Several clinical trials have demonstrated that cisplatin-based chemotherapy for primary intracranial germ-cell tumors is effective as a neoadjuvant chemotherapy. In this report, we describe a 6-year-old boy, Down syndrome and Hirschsprung's disease with intracranial pure yolk sac tumor treated by combined chemotherapy with cisplatin, vinblastine, bleomycin and cyclophosphamide (modified VAB-6 regimen). He had been admitted to our hospital because of intractable vomiting, and left facial nerve palsy since 1 month before. An MRI revealed an enlarged mass, 4cm in diameter, in the left cerebello-pontine angle with uniformal enhancement by Gd-DTPA, and bilateral ventricular dilatation. He was found to have increased serum alpha-fetoprotein level (AFP 11, 786ng/ml), but not human chorionic gonadotropin beta-subunit. After a partial resection of the tumor, diagnosed as pure yolk sac tumor, and ventriculo-peritoneal shunt, three courses of combined chemotherapy with cisplatin, bleomycin, vinblastine and cyclophosphamide (modified VAB-6 therapy) were carried out. The serum AFP level returned to normal, and the tumor mass entirely disappeared (a complete response) on MRI after the second course of chemotherapy. However, cisplatin-induced vomiting and mild neutropenia and renal tubular injury developed after the third course of chemotherapy. Irrespective of administration of recombinant human G-CSF and broad spectrum antibiotics, he suffered from pneumonia and died of septic shock and multiple organ failure. Autopsy showed microscopic residual tumors. The combination chemotherapy with cisplatin, bleomycin, vinblastine and cyclophosphamide is effective for initial treatment of childhood intracranial yolk sac tumor. It is necessary, however, to reevaluate the cisplatin dosage and treatment schedule in order to reduce such side effects as bone marrow suppression and renal damage.

The clinicopathological features of a previously unrecognised type of acute encephalopathy prevalent among Japanese children is described by reviewing the records of 13 consecutive patients treated and 28 previously reported cases. The hallmark of this encephalopathy, proposed to be a novel entity termed acute necrotising encephalopathy of childhood, is multiple, necrotic brain lesions showing a symmetric distribution. The encephalopathy was noted in previously healthy children after respiratory tract infections, with presenting symptoms of coma, convulsions, vomiting, hyperpyrexia, and hepatomegaly. Laboratory examinations disclosed liver dysfunction, uraemia, and hypoproteinaemia. The histological appearance of the liver was variable and non-specific. Cerebrospinal fluid contained an increased amount of protein. Computed tomography and MRI showed the presence of symmetrically distributed brain lesions of the thalamus, cerebral white matter, brainstem, and cerebellum. Necropsy examination confirmed extensive fresh necrosis of these regions with evidence of local breakdown of the blood-brain barrier. Based on the characteristic combination of clinical and pathological findings, acute necrotising encephalopathy of childhood can be distinguished from previously known encephalopathies, including Reye's syndrome.

This study included 125 cases of cerebellar infarction followed during an average period of 4.3 years. The diagnosis was made by CT or MRI. Infarctions localized to the territory of the superior cerebellar artery (SCA) and the territory of the posterior inferior cerebellar artery (PICA) occurred with the same frequency. Transient ischemic attacks preceded infarction in 26% of cases. Symptoms and signs were usual with sudden association of headache, dizziness, unsteadiness and vomiting. Vestibular signs were more important in infarctions of the PICA territory; cerebellar signs and dysarthria were more frequent in infarction of the SCA territory. A decreased level of consciousness developed in only 21% of cases. Surgical operation was required in 9 cases. Investigations have showed the large responsibility of cardiac embolisms and atherosclerosis. Short term outcome was more often favourable: 116 patients were alive at the end of the first month; 80% of survivors were independent one year later. At 5 years, 73% of patients were alive. After the acute period, mortality was mainly due to cerebro-vascular and cardiac events.

We describe herein the clinical symptoms, clinical course and results of investigation of 7 patients with bilateral basal ganglia-thalamic lesions (BBTL). All patients had spastic quadriplegia with rigidity. They were unable to sit and turn over. They could follow objects, turn head towards a sound and recognize parents to some degree. They were all evaluated as having the most severe degree of disability (Oshima's classification 1). They all had dysphagia and 2 patients had a episode of bradycardia and hypothermia, which might be evidences of brain stem disorders. Muscle hypertonia, vomiting, hematemesis and obstructive respiration, which were the major complications for the patients, worsened with age. High percentage of histories of birth asphyxia and poor feeding in the neonatal period suggested that perinatal brain insults might be one of the important factors for developing BBTL. It seemed to be difficult to explain that such diffuse brain injuries in our cases were caused by only the insults during parturition. Brain insults during parturition as well as prenatal factors probably participate in developing BBTL. Although the cerebrum of the patients seem to be relatively preserved in the images of head CT-scan, MRI of the patients revealed diffuse brain lesions. All of five patients tested had an abnormal auditory brain stem response (ABR). These investigations demonstrated that patients with BBTL have diffuse brain damage including brain stem. Further observation is needed to verify the mechanisms of development and the time of onset of BBTL.

Cerebellar infarcts have been neglected for a long time and are now shown well by CT and especially MRI. Some infarcts involve the full territory supplied by a cerebellar artery. They are frequently complicated by edema with brain stem compression and supratentorial hydrocephalus, requiring at times emergency surgery, and are often accompanied by other medullary, medial pontine, mesencephalic, thalamic and occipital infarcts. On the other hand, partial territory infarcts are usually confined to the cerebellum and have a benign outcome with total recovery or minimal disability. They are more common than full territory infarcts. However, clinical presentations are similar to those full territory infarcts, differing mainly by the lack of drowsiness or unconsciousness. The main symptoms are vertigo, headache, vomiting, unsteadiness of gait and dysarthria. Signs include ipsilateral limb dysmetria, ipsilateral axial lateropulsion, ataxia and dysarthria. Vertigo is more severe and rotary in posterior inferior cerebellar artery territory infarcts, whereas dysarthria and ataxia are prominent in superior cerebellar artery territory infarcts. A few brain stem signs are sometimes added. In these territorial cerebellar infarcts, cardioembolism is the most common cause. Atherosclerotic occlusion comes next, involving the intracranial part of the vertebral artery and, less frequently, the lower basilar artery, both locations inaccessible to surgery. Other causes are artery to artery embolism from a vertebral artery origin stenosis, or the aortic arch, in situ intracranial branch atherosclerotic occlusion, and vertebral artery dissection. Border zone cerebellar infarcts occur in one third of the cases. They are small cortical or deep infarcts. They have the same symptoms and signs as territorial infarcts except for more frequent postural symptoms occurring over days, weeks or months after the ischemic event. The infarcts mainly have a thromboembolic mechanism, and sometimes have a hemodynamic mechanism: 1) focal cerebellar hypoperfusion due to large artery occlusive disease in more than half the cases, 2) small or end (pial) artery disease due to hypercoagulable state (thrombocythemia, polycythemia, hypereosinophilia, disseminated intravascular coagulation), arteritis or intracranial atheroma, and 3) rarely systemic hypotension due to cardiac arrest.

A case of a large empty sella was reported, which was intrasellar herniation of the third ventricle associated with a prolactinoma. The patient was a 46-year-old female admitted due to consciousness disturbance with pyrexia and vomiting. She had amenorrhea, galactorrhea and sterility in her past history. On admission, physical and neurological examinations revealed severe dehydration, systemic edema, systemic hypotension, nuchal rigidity, papilloedema and goiter. A spinal tap was performed and revealed an increase in CSF pressure. Laboratory data indicated CSF lymphocytosis, an increase in CSF protein content, high titers of serum microsome test, a low concentration of anterior pituitary hormones in serum except for PRL, and an unusually high concentration of PRL in serum and CSF (4680 and 222ng/ml, respectively). Plain films of the skull showed destructive enlargement of the sella turcica. The patient was diagnosed as having non-bacterial meningitis, chronic thyroiditis and a prolactinoma with hypopituitarism and was then admitted to our department. Except for amenorrhea she was asymptomatic under the administration of levothyroxine, hydrocortisone and bromocriptine. CT scan, MRI, pneumoencephalography and CT cisternography as further examinations disclosed the intrasellar herniation of cisterns and the third ventricle, which were surrounded by an intrasellar parenchymal layer. This layer was thought to be still viable prolactinoma tissue. We supposed the third ventricle entered the enlarged sellar cavity following the spontaneous degeneration of the large prolactinoma. Although we could find some documented reports of similar cases, the complete herniation of the third ventricle secondary to degeneration of an adenoma might be rare.(ABSTRACT TRUNCATED AT 250 WORDS)

Nine cases of symptomatic Rathke's cleft cyst are reported. Their most frequent signs and symptoms included headache, chiasmal syndrome and hypopituitarism, while one of the cases developed a sudden onset of headache and vomiting following diabetes insipidus. Endocrinological findings showed a decreased ACTH, gonadotropin and growth hormone more frequently while there were 2 cases of hyperprolactinemia and 1 case of diabetes insipidus. In a neuroradiological examination, a plain skull X-ray showed 5 cases of ballooning of the sella turcica, and a CT scan demonstrated a low to high density of the cyst and 2 cases of marginal enhancement of the cyst. MRI mostly demonstrated a well delineated mass at the sella extending mostly into the suprasellar region and a low to high intensity of the cyst in the T1-weighted image. Two cases were marginally enhanced after gadolinium DTPA administration. The pathological examination, done on 6 cases, showed either single or multiple layers of the epithelium which were mostly ciliated. The epithelium was positive in PAS and Alcian blue in all cases and a histochemical examination showed 3 cases to be positive in EMA and 2 cases positive in CEA. A resection of the cyst wall and an opening of the cyst is thus recommended in symptomatic cases. Therefore, the transsphenoidal approach should be the choice of treatment in an intra- and suprasellar extension of the cysts with sellar enlargement.(ABSTRACT TRUNCATED AT 250 WORDS)

Neonatal brain tumor is rare, but is so important a disease when considering the pathogenesis of the brain tumor that numerous review articles have been described. Today, the availability of noninvasive imaging procedures such as CT and MRI make it easy to diagnose, and some successful operative cases have been reported. We report three cases of neonatal brain tumors presented clinically within the first 2 weeks. Case 1: A full term boy admitted with projectile vomiting, enlarged head and left peripheral type facial palsy at the age of 12 days. CT scan revealed a large heterogeneous mixed-density mass in the left cerebellar hemisphere. Partially removed surgical specimen consisted of primitive glial cells differentiating with the ependymal cell immunohistochemically and electron microscopically, and diagnosed as ependymoblastoma. He had whole brain irradiation postoperatively, but died from respiratory distress 7 months later without tumor regrowth indicated on CT. Case 2: A full term boy admitted with progressive enlarging of the head at the age of 10 days. CT scan revealed a high-density mass in the cerebellar vermis and an obstructive hydrocephalus. Partially removed surgical specimen, diagnosed as medulloblastoma. He was irradiated throughout the whole brain and spinal cord, but died from intracranial dissemination 5 months later. Case 3: A 32-year-old female multipara was diagnosed as hydramnion during 28 weeks gestation. The concentration of AFP was very high in the amniotic fluid. A premature female fetus, weighing 1,650 g, was delivered by cesarean section for premature separation of the placenta during an estimated 30 weeks gestation.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied the clinical, biochemical, and genetic features of eight patients with the autosomal recessive mitochondrial syndrome mitochondrial neurogastrointestinal encephalomyopathy (MNGIE). MNGIE is clinically characterized by ophthalmoparesis, peripheral neuropathy, leukoencephalopathy, gastrointestinal symptoms (recurrent nausea, vomiting, or diarrhea) with intestinal dysmotility, and histologically abnormal mitochondria in muscle. Brain MRI scans were consistent with leukodystrophy in seven patients examined. Nerve conduction and EMG studies were compatible with a sensorimotor neuropathy; quantitative EMG of two patients suggested a myogenic process. Muscle mitochondrial enzyme analysis revealed a partial defect of cytochrome c oxidase activity in five patients; three had additional respiratory chain enzyme defects. Two patients had isolated complex I defects, and one had normal respiratory chain function. Southern blot analysis revealed multiple deletions of mitochondrial DNA in four of eight patients.

From 1982 to 1991, there were 57 patients diagnosed with various intracranial disorders manifested initially with acute hemiplegia at the Department of Pediatrics, National Taiwan University Hospital. There were 33 boys and 24 girls, aged 12 days to 18 years old. In etiological consideration, cerebrovascular disease (66.7%), intracranial tumors (12.3%) and head trauma (10.5%) accounted for most of the cases. Besides acute hemiplegia, cranial nerve palsy (47.4%), disturbed consciousness (42.1%), headache (42.1%), vomiting (31.6%), focal seizure (21.1%) and fever (21.1%) were also common manifestations. Neuroimage studies of CT/MRI scan and angiography were the most useful diagnostic tools. Treatment modalities included medical treatment in 25 patients and surgical intervention in 16 patients and supportive treatment in the others. There were 12 fatal cases, half of whom died directly of intracranial pathology. The survivors exhibited various neurological deficits, in which motor deficits, mental retardation, and subsequent seizures were the three most common sequelae.
