Radiographic quality as well as adverse effects of intrathecal metrizamide instillation was prospectively investigated in thirty-three clinical cases admitted to the department of neurosurgery, University of Tokyo Hospital, and Kantoh Teishin Hospital. Metrizamide CT cisternography was performed in fifteen cases using in most cases 10 ml of 170 mg I/ml solution through lumbar route. Eleven cases exhibited "normal" pattern CSF circulation and the remaining four, "delayed" pattern. Eight cases (53%) experienced headache, nausea, and/or vomiting several hours after the instillation. All of these belong to the "normal" pattern group. Four cases of "normal" pattern received electroencephalographic examinations before and after metrizamide instillation. Three revealed appearance of negative spike and slow wave burst or sharp waves one to twenty-four hours after the instillation, along with penetration of metrizamide into brain parenchyma. Diagnostic quality was interpreted as "good" in eleven cases. Small acoustic neurinoma, pituitary adenoma, arachnoid cyst, and subdural hygroma were diagnosed among others. Metrizamide ventriculography was done in four cases. No untoward effect of significance was attributed to metrizamide per se. Cervical myelograpy and/or CT myelography was done in fourteen cases using, in most cases, 10 ml of metrizamide 170 mgI/ml. Polytome tomography with metrizamide instillation through lateral cervical puncture was highly diagnostic, whereas, ordinary X-ray with lumbar instillation yielded less satisfactory results. CT myelography in cases of subarachnoid block required good consideration on instillation site and positioning of the patient. Six cases (50%) among twelve cases where metrizamide had run into the cranial cavity experienced headache, nausea, and/or vomiting to a lesser degree than those of cisterno graphy. Metrizamide is the first contrast agent ever made which can be safely introduced into human subarachnoid space, if administered judiciously, nervous. However, metrizamide is weakly toxic to central system and provokes minor untoward effects as well as electroencephalographic abnormalities and, sometimes, clinical convulsive seizure. It would be wiser to restrict the dosage of metrizamide in cisternographic study, expecially in cases of "normal" pattern CSF circulation, to 1.2 gI or 7 ml of 170 mg I/ml solution. Routine use of X-ray cisternography should thus be discouraged because it needs higher concentration of metrizamide in the intracranial cisterns.

Two hundred and eighty elderly patients who were referred because of a principal problem of confusion were investigated by computerized tomography; 94% were suffering from a 'dementia syndrome' and unrecognized receptive dysphasia was the commonest problem in the remainder. One hundred and twenty-four patients were suffering from senile dementia of the Alzheimer type, and 79 from multi-infarct dementia. Space-occupying lesions (tumour, subdural haematoma or hygroma) were found in 32 (11%). Of the 25 with other intracranial and extracranial causes, 64% had potentially treatable lesions (PTL). In only four cases was no diagnosis made. PTL were found in 31% of 170 patients with a duration of confusion of less than a year compared with 1% of 110 patients with a longer duration. In 48 of the former group, confusion was an isolated phenomenon; 12 of these (25%) had a PTL, as had 27 of 88 with confusion and a focal neurological deficit (31%). All five patients with recognized seizures, and six of 15 of those with reduced alertness had PTL. Twenty of 37 patients with neurosurgical lesions underwent surgery.

The CT findings in 120 cerebral palsied children are analysed. The 72.5% positive findings are correlated with the clinical types, as well as the aetiological basis for the cerebral palsy. The spastic type, 83.3% of the total number of children, had the highest positive findings. The yield was increased in children with seizures (91.3%) and those in the postnatal group (90%), as well as those with birth trauma and neonatal asphyxia (94%). The findings were those of atrophy in 30.8%, hydrocephalus, in 10%, infarct in 11.6%, porencephaly in 8.3% and others. The atropic changes and their patterns are explained. Treatable lesions, such as tumour, hydrocephalus, subdural haematoma, porencephaly and hygroma were identified in 22.5% of cases. It is concluded that CT scan is definitely efficacious in the management of cerebral palsied children.

The difficulties of early diagnosis of Menkes' kinky hair syndrome are described guided by the clinical courses of three related patients. One of these children could be observed continuously from birth. Different from other descriptions the diagnostic value of the clinical features observed in our patients is estimated as follows: 1. severe cerebral degeneration with seizures in the first year of life; 2. subdural hygroma; 3. decreased levels of serum copper and serum coeruloplasmin; 4. hair abnormalities; 5. skin abnormalities. The diagnosis is likely, if serum copper and serum coeruloplasmin are decreased. The diagnosis is proved by increased copper uptake into cultured fibroblasts. The prenatal diagnosis is possible by chorionic villus biopsy or amniocentesis. The importance of carrier detection by cultured fibroblasts and subsequent genetic counselling is underlined.

A patient with subdural hygroma in the perinatal period developed into a right hand sided spastic hemiplegia with epileptic seizures and intellectual deficit. On the age of 17 years a linear dermatosis that proved to be a naevus unislateris was remarked. The combination of linear nevi and neurological deficit is known as the epidermal nevus syndrome.

Leptomeningeal cyst as a rare complication of skull fracture in children is well documented. Most cases occur months or years after the original skull fracture, with characteristic roentgenogram findings. The authors report two cases of leptomeningeal cysts in children less than two years old. The association of hygroma, severe brain injury, increased ICP, and early development of leptomeningeal cyst are discussed. Both patients sustained parietal diastatic skull fracture and developed external brain herniation within 10 days after motor vehicle accidents. Clinically they presented with seizure, hemiparesis, and an enlarging subgaleal mass over the skull fracture. MRI demonstrated severe underlying brain contusion, hygroma around the fracture site, and brain herniation through the skull fracture. Surgical repair of dural laceration and cranioplasty produced good results. The development of hygroma and increased intracranial pressure might account for the early development of leptomeningeal cysts in these two cases.

An infantile head injury has unique features in that infants are totally helpless and dependent on their parents, and biomechanical characteristics of the skull and brain are very different from those of other age groups. The authors reviewed a total of 16 infant head injury patients under 12 months of age who were treated in our hospital from 1989 to 1997. Birth head injury was excluded. The most common age group was 3-5 months. Early seizures were noted in 7 cases, and motor weakness in 6. Three patients with acute intracranial hematoma and another 3 with depressed skull fracture were operated on soon after admission. Chronic subdural hematomas (SDHs) developed in 3 infants. Initial CT scans showed a small amount of SDH that needed no emergency operation. Resolution of the acute SDH and development of subdural hygroma appeared on follow-up CT scans within 2 weeks of injury. Two of these infants developed early seizures. Chronic SDH was diagnosed on the 68th and 111th days after the injuries were sustained, respectively. The third patient was the subject of close follow-up with special attention to the evolution of chronic SDH in view of our experience in the previous 2 cases, and was found to have developed chronic SDH on the 90th day after injury. All chronic SDH patients were successively treated by subduro-peritoneal shunting. In conclusion, the evolution of chronic SDH from acute SDH is relatively common following infantile head injury. Infants with head injuries, especially if they are associated with acute SDH and early development of subdural hygroma, should be carefully followed up with special attention to the possible development of chronic SDH

During the period from 1983 to 1999, 12 patients with symptomatic arachnoid cyst were treated. The mean patient age was 20.6 years. The most common location was the middle fossa (10 cases). Initial CT scan revealed associated subdural hygroma in 7 patients and hydrocephalus in one. Clinical symptoms were related to increased intracranial pressure, cranio-megaly and seizure. One infant with a huge arachnoid cyst was treated, using a cystoperitoneal (CP) shunt. Four patients underwent membraectomy. Combination CP shunt and membraectomy was performed in 5 patients. The remaining 2 arachnoid cysts were complicated with subdural hygroma and, initially, they were observed conservatively, but hygroma gradually changed to hematoma. One was treated by irrigation and the other hematoma was spontaneously absorbed. Significant complications included extensive subdural effusion in one patient, contralateral chronic subdural hematoma in two, intracranial hypotension in two, and shunt dependency in one. There were no recurrences during the follow-up period (mean 3.6 years).

The purpose of this study was to assess the effect of epilepsy surgery on seizure outcome in children and adolescents under 18 years with intractable epilepsy due to focal cortical dysplasia. We analysed clinical data, such as age at seizure onset, epilepsy course, localisation of focus from presurgical evaluation, MRI, tissue pathology and seizure outcome in 68 patients 6 months to 9 years after epilepsy surgery. Seizure outcome was classified according to the Engel classification. Mean age at seizure onset was 7 months, ranging from the first days of life to 7 years. All patients had medically intractable epilepsy. Localisation of the lesion was predominantly extratemporal: posterior (uni- or multilobar) 43 %, frontal without central region 26 %, multilobar involving central area 19 % and temporal in 12 %. MRI signs typically seen in cortical dysplasia (FCD) such as localised blurring of gray-white matter junction was found in 68 %, dysgyria in 62 %, thickening of the cortical ribbon in 46 % and T2 signal elongation of the subcortical white matter in 40 % of the patients' MRI. Age at surgery ranged from 5 months to 16 years; 14 patients were under 2 years when operated on. In 34 patients (6 patients under 3 years) subdural grid electrode evaluation was performed prior to surgery. Pathology revealed focal cortical dysplasia without balloon cells (type I) in 60 %, FCD of the balloon cell subtype (type II) in 40 % of the specimens. Postoperative complications were subdural hygroma in 5 and an increased motor deficit in 2 patients. Up to two years after epilepsy surgery 50 % of the children were seizure free (Engel class I), 10 % Engel class II, 33 % Engel class III and 7 % unchanged (Engel class IV). Long-term seizure outcome (> 3 years post surgery) in 32 patients showed similar results (class I 50 %, class II 19 %, class III 28 %, class IV 3 %). Complete resection of the dysplastic lesion was significantly correlated with favorable seizure outcome, whereas seizure outcome was not significantly different in patients with mild (type I) or balloon cell (type II) FCD. Children operated after 6 years of age had no better outcome than children operated in infancy or at preschool age. Epilepsy surgery resulted in good (class I and II) seizure control in 60 % of children with intractable epilepsy due to focal cortical dysplasia.

Parry-Romberg syndrome (PRS) is a poorly understood disorder characterized by progressive hemifacial atrophy. A number of neurologic associations have been reported. We describe a rare association of seizures, PRS, and subdural hygroma. To the best of our knowledge, this association has not been reported in the literature.
