Two cases of spontaneous cerebral ventriculostium are presented. The first case is that of a 3 year-old girl with a thumb-sized soft scalp tumor of the occipital region (dural hypertrophy) and hydroencephalodysplasia (Picaza). PVG revealed noncommunicating hydrocephalus with asymmetrical deformity of the lateral ventricle and agenesis of corpus callosum (Fig. 1). Ventriculoatrial shunt was performed. Three years passed under the useful life when she readmitted to our clinic complaining headache, nausea and vomiting. On the first hospital day she fell into respiratory arrest accompanied with coma after the tonic convulsion, and eventually, she died on the fourth hospital day. Postmortem examination revealed spontaneous cerebral ventriculostium which communicated with the posteromedial trigone of the left lateral ventricle (Fig. 3). Combined other malformations such as dysgenesis of the corpus callosum and only one anterior cerebral artery, etc. were found. The second case is that of a young adult, a 22 year-old male with rapidly progressing intracranial hypertension. PVG revealed marked dilatation of the lateral and the third ventricle, non-filling of the aqueduct and spontaneous cerebral ventriculostium which communicated with the posterior part of the third ventricle (Fig. 4). And insidiously he fell into akinetic mutism. After suboccipital exploratory craniotomy and ventriculo-peritoneal shunt akinetic mutism improved gradually, and he was discharged on foot after 7 months. PEG performed on June 8, 1973, showed no evidence of aqueduct obstruction and injected air passed from the fourth ventricle to the third one smoothly. He lives on now under a useful condition. These 2 cases are the first report on literatures in Japan, but presumably there must be many other cases. Since W. H. Sweet reported his own two cases of spontaneous cerebral ventriculostium on 1940, more than thirty cases have been published on literatures. However, there are found various expressions to describe the same condition (Table 1). We would like to propose that the most suitable expression is "ventriculostium" not only in deference to the originality of W. H. Sweet but also not to confuse this pathogenetic state with other similar conditions. The author's next interest is the chronological fact that from W. H. Sweet (1940) to A. Torkildsen (1948), all but one ostiums reported situated at the posteromedial trigone of the lateral ventricle, whereas after A. Torkildsen, they were found at the posterior part of the third ventricle in many cases. The reason is unknown. It would appear that three main conditions are necessary for the development of ventricluostium just beneath the tentorium. The first, there must be increased pressure within the lateral or the third ventricle. The second essential feature is the lack of any large space occupying lesion in the the infratentorial space. The third, there must be wider space between the tentorial incisura and the brain stem.

Mumps virus is one of the most common causes of viral meningitis. Although brain involvement has been observed in a low proportion of children with mumps meningitis, a pure form of mumps encephalitis is extremely uncommon in the adult. A 23 year-old man presented with a rapidly evolving syndrome of cephalalgia , vomiting, mutism, disorders of gait, somnolence and dystonic movements. The electroencephalogram showed a diffusely slowed background activity. The CSF contained no cells, but the total protein concentration was elevated. The patient recovered without sequelae, but severe intellectual and motor disturbances persisted during more than a month. Serological studies showed an increase of blood IgM mumps-specific antibodies. We conclude that mumps encephalitis, although infrequent, should be considered among viral diseases that mimic herpes simplex encephalitis in the adulthood.

We studied five patients with cerebral hemorrhage limited to the head of the caudate nucleus. This rare localization represents 11% of central nuclei hemorrhages. This entity has various clinical expressions; some are similar to a subarachnoid hemorrhage, others show the same manifestations associated with hemiparesis and neuropsychological findings, while still in others, the neuropsychological syndrome with speech, behaviour or memory disturbances predominates. Recovery depends on the patient's previous clinical status and on the presence of associated lesions at the time of hemorrhage. Typical warning signs, like headache, are often absent in the elderly and debilitated. Meningismus is explained by the intraventricular extension of the hemorrhage. Motor deficit, usually moderate, is probably due to impairment of the anterior portion of the posterior arm of the internal capsule. Destruction of the head of the left caudate nucleus, which is part of the circuit causing "subcortical aphasias", is responsible for non specific speech disturbances, that are however remarkably rich in semantic paraphasias. These dysfunctions could be caused by a "cortical diaschisis" as suggested by SPECT analysis. Memory dysfunction as a result of caudate lesion is questioned. However confusion and behavioural disturbances, like preservations, transitory mutism and self neglect, seem characteristic. As shown by cerebral blood flow (CBF) studies, these disturbances might represent a frontal dysfunction caused by the interruption of the dorso-latero-prefrontal and orbito-frontal circuits. When the hemorrhage extends beyond the head of the caudate nucleus, behavioural changes occur due to the involvement of neighbouring structures such as the thalamus, internal capsule, temporal lobe and nucleus accumbens. Caudate hemorrhages occur mostly in the elderly, often with long-standing arterial hypertension causing lesions of the lenticulo-striate arteries. Severe stenosis or complete occlusion of the middle cerebral artery with a fragile anastomotic circuit or angiopathies in younger individuals (particularly Asiatics: moyamoya disease) are less frequent, but they should be considered and investigated by arteriography. Vascular malformations are a rare cause and a relationship with amyloid angiopathy can only be suspected.

The clinical features, investigative profiles and outcome of 46 patients with biopsy or autopsy-proven herpes simplex encephalitis admitted to the Institute of Neurological Sciences, Glasgow between 1962 and 1985 were analysed retrospectively. The protean presenting symptoms and signs included a history of a prodromal influenza-like illness (48 per cent), rapid onset of headache, clouding of consciousness and confusion (52 per cent), meningism (65 per cent), raised intracranial pressure (33 per cent), deep coma (35 per cent), mutism or aphasia (46 per cent), focal neurological signs (89 per cent), and seizures (61 per cent). When seizures occurred they were almost always focal. The electroencephalogram was the most useful diagnostic test being abnormal in all cases, the majority showing focal changes in one or other hemisphere. Of the neuroradiological procedures employed, computerized tomographic and isotope brain scanning most frequently demonstrated localizing abnormalities in one or both temporal and/or frontal lobes. Midline shift was seen in half the cases. The cerebrospinal fluid was abnormal in every case but was not diagnostic. Cerebral biopsy of one temporal lobe was performed in 40 cases and a positive diagnosis of acute necrotizing encephalitis was made in 37 of these. Herpes simplex virus was isolated from the brains of 29 of the 40 cases in which the procedure was attempted, but immunofluorescence assays for antigens to herpes simplex virus were only positive in 11 out of 25 cases. Serological assays showed a greater than four-fold rise in the anti-herpes simplex virus antibody titre in 13 out of 22 patients tested.(ABSTRACT TRUNCATED AT 250 WORDS)

A 59-year-old man was admitted because of frequent vomiting and obtundation in February 1982. Neurological examination on admission revealed only slight impairment of consciousness. Papilledema, meningeal irritation sign and paralysis were not elicited. The plain CT scan was normal, but the CT scan with contrast material showed patchy enhancement in the left temporal lobe and around the third ventricle. Cerebral angiography showed a dural arteriovenous malformation (dural AVM) in the left transverse sinus fed by the left occipital artery, and the retrograde flow into the straight sinus. By the third day following admission, the level of consciousness became alert. The patient did not complain of headache, bruit and visual disturbance. He showed mild disorientation and memory disturbance. But his ordinary daily-living was independent. In August 1982, the patient gradually became inactive and apathetic. At times he lay in bed with moving his eyes, swallowing foods. At other times, he lay in bed with closing his eyes, immobile, and unresponsive except to strong painful stimuli. The patient was incontinent and required nursing care. During three month periods, the patient progressively became somnolent, speechless and immobile. Eventually, he was in a state of akinetic mutism. The patient became unresponsive. The state of consciousness fluctuated within a narrow range. The pupils were isocoric and did not react to light. He sometimes moved his eyes horizontally, but the vertical eye movement was limited. Deep tendon reflexes were hyperactive with Babinski reflex bilaterally. Passive mobilization of extremities revealed hypertonic. The CT scan disclosed the bilateral symmetrical infarction of the thalamus.(ABSTRACT TRUNCATED AT 250 WORDS)

We report a 57-year-old woman with progressive gait disturbance, headache, character change, convulsion and coma. She was well until 55 years of age, when she noted an onset of unsteady gait. At times she experienced transient weakness in her right hand, which was followed some difficulty in articulation. She was admitted to our service for the work up on April 6, 1992. Neurologic examination at that time revealed an alert Japanese lady in no acute distress. She was oriented to all spheres, however, she was somewhat bradyphrenic and had some disturbance in recent memory. Higher cerebral functions appeared intact. The visual acuity and visual fields were normal as were the optic fundi. Pupils were round and isocoric reacting promptly to light. Ocular movement was full, however, horizontal nystagmus was noted upon right lateral gaze. The sensation of the face was intact. She showed right facial paresis of the central type. Hearing was intact. She showed slurred speech and some difficulty in swallowing. The tongue was deviated to the right. Her gait was wide based and unsteady; tandem gait was difficult, however, walking on toes and on heels were performed well. No cerebellar ataxia was noted, but she showed some clumsiness in her right hand. Deep reflexes were symmetric and normally reactive; plantar response was extensor bilaterally. Sensation was intact; no meningeal sign was elicited. Routine laboratory work up was unremarkable; the CSF was under a borderline pressure (180 mmH2O) and contained 39 mg/dl of protein and 59 mg/dl of sugar. Cranial CT scan revealed diffuse low density areas involving bilateral cerebral white matter as well as the brain stem; MRI revealed high signal intensity lesions in those areas; gadolinium enhancement was negative; cortical sulci were effaced and the anterior part of the left lateral ventricle was compressed without deviation of the midline structure. The patient was treated with steroid pulse therapy without effect. She was discharged for out patient follow up, however, she developed a convulsion which was followed by loss of consciousness, and was admitted again to our service. She had never gained consciousness after this episode, and remained in the state of akinetic mutism. Follow-up CT and MRI did not show much change, although the area of high signal density lesions slightly enlarged on June 1, 1993. Her clinical course was complicated by drug induced bone marrow suppression and nephrotic syndrome. She expired on September 8, 1993 after developing sudden drop of blood pressure and bradycardia.(ABSTRACT TRUNCATED AT 400 WORDS)

We have observed an unusual low amplitude, slow and featureless electroencephalogram (EEG) pattern in some human immunodeficiency virus (HIV) infected patients without focal lesions on computerized tomography (CT scan) of the head. Out of 17 cases, 13 with AIDS and 4 with HIV positive status, 6 had low amplitude EEGs with slowing, all in the AIDS group. Nine of the 13 AIDS patients were demented, and 4 of these demented patients had slow verbal responses and mutism, indicating advanced HIV-related dementia. All 4 had low amplitude, slow EEGs. The patients with low amplitude, slow EEGs also had atrophy on CT scan by visual assessment and by measurement of ventricular indices. Of 17 age-matched controls referred for non-specific complaints such as headache and dizziness or for psychiatric disorders, 3 had EEGs read as low amplitude with slowing; two had normal mental status and one was psychotic. Although this EEG pattern is not etiologically specific, it may correlate with advanced dementia and atrophy on CT scan in AIDS patients.

We report 3 patients, ages 5, 9 and 13 years, with mutism following posterior fossa surgery (PFS). All presented with headache of 10-180 days duration, excellent premorbid learning performance and paucity of neurologic signs. Radiographic studies demonstrated large posterior fossa tumor occupying the fourth ventricle, and hydrocephalus, leading to gross total resection of the tumor. Within 24-48 hr, all patients were mute. None had problems with swallowing and coughing. All were able to nod "yes or no," follow commands, point to body parts, and make their wants known by gestures. Jaw, gag, snout and palmomental reflexes were normal. CT scan and MRI Brain showed no cerebral hemispheric lesions. All children regained speech although dysarthric, within 5-12 weeks. Twenty-two previously reported cases are similar to ours. We conclude that this post-surgical mutism syndrome is unique and must be differentiated from aphemia, Broca's aphasia, hysterical mutism and elective mutism. The cerebellum, in a way not yet understood, does play a role in speech production.

We report a case of Creutzfeldt-Jakob disease in a 38-year-old man, transmitted by a cadaveric dural graft. In August 1985, he underwent cranial nerve decompression for hemifacial spasm and received a cadaveric dural graft for dural closure. He had been well until he began to complain of blurred vision and headache in May, 1990. He developed dementia, myoclonus and urinary incontinence over the subsequent 3 months. He was admitted to our hospital in August, 1990. On admission, he was somnolent and showed gait disturbance, myoclonus in extremities and elevated deep tendon reflexes symmetrically. The results of analysis of blood, urinary and cerebrospinal fluid were normal. The initial computed tomography (CT) and magnetic resonance imaging detected no abnormality. Electroencephalography showed typical periodic synchronous discharge (PSD). There was progressive worsening of his neurological symptoms, and this developed into mutism in September, 1990. CT, 11 months after clinical onset, showed marked enlargement of the ventricles and the sulci. In view of his rapid worsening clinical course, PSD findings on electroencephalography, and delayed progressive changes of CT findings, the diagnosis of CJD disease was made. The cadaveric dural graft was suspected as the cause of the patient's condition. Since Thadani et al reported the first case of CJD transmitted by cadaveric dural graft in 1988, 3 other cases have been reported. This is most likely the 5th reported case of Creutzfeldt-Jakob disease transmitted by cadaveric dural graft.

Bacillary dysentery, an acute infection caused by various strains of Shigella, is characterized by abdominal pain, tenesmus, and diarrhea with mucus, pus and blood. Neurologic manifestations including meningismus, delirium and convulsions may accompany the infection. We describe a thirteen-year-old girl who presented with headache, convulsion and loss of consciousness at the onset and developed diarrhea with blood and pus after hospitalization. The diagnosis of shigellosis was based on clinical data and isolation of the microorganism in the stool specimen. After improved physical functions, the patient developed mutism that continued for two days in the course of her illness, despite having no history of neurologic or psychological problems. She was diagnosed by a psychiatrist with organic mental syndrome NOS (Not Otherwise Specified) according to DSM-III-R criteria. None of the conditions that may cause mutism could be confirmed. This is the first reported case of mutism accompanying shigellosis.
