Aneurysm of the vein of Galen is a very rare disease. The authors present a case of secondary aneurysm of the vein of Galen which was confirmed by characteristic clinical symptoms, brain CT and angiographic findings. The patient was a 14-year-old right handed girl with intermittent headache, nausea, vomiting, dysphasia and gait disturbance. Neurologic examination revealed dysarthria, nasal voice, blurring of both margins of optic discs, truncal ataxia and dysdiadochokinesia. Sensory function was normal but right hemiparesis was seen. Roentgenogram of the skull revealed diffuse thinning of the calvarium, widening of sella turcica and erosion of clinoid processes. Computed tomogram of the brain showed dilatation of all ventricles and round hyperdense mass behind the third ventricle in the midline. The lesion was enhanced markedly and homogeneously. Left and right internal carotid angiograms showed arteriovenousmal-formation with drainage to the aneurysm of the vein of Galen.

The authors reported the clinical course and the postmortem examination of a unique case of neurocutaneous melanosis with numerous anomalies and complications, which included congenital dislocation of lenses, hypogonadism, ectopia of prostatic duct, genuine phimose, retentio testis, psina bifida and neurogenic bladder. This 13-year-old boy with a large hairy nevus in a bathing trunk configulation and multiple small nevi over the whole body since his birth was admitted to our hospital for evaluation of headache and vomiting. Neurological examination showed bilateral papilledema and slight left hemiparesis. A CT scan revealed a large right frontal mass and craniotomy was performed with subtotal removal of this tumor which was confirmed as a malignant leptomeningeal melanoma. He initially made uneventful postoperative recovery, and two courses of chemotherapy with DTIC, ACNU and VCR were given; however, the currence of brain tumor ensued shortly thereafter, and he died in approximately six months after the onset of intracranial symptoms despite of the third course of chemotherapy. Thirty five cases of neurocutaneous melanosis associated with or without malignant melanoma have been reported in Japan. Twenty-eight cases were male and 7 female. Two cases showed the evidence of primary malignant melanoma outside of the central nervous system, whereas twenty eight leptomeningeal melanoma, in which 22 were solid and 6 diffuse, were shown intracranially. Other 5 cases had epileptic seizure and/or hydrocephalus caused by wide spreaded leptmeningeal melanosis. This high incidence of intracranial malignant melanoma in this disorder was remarkable compaired with the previous reports in other countries. Mean duration between deaths and the onset of symptoms of intracranial hypertension or focal neurological signs was 7 months, ranging from 1 to 24 months, showing the rapidly deteriorating course in this disorder.(ABSTRACT TRUNCATED AT 250 WORDS)

A 61-year-old woman is presented with a bilateral total ophthalmoplegia as an initial ocular symptom, caused by a midbrain hematoma. She complained of acute headache, nausea, vomiting and bilateral closure of her eyelids. Examination on admission showed meningeal irritation; mild consciousness disturbance; bilateral total ophthalmoplegia; left hemiparesis; ataxia in all extremities, more marked to the left. Computed tomography demonstrated a small hematoma in the midbrain tegmentum. Angiography demonstrated midbrain arteriovenous malformation, and she was treated conservatively. Abduction of both eyes and adduction of the left eye appeared on the next day of the ictus, and after that, improved gradually. Left ptosis had improved since one week after the ictus. Light reflex of the left pupil had seen 5 days after the ictus. At the same time, the left pupil revealed an oval-shape. Right internal ophthalmoplegia continued to exist. One year later, the right eye deviated externally, and the left deviated inferio-medially. Abduction of both eyes was normal. Infraduction of both eyes was seen, but limited on the left. Upgaze paresis remained unchanged, and adduction of the right eye was absent. Adduction of the left eye showed almost full recovery. There was right complete ptosis, but left ptosis became indefinite. These ocular findings indicated typical right oculomotor paresis plus superior rectus paresis of the left eye, which suggested a destructive lesion in the right oculomotor nucleus. Also, her left extremities showed a hemiparesis as a pyramidal tract sign (Weber's syndrome) and an ataxia as a cerebellar sign (Claude's syndrome).(ABSTRACT TRUNCATED AT 250 WORDS)

A 67-year-old man was admitted for status epilepticus, right hemiparesis, repeating vertigo and vomiting. Computed tomography showed no abnormality except for slight brain atrophy. Angiogram demonstrated bilateral vertebral artery stenosis at the origin, especially on the left side, and bilateral cervical internal carotid artery stenosis associated with ulceration. Intracranially, bilateral anterior cerebral artery was filled only by right internal carotid artery. Internal carotid artery on both sides did not fill the posterior cerebral artery. From these findings, we thought that both bilateral internal carotid artery and left vertebral artery should be surgically reconstructed. On June 4, 1986, left vertebral transposition to the common carotid artery and left carotid endarterectomy using double-balloon shunt were performed. Waiting for recovery of the general condition, right carotid endarterectomy was carried out on June 27, 1986. Postoperative angiogram demonstrated disappearance of bilateral internal carotid artery stenosis, and good filling of left vertebral artery through left common carotid artery. Postoperative course was uneventful and right hemiparesis gradually improved. Vertigo and vomiting completely subsided. The method and indication of combined reconstruction for extracranial vertebral and carotid artery were discussed.

A rare case of extracranial internal carotid occlusion with a coexisting ipsilateral internal carotid aneurysm is reported. A 50-year-old male had a sudden onset of severe headache, vomiting and right motor weakness on May 14, 1984. Two days later the patient was transferred to our hospital. On admission he was alert but presented with nuchal rigidity and right moderate hemiparesis. He had an episode of a blunt head injury 12 years previously, but no history of hypertension, diabetes mellitus or cerebral stroke. A computed tomography revealed mild subarachnoid hemorrhage and mild ventricular dilatation. A cerebral angiography did not demonstrate any aneurysms but it revealed occlusion of the right internal carotid artery at the cervical bifurcation. The repeated angiography on May 31 disclosed a saccular aneurysm arising anteromedially at the level of the junction of the right posterior communicating artery and the internal carotid artery. The cervical internal carotid artery remained occluded at the same site. The middle cerebral artery was supplied through the well-developed posterior communicating artery, and the right anterior cerebral artery was supplied through the anterior communicating artery. Clipping of the aneurysm was attempted but it was forcibly trapped because of premature bleeding on June 5. The right V-P shunt was performed for the progressive ventricular dilatation on June 12. The patient was discharged with no paresis on June 20. It has been well known that the uni- or bilateral carotid occlusion, whatever the origins are, are often associated with cerebral aneurysms.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of cystic cerebral tuberculoma is presented. A 63-year-old man was admitted initially to a sanatorium in May, 1983, for the treatment of pulmonary tuberculosis. He developed headache and vomiting, and suddenly had a right hemiconvulsion on September 27, 1983. Gradually he developed right hemiparesis and motor aphasia. CT scan revealed a well defined, ring-like enhanced mass with multiloculated cysts in the left fronto-parietal lobe. So, he was transferred to our hospital on February 3, 1984. Neurological examination revealed that he had motor aphasia and right hemiparesis. Left carotid angiogram showed light tumor stain in the left fronto-parietal lobe, and 99mTc brain scan detected increased uptake in this area. A left fronto-parieto-temporal craniotomy was performed and a subcortical mass was excised en bloc. The mass had multiloculated cysts containing xanthochromic fluid. Histologically, the mass was cystic cerebral tuberculoma. Cystic cerebral tuberculomas have rarely been reported even before the introduction of antituberculous chemotherapy. The pathogenesis of the cysts in this particular case was considered that the caseous material would have undergone liquefaction by enzymes liberated from degenerated and fragmented inflammatory cells.

In proportion to a rapid increase of dialysis patient, death caused by neurological complications is increasing annually among long-term hemodialyzed patients. A case of chronic subdural hematoma during long-term hemodialysis is presented. A 35-year-old male had undergone hemodialysis three times weekly for four years. He had marked changes in body-weight and blood pressure between hemodialysis. In March 1983, he had a headache, vomiting, and left hemiparesis. The CT scan showed a right subdural hematoma. He was admitted to our hospital 10 days later because of progressive hemiparesis and speech disturbance. The neurological examination showed left hemiparesis with sensory deficit and dysarthria. The CT scan showed an increase in the size of the subdural hematoma. Bleeding time was over 10 minutes. A right-sided burr hole was made and altered blood was removed and irrigated. After operation, headache and weakness rapidly subsided, but the next morning, attacks of convulsion occurred. The CT scan showed the rebleeding in the subdural space. After correcting the level of serum potassium by hemodialysis, a right parietal craniotomy was performed. Hematoma of about 100 g was removed and the capsule of the hematoma showed organized tissue histologically. Postoperatively, although attacks of convulsion occurred temporarily, he gradually improved. The levels of serum potassium and BUN were controlled by several treatments of hemodialysis. He was discharged with only mild hemiparesis. Subdural hematoma caused by hemodialysis is a very important complication. Chronic subdural hematoma is sometimes very difficult to differentiate from dysequilibrium syndrome or dialysis dementia. The CT scan is a very valuable examination to rule out subdural hematoma.

We analyzed 26 cases of primary lymphoma of the central nervous system. There were 14 males and 12 females ranging in age from 5-76 years (median age 51 years, mean age 50.2 years). None had received organ transplantation or immunosuppressive therapy. The most common presenting symptoms were headache, mental changes, nausea, vomiting, and convulsions. The main neurological findings were hemiparesis, papilledema, visual field defects, and cranial nerve palsies. The most common finding in the cerebrospinal fluid (CSF) was high protein content; CSF cytology was positive in only one case. Computerized tomography was done in 14 cases; all showed a contrast-enhancing lesion. Angiography generally revealed an avascular mass. The most common location above tentorium was the frontal lobe; in four cases the tumor was infratentorial (cerebellum, 3 cases). In five cases there was diffuse involvement of the brain; all had severe dementia and diagnosis was not made until the autopsy. Histologically, the most common type was diffuse histiocytic or immunoblastic lymphoma according to Rappaport and the Working Formulation classification respectively. Radiation therapy alone in five patients gave a median survival of 17 months. Five patients received radiation and chemotherapy, and median survival was 16 months. Two patients developed ocular lymphoma 8 and 36 months later that was treated by radiation.

A 6 1/2-month-old male offspring of consanguineous Egyptian parents was first seen because of fever, somnolence, vomiting, right focal motor seizures, right hemiparesis, elevated transaminase levels, hyperammonemia, and acidosis. A computed tomographic scan of the head suggested swelling of the left cerebral hemisphere, and an electroencephalogram indicated left frontotemporal abnormalities, but brain biopsy demonstrated diffuse white matter spongiosis and gliosis. Subsequently, urine organic acid analysis and enzyme assays were diagnostic of 3-hydroxy-3-methylglutaryl-coenzyme A lyase deficiency.

A case of meningioma following irradiation for a tumor of the third ventricle is reported. A four year old girl was admitted complaining of headache and vomiting. The pneumoventriculography revealed marked hydrocephalus and a mass lesion at the third ventricle. Under the diagnosis of a tumor of the third ventricle, ventriculo-atrial shunt and radiation therapy were performed. Totally, 4170 rad irradiation was directed from left temporal area through a single portal. Though she had no complaints for fourteen years, at the age of eighteen, she was admitted complaining of right hemiparasis and general convulsion. CT scan and left carotid angiogram revealed a left fronto-temporal tumor diagnosed as meningioma. Histological examination showed transitional type meningioma. The post-operative course was uneventful, and discharged without neurological sign except for slight right hemiparesis. A review of available literature revealed about 150 cases of post irradiated meningiomas. However, there were only 18 cases of meningiomas following irradiation for the treatment of brain tumors. These reported cases were also discussed.
