Thymoma with extrathoracic metastasis is very rare, especially to the central nervous system. As far as we know, this is the 15th reported case of cerebral metastasis from malignant thymoma. The prognosis is very poor and almost all of them die in one to one and half years. We have experienced such a case, who is 56 years old man, presenting Gerstmann's syndrome and right-
hemiparesis
8 months later after thoracotomy for removal of thymoma. At the admission time in this hospital, CT findings proved the tumor in the left temporoparietal area, left ventricle deformity and slight midline shift to right side. The average of CT density in the low density area was 20. Peripheral region of the tumor was enhanced by contrast CT. Left carotid angiography showed the ACA shift to the right side and abnormal vascularity of peripheral branches of angular artery (arterial phase) and also tumor strain in late artery (arterial phase) and also tumor strain in late arterial phase. Brain scintigram revealed accumulation in the left parietal region. The rt-
hemiparesis
was rapidly going to be rt-
hemiplegia
. Therefore, we have performed needle puncture to prevent rt-
hemiplegia
at the first time. In the course of needle puncture, 90 ml of dark and red fluid was gained at 3.0 cm depth from the cerebral surface. Immediately, the above two symptoms have improved remarkably. Post operative CT showed the reduction of tumor and improvement of the midline shift. The radical operation have been done 2 days after the needle puncture. The tumor was elastic-soft and hemorrhagic and appeared dark-red.(ABSTRACT TRUNCATED AT 250 WORDS)

Central nervous system is often involved by herpes zoster but it is very rarely seen that contralateral
hemiparesis
or
hemiplegia
developed after herpes zoster ophthalmicus. We report a case of herpes zoster ophthalmicus followed by the delayed contralateral
hemiparesis
. A 33-year-old man developed acute cerebral infarction and resultant right
hemiparesis
44 days after herpes zoster ophthalmicus in the left side. Brain CT disclosed hypodense area in the left basal ganglia. Cerebral angiography revealed segmental narrowing of M1 portion of the right middle cerebral artery.

The effect of the opiate antagonist naloxone on both the neurological deficit and regional cortical blood flow after middle cerebral artery occlusion in the cat was investigated. In animals with mild symptoms, naloxone did not consistently produce a significant behavioral effect. In all cats with neurological deficits, including
hemiplegia
or severe
hemiparesis
, 2 mg/kg naloxone administered intravenously 4 h after the ischemic lesion produced a reversal of neurological symptoms. This effect began within 2 min following naloxone injection and lasted for approximately 20 min. Animals were then anesthetized and cortical blood flow was measured by the hydrogen clearance method. Average cortical blood flow on the side of the occlusion was 50% that of the control side. Naloxone produced a significant additional decrease of 19.5% in cortical blood flow in the ischemic hemisphere, whereas no effect on blood flow on the control side was noted. Thus, although naloxone appears to temporarily reverse the severe neurological deficits resulting from middle cerebral artery occlusion in the cat, this effect appears to be accompanied by a decrease in local blood flow to the ischemic cortex.

The results of psychological testing, EEGs and CT scans were examined for 41 children with congenital or early acquired
hemiplegia
. On average, IQ was depressed and the magnitude of this depression was highly correlated with lesion size, degree of
hemiparesis
and EEG abnormality, but not with location of lesion. There were no significant effects of lesion laterality on Verbal vs. Performance IQ on Wechsler tests. However, receptive vocabulary, as measured by the Peabody Picture Vocabulary Test, was differentially depressed by left-hemisphere damage. Further, on a variety of verbal tasks, patients with congenital lesions performed better than those with acquired lesions. In contrast, no significant differences were found between the two groups on spatial tasks.

A 12-year-old boy developed complete right
hemiplegia
and 7th cranial nerve palsy 2 days after laparotomy for a perforated appendix. Full recovery took 2 months. Although it can be accepted that the
hemiparesis
was not caused by acute appendicitis it is postulated that this unusual association was due either to a septic embolus which lodged in the region of the internal capsule or to a minor cerebrovascular accident.

Cerebral ischemia was recorded in 1.9% of 1277 patients with myocardial infarction. In most cases ischemia involved the carotid artery system, usually causing a
hemiparesis
or
hemiplegia
. Patients were mostly elderly, and the ischemic episode worsened their prognosis. The pathogenesis was surely often of embolic origin but several facts suggest that other mechanisms were also involved. Anticoagulant therapy, at least in the form in which it was used in these patients, i.e. subcutaneous administration of calcium heparin 5000 I.U. b.i.d. for thrombophlebitis prophylaxis, does not seem to prevent these complications.

Cortical and cervical stimulation has been performed in 20 patients with
hemiparesis
or
hemiplegia
due to hemispheric infarction and in 20 control subjects. The motor action potentials (MAPs) were recorded from biceps and thenar muscles. MAPs evoked by stimulation of the undamaged hemisphere were normal in 18 out of 20 patients and in two there was a slight increase of central conduction time (CCT). The stimulation of the motor cortex of the damaged hemisphere did not evoke any response in 15 patients; in two the MAPs were absent in one muscle and in the remaining three were delayed in one or both muscles. Cervical MAPs were normal in 18 patients and delayed in the thenar muscle in two patients.

A case of Eales' disease with
hemiplegia
is reported. The patient had a right
hemiparesis
and a left
hemiplegia
occurring after a sudden loss of vision in the left eye two years earlier. The diagnosis was based on fluorescein angiography showing neovascularisation, fluorescein leakage, perivascular sheating and hemorrhages and on CT scan showing multiple hypodense lesions in right and left hemispheres and on IDSA showing bilateral occlusion of anterior cerebral arteries. The patient did not have further relapses.

A 34-year-old male developed consciousness disturbance; semicoma, on December 15, 1984, and diagnosed as a thalamic hemorrhage perforating into the ventricular system after a computed tomographical (CT) examination. Angiography revealed an arteriovenous malformation (AVM) in the right posterior thalamic region, which was fed by a posteromedial choroidal artery. He was transferred to our neurosurgical clinic on February 18, 1985. On admission, he was alert, however, disorientation and slight mental retardation were seen as well as Parinaud's sign. Mild left
hemiparesis
was also detected with equivocal hypesthesia on the left lower limb. The AVM was subtotally removed on March, 12, via transventricular approach after right parietooccipital craniotomy. Consciousness disturbance (drowsy) and left
hemiplegia
developed after the operation, however, these deteriorations were transient, recovering to the preoperative or better status by 2 weeks after the operation. Postoperative repetitive examinations of the sensory perceptibility of various modalities revealed remarkable disturbance or complete loss of perception in joint and vibration senses (0-3/10 compared to the healthy left side). Touch sensation was also severely deteriorated (0-3/10) on the affected extremities. The disturbances in these modalities of the sensation did not show any trend to improve until the time of discharge on 57th postoperative day. On the other hand, pain and temperature sensations were less remarkably disturbed (5-8/10), and with tendency of gradual improvement. Estimation of the range of lesion by the CT scan with projecting on the Schaltenbrand & Bailey's atlas revealed that the nucleus ventralis caudalis, centre-median nucleus and pulvinar thalami were involved.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of cardiac myxoma presenting as metastatic brain tumor are reported. The patient was a 44-year-old man. One year prior to this admission, he had suffered stroke, which was characterized by right
hemiparesis
and dysarthria. The computed tomographic (= CT) scan of the head at that time showed a low density on the left basal ganglia and the echocardiogram suggested a left atrial myxoma. At surgery, a polypoid myxoma attached to the atrial septum was totally removed. Right
hemiparesis
was improved and the patient was discharged. A few months later, the patient was evaluated for multiple cutaneous masses and diagnosed by biopsy as metastatic myxoma. The patient's condition remained unchanged until this admission. In March 1985, the patient had a tonic-clonic convulsion marching from right hand and developed right
hemiplegia
with drowsy. An echocardiogram failed to reveal recurrence of the cardiac myxoma. A CT scan revealed a 5-cm, relatively circumscribed, low density mass in the left fronto-parietal lobe, ring mottled enhancement after contrast administration and more enhancement in the delayed scanning of 45 min. Craniotomy showed a tender, friable tumor with a yellowish cyst fluid, but apparently not invading the brain parenchyma. After complete excision of the mass, there was rapid lessing in the
hemiplegia
and improvement in the level of consciousness. A contrast-enhancement CT scan performed 2 weeks after craniotomy revealed no evidence of residual tumor. Pathohistological examination showed spindle-shaped and stellate cells which formed clusters and contained large amounts of acid polysaccharides as demonstrated by the alcian blue method.(ABSTRACT TRUNCATED AT 250 WORDS)
