toxoplasma encephalitis were analyzed retrospectively. Diagnosis was established by identification of Toxoplasma gondii on autopsy in five and brain biopsy in three specimens and subsequently confirmed by the immunoperoxidase method. All these patients, six of ...
Kuroiwa Y - - 1983
This report describes our experience with CT scanning in a patient with idiopathic familial basal ganglia calcifications. The clinical symptoms were characterized by late onset of progressive mental deterioration, seizures, involuntary movements and speech disorder. An extensive deep cerebral calcification was clearly visualized with CT as was midbrain and cerebellar ...
Procopis P G - - 1983
The clinical, pathological and laboratory findings of a 3-year-old boy with proven primary amoebic meningo-encephalitis are described. The EEG showed changes of acute cortical necrosis lateralised to one temporal lobe and was similar to that described with Herpes simplex encephalitis. CT scan findings indicated acute cortical inflammation and basal arachnoiditis. ...

Serial changes of cranial CT findings were studied in three siblings with Wilson disease during the course of D-penicillamine therapy. The older two cases with neurological presentation revealed low density areas in the region of the basal ganglia on the CT scans performed before treatment. Mild cortical atrophy and mild ...
Smits M G - - 1983
3 siblings with symmetrical calcifications in the strio-pallido-dentate system are described. Parathyroid function was normal and there were no signs of central or peripheral myelinopathy. This is the 9th family reported with autosomal recessive idiopathic strio-pallido-dentate calcinosis and the first to be investigated by computerized tomography (CT). CT scans appeared ...
Gilroy J - - 1982
In a case of paroxysmal kinesigenic choreoathetosis (PKC), an abnormality was found in the right hemisphere by computed tomography. It was not possible to define the pathological condition or the extent of the abnormality, and it is not known whether there was involvement of the basal ganglia. Nevertheless, this finding ...
Kim E E - - 1982
Four cases of basal ganglia infarction demonstrated by radionuclide brain imaging are presented. Bilateral basal ganglia infarctions in two patients were probably related to methanol intoxication and meningoencephalitis, and unilateral basal ganglia infarctions in two other patients were presumably due to cerebral atherosclerosis and/or hypertension. Various causes and mechanisms of ...

Calcification of the basal ganglia developed following intracranial hemorrhage in a neonate recovering from severe perinatal asphyxia. Cranial computed tomography is useful in demonstrating the anatomic distribution of dystrophic calcification in regions previously involved by hemorrhage. The demonstration of hemorrhage or hemorrhagic infarction with CT may help to verify the ...
Sawa G M - - 1981
The case history and CT scan of a patient with delayed encephalopathy following carbon monoxide intoxication are described. The patient recovered. The CT scan revealed symmetrical areas of decreased density at the level of the globus pallidus. This case differs in several ways from other cases of carbon monoxide intoxication ...
Vles J S - - 1981
In a retrospective study 2015 CT scans were studied for the presence of basal ganglia calcifications. These were discovered in 33 cases. No abnormalities in serum calcium or phosphate levels or any other specific clinical symptoms related to these calcifications were found. It is concluded that basal ganglia calcifications casually ...

A complex neurological syndrome, which rapidly appeared in a 54-year-old woman, created strong diagnostic difficulties. In fact, while the carotid-angiography was negative and CSF not significant, the scintigraphy suggested a multifocal metastatic or infarctual pathology. The CT scan easily allowed us to resolve the diagnostic problem, showing in the oval ...
Chi J G - - 1981
A 28-month-old Korean girl developed a rapidly progressive disease, characterized by disturbance of consciousness, tremor, nystagmus, ophthalmoplegia, irregular deep respiration and vomiting. The patient succumbed 2 weeks after the onset of the illness. CT scan disclosed bilaterally symmetrical, low density lesions in the white matter and lateral basal ganglia. Distinctive ...
Egger J - - 1981
The clinical and computed tomographic (CT) findings in 11 proven cases of mitochondrial cytopathy (mitochondrial myopathy, Kearns Sayre syndrome, ophthalmoplegia plus) were studied. The CT changes included focal low density lesions in the basal ganglia and white matter and atrophy which could be slight or diffuse and severe. Calcification has ...
Johnston H M - - 1980
A 7-year-old boy presented with deteriorating vision and macular degenerative changes. A month later he had developed unusual behaviour and increasing forgetfulness. An electroencephalogram showing periodic complexes, and high measles complement-fixation titres in the cerebrospinal fluid and blood, confirmed the diagnosis of subacute sclerosing panencephalitis. Four months after the onset ...
Sawada Y - - 1980
21 patients with acute carbon-monoxide poisoning had repeated brain scans by computerised tomography (CT) between May, 1977 and June, 1979. On the basis of the initial CT findings, the 21 patients could be divided into two distinct groups. In 11, areas of low density were seen bilaterally in the globus ...
Takahashi M - - 1980
Diagnosis of moyamoya disease primarily depends on the angiographic demonstration of stenosis and occlusion of the carotid bifurcation, and extensive parenchymal and leptomeningeal collaterals. According to previous reports, computed tomography (CT) reveals multiple low density areas in the brain, with atrophic changes. Based on this review of six cases, CT ...
Illum F - - 1980
Minor calcification of the basal ganglia was demonstrated by computed tomography in a woman, aged 66, who had survived carbon monoxide poisoning 48 years earlier. Extensive neuropathological investigations have demonstrated calcified lesions of the basal ganglia in a number of conditions, but their frequency and topographic distribution in vivo remain ...
Adams A E - - 1980
Intracranial calcifications are attributed to many diseases. The globus pallidus is almost always the site of bilateral idiopathic calcium deposits. Computed tomography is superior to conventional skull radiographs in detecting intracranial calcifications. Patients had symptoms that were often explained by other findings. Basal ganglia calcification alone is not a nosological ...
Zimmerman R D - - 1980
Herpes simplex is the most common cause of sporadic viral encephalitis. The recent development of specific antiviral chemotherapeutic agents offers new optimism for patients with this disorder if therapy is begun on or before the fifth day of the disease. Eight patients with herpes simplex encephalitis were studied by CT, ...
Go R T - - 1979
We have reviewed the medical records and radiographic examinations of 12 patients with herpes simplex encephalitis to assess the role of RN and CT in the early diagnosis of this disease. The initial RN study was positive in 83% (10/12) of cases while the initial CT study was positive in ...
Kaufman D M - - 1979
Eight patients with Herpes simplex encephalitis had computed cranial tomography (CT). In every case, areas of decreased attenuation were found in the temporal lobe(s); these areas extended to the insular cortex and often to the frontal or parietal lobes. This change developed between the third and the eleventh day of ...
Charney E B - - 1979
Although computerized tomographic (CT) findings are well recognized in numerous neurologic diseases of children, CT scan abnormalities of encephalitis have only been associated with herpes simplex infection. We describe two infants, one with coxsackievirus B2 meningoencephalitis and one with clinical encephalitis, whose CT scans were similarly abnormal during the acute ...
Ho S U - - 1979
Sequential computerized tomography (CT) was performed on a patient with seizures and an organic mental syndrome. Cerebral sarcoidosis was subsequently diagnosed on the basis of noncaseating granulomas in three organ systems. Cranial nerve palsies, hypothalamic dysfunction, and widespread disease were absent. An unusual neuroradiologic sequence of events indicated focal and ...
