The occurrence sites of intracranial primary germ cell tumors are most often the pineal and suprasellar regions. The histological type observed most frequently in these tumors is germinoma. Cases of embryonal carcinoma arising in the basal ganglia are rarely reported. To our knowledge, only 4 such cases have been previously reported in the literature. A case of an embryonal carcinoma arising in the basal ganglia is reported. A 17-year-old boy was admitted to our hospital on July 30, 1988 because of headache and vomiting, and a right hemiparesis. On admission, physical inspection showed no abnormalities and neurological examination revealed obtunded consciousness, a right central facial paresis and a right hemiparesis with Hoffman and Babinski reflexes. Noncontrast CT scan showed a large mass of low-to slightly high-density in the region of the left basal ganglia accompanied with midline shift and ventricular dilatation. Enhancement of the lesion was made by contrast CT scan. It was not homogeneous. Cerebral angiogram displayed a contralateral shift and an unrolling of the anterior cerebral artery, a lateral stretch of middle cerebral artery, a downward stretch of anterior choroidal artery and a tumor stain fed by the Heubner artery. On August 3, left frontotemporal craniotomy was performed. The tumor was totally removed in a piecemeal manner using microsurgical techniques. Histopathological diagnosis was mixed-type of germ cell tumor comprising embryonal carcinoma and teratoma. Postoperative CT scan showed complete disappearance of the tumor. A course of radiation of 4950 rads and two courses of a combination chemotherapy with cis-platinum, vinblastine and bleomycin were given within 3 months after the operation.(ABSTRACT TRUNCATED AT 250 WORDS)

We report two rare cases of post-irradiation vasculopathy of intracranial major arteries in children. A 13-year-old girl suffered from transient right hemiparesis 1 year after irradiation for suprasellar germinoma. Left carotid angiograms revealed marked stenoses of the intracranial internal carotid, middle cerebral, and anterior cerebral arteries, which were previously normal, and moyamoya vessels. A 2.5-year-old girl underwent internal irradiation with 198Au colloid for cystic craniopharyngioma. At the age of 10 years, she suddenly became unconscious after vomiting. Computed tomographic scans showed a right frontal intracerebral hematoma. Right carotid angiograms disclosed complete obstruction of the intracranial internal carotid, middle cerebral, and anterior cerebral arteries and moyamoya vessels, previously not present. The danger of radiation therapy causing occlusive vasculopathy in small and major cerebral arteries in children is emphasized. To prevent permanent ischemic neurological deficits, vasculopathy should be treated either medically or surgically as early as possible.

A female patient who had clinical characteristics of MELAS but with no apparent muscle symptoms was reported. She was in good health until 12 years and 5 months of age when she began to have afebrile generalized tonic-clonic convulsions. Thereafter, she had repeated stroke-like episodes, including headache, vomiting, convulsions, hemiparesis and left ehemianopsia. She had neither muscle weakness, fatigability nor atrophy. Laboratory examinations disclosed elevated lactate and pyruvate levels in the serum and cerebrospinal fluids, transient focal low density areas on brain CT and right sensorineural deafness by audiometry. No ragged-red fibers (RRF) were found in the first biopsy at 13 years and 6 months of age, and two RRF-like fibers containing red granular materials in the subsarcolemnal regions in the second at 15 years and 3 months of age. A biochemical assay on the two biopsied muscles demonstrated normal enzyme activities in the mitochondrial electron transport system. She was diagnosed as having MELAS because of remarkable mitochondrial abnormalities in smooth muscle cells in the intramuscular arterioles which were clearly demonstrated by succinic dehydrogenase (SDH) stain and on electron microscopy. It was suggested that the stroke-like episodes in this patient were induced by a preferential damage to the mitochondria in the blood vessel walls. Thus, we conclude that a simple method of identifying the strongly SDH-reactive blood vessels (SSV) in frozen sections is critical in supporting or making diagnosis of MELAS.

A 12 year old girl with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke like episodes (MELAS) is reported. After a normal childhood, at 9 years of age she developed generalized and hemilateralized seizures. Posteriorly, these episodes became more frequent and were accompanied by headache, homonimous hemianopsia, ataxia, vomiting, photophobia, left hemiparesis, slurred speech and even convulsive status. Laboratory tests evidenced lactic acidosis, brain lucencies at CT Scan and ragged skeletal muscle fibers at muscle biopsy.

Although arteriovenous malformation (AVM) is considered a congenital disease, few cases of AVM are manifested clinically in the neonatal period. In this paper a neonatal case of AVM manifested as intracranial hemorrhage is reported. A newborn female infant 12 days after birth, was admitted to a hospital with the chief complaint of sudden onset of vomiting and fever. Neurological examination revealed left hemiparesis with bulging of the anterior fontanel. CT examination demonstrated a large mass lesion with hemorrhage in the right parietal lobe. The lesion was enhanced with contrast medium. Consent for surgery was not able to be obtained from her family, so she was treated conservatively. A gradually enlarging cyst surrounding the mass appeared in follow-up CT examination. Her left hemiparesis and bulging of the anterior fontanel remained unchanged, and a rather good general health condition was maintained. Consent for surgery was finally obtained from her parents and the patient was transferred to our hospital three months after the onset of the symptoms. Cerebral angiogram showed AVM with a big aneurysmal sac. The feeder arteries of the AVM arose from the right middle cerebral artery and the anterior cerebral artery. The drainers poured into the superior sagittal sinus. AVM was removed totally by right parietal craniotomy on the 24th January, 1989. Postoperatively, her left hemiparesis started to improve gradually. Her general condition was also good, and she showed no neurological deficits at the age of 8 months.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty-one consecutive cases of intracerebral hemorrhage (ICH) in the elderly (over 70 years at the onset) were reported with special reference to neurological evaluations, prognosis and mortality in the acute phase. There were 11 men and 20 women with ICH, who were admitted to the Yokufukai Geriatric Hospital within 24 hours after the onset of ICH. Their ages at the onset ranged from 71 to 93 years with a mean of 81.1 years. The lesion location showed 5 cases with thalamic hemorrhage, 4 cases with putaminal hemorrhage, 6 cases with subcortical hemorrhage, 7 cases with cerebellar hemorrhage, 8 cases with mixed hemorrhage and 1 case with unclassified hemorrhage. 61.3% of all cases showed the onset during daytime but the remaining awoke in the morning with their symptoms or had the onset from the stage of the bedridden state. The classical prodromal symptoms headache and nausea or vomiting were found in 30% and 54.8%, respectively. Two cases with cerebellar hemorrhage were accompanied by vertigo. Twenty-four patients had consciousness disturbance at admission. There were 18 cases with right or left hemiparetic symptoms, 5 cases with tetraparesis, and 5 cases without motor dysfunction. The remaining already had hemiparesis due to old stroke. Patients with mixed hemorrhage usually exhibited conjugate deviation. In 9 of 31 cases there were mental symptoms such as wandering or night delirium. The 30-day mortality rate was 64.5% and sixty-five percent of them died within 6 days after the onset of ICH. Consciousness at admission was the overwhelming predictive factor.(ABSTRACT TRUNCATED AT 250 WORDS)

All brain tumours diagnosed since 1967 in a University Hospital in the Southern region of Brazil were reviewed and clinical information concerning age, sex, symptoms and evolution were analysed. 88.1% of tumours were primary neoplasms and the rest secondary deposits. There was a male predominance and the second and fifth decades of life were the most affected. The main presenting symptoms were headache, vomiting, hemiparesis, loss of vision and epilepsy. The commonest tumour was of astrocytic origin (36.3%) amongst which the malignant ones, including glioblastoma multiforme, predominated. These tumours were frequent in the cerebral hemispheres (31.3%), particularly in the frontal lobes. The time of evolution from the beginning of the clinical manifestations until the first hospital admission was also studied. The authors discuss the clinical and pathological observations in relation to other large series analysed in the literature.

Seven patients with delayed traumatic epidural and subdural haematomas who were treated at the Neurosurgical Centre, Nijmegen between 1975 and 1985 were reviewed. There were 3 males and 4 females with ages ranging from 16 to 70 years. Clinical signs which necessitated re-investigation in these patients included deteriorating level of consciousness in 3 patients, progressive hemiparesis in 1; extensor motor response and pupillary dilatation in 1; bradycardia in 1; and vomiting, severe headache and fits in 1 patient. Analysis of the initial CT-scan or angiography films demonstrated cerebral contusion in 4 patients and skull fractures in 5 cases. Of the 5 skull fractures there was a minor depression in 2 cases.

A five-year-old male was admitted to the hospital with generalized seizures. Enlarged lymph nodes raised the suspicion of cat-scratch disease. The diagnosis was confirmed by a positive history of a cat bite, typical histopathologic findings in the biopsy of the lymph nodes, and a positive skin test. Brain CT scan and LP were repeatedly normal. The clinical course was remarkable for recurrent episodes of status epilepticus refractory to usual anticonvulsant therapy and prolonged encephalopathy consisting of mental confusion, hemiparesis, tremor, chorea, and vomiting. All neurologic symptoms gradually resolved within nine months, without sequelae. Cat-scratch encephalopathy should be suspected in a child presenting with status epilepticus and enlarged lymph nodes. Aggressive and prolonged anticonvulsant therapy is strongly recommended.

In a 37-year-old female patient complaining of increasing pain in the neck and occiput, chiropractic manipulations at the cervical vertebral column were associated with ischaemias of the brain stem presenting as vertigo, transient "locked-in" syndrome followed by vomiting, and sensorimotor hemiparesis. Digital subtraction angiography (DSA) revealed complete obstruction of the right and slight dissection of the left vertebral artery. The symptoms receded within a few days after heparinisation with 1000 IU/h intravenously. A 39-year-old female patient developed vertigo, nystagmus, tetraparesis and dysarthria two days after chiropractic intervention because of refractory pain in the neck and occiput. DSA showed embolism of the basilar artery and extensive dissections of the vertebral arteries. The basilar artery was completely recanalized after local intraarterial fibrinolysis with 50,000 IU urokinase. During the further course of treatment the symptoms receded under heparin and phenprocoumon over a period of 8 months, except for hemiparesis on the left side especially affecting the arm. Trivial traumas can result in dissections of the vertebral arteries. Severe neck pain is a frequent, typical early symptom. Hence, patients with cervical vertebral column syndromes should receive chiropractic treatment only after careful diagnosis.
