In two patients admitted to hospital-one with signs of cerebral infarction, the other with headaches, vertigo and paraesthesias-the TPHA test was "reactive", while the 19S(IgM)-FTA-ABS test was not. There was no cerebrospinal fluid (CSF) pleocytosis. Further CSF analyses and serological tests for syphilis (including CSF protein profile, demonstration of oligoclonal IgG, quantitative determination of Treponema-specific antibodies in serum and CSF) confirmed the diagnosis of neurosyphilis requiring treatment. In both patients the biologically false-negative 19S(IgM)-FTA-ABS test at first became transiently reactive after treatment. This unusual finding was probably due to antigen, liberated by treatment, again stimulating previously blocked IgM antibody synthesis. The listed additional tests should be performed in all patients with a reactive TPHA test and neurological or psychiatric signs and symptoms.

Traumatic dissections of the extracranial internal carotid artery (ICA) in 18 patients aged 19 to 55 years were studied. All had suffered blunt head or neck injury of marked or moderate severity; motor-vehicle accidents were the leading cause of the injury. Delayed focal cerebral ischemic symptoms were the most common presenting symptoms. Less commonly noted was focal unilateral headache associated with oculosympathetic paresis or bruit. Following a head injury, the abrupt onset of focal cerebral symptoms after a lucid interval should raise the suspicion of arterial injury, particularly when computerized tomography fails to show abnormalities that would explain the evolving neurological deficits on the basis of direct trauma to the brain. Unilateral headaches, oculosympathetic palsy, and bruits also help in establishing the diagnosis. Focal cerebral ischemic symptoms may develop months or years after the initial trauma. These delayed symptoms are caused by embolization from a thrombus within a residual dissecting aneurysm. Common angiographic findings, in decreasing order of frequency, are: aneurysm, stenosis of the lumen, occlusion, intimal flap, distal branch occlusion (embolization), and slow ICA-to-middle cerebral artery flow. Although two patients died as the result of massive cerebral infarction and edema and some were left with severe neurological deficits, most made a good recovery. Residual dissecting aneurysms and occlusion seem to occur more frequently with traumatic dissections than with spontaneous dissections of the extracranial ICA.

Cerebral aspergillosis is one of the most common mycotic infections in the central nervous system causing different clinical features such as brain abscess, granuloma, meningitis, and encephalitis. Cerebral aspergillosis, however, may lead to a cerebral vascular accident such as intracranial hemorrhage or cerebral infarction. In this report, we present two patients with cerebral aspergillosis accompanied by intracranial hemorrhage. A total of 124 reported cases of cerebral aspergillosis are reviewed to ascertain the pathogenesis of the associated vascular lesion. The first patient was a 9-year-old girl, who developed drowsiness with a headache during the medical treatment for acute myelocytic leukemia. CT disclosed subarachnoid and intraventricular hemorrhage. The autopsy revealed that the aspergillus arteritis was the cause of repeated hemorrhage. The second patient was a 15-year-old boy with allergic purpura and renal failure, who suddenly developed a stupor with convulsive seizure. CT disclosed an intracerebral hemorrhage in the right parieto-occipital area. The patient gradually deteriorated and died in spite of the surgical removal of the hematoma. The autopsy revealed that the hemorrhage was caused by the aspergillus arteritis. Cerebral aspergillosis has two routes of infection to the central nervous system: hematogenous dissemination from the distant site (usually the lung) and direct extension from the contiguous site (usually the paranasal sinuses or orbit). The primary mechanism of neuropathology is different between these two types. Primary cerebral arteritis is most often seen in patients with the former type, whereas primary basal meningitis occurs in the latter. The incidence of clinico-pathological features is different between hematogenous dissemination type and direct extension type.(ABSTRACT TRUNCATED AT 250 WORDS)

We obtained CTs in 259 patients with a first alcohol-related convulsion. Each subject had generalized convulsions, recent abstinence from alcohol abuse, and no obvious etiology for seizures other than alcohol withdrawal. Patients with only focal seizures, major head injury, coma, or a severe toxic-metabolic disorder were excluded. We recorded history and signs of minor head injury, presence of headache, level of consciousness, neurologic signs, routine medical examination findings, and subsequent clinical course. Sixteen patients (6.2%) had intracranial lesions on CT. Eight had subdural hematomas or hygromas, two had vascular malformations, two had neurocysticercosis, and one each showed a Berry aneurysm, possible tumor, skull fracture with subarachnoid hemorrhage, and probable cerebral infarction. In ten cases (3.9%), clinical management was altered because of the CT result. History or signs of minor head trauma, headache, level of consciousness, or focal neurologic signs did not significantly correlate with CT abnormality.

Two cases of spontaneous dissecting aneurysm extending from the supraclinoid portion of the internal carotid artery to the middle cerebral artery are reported in two teenaged patients. Both patients collapsed with a headache on the right side, left hemiparesis, and altered consciousness due to cerebral ischemia. One patient became alert in 2 days; however, his condition rapidly deteriorated 4 days later and he died on the 8th day from massive cerebral infarction. The other patient received a right superficial temporal artery (STA)-middle cerebral artery (MCA) anastomosis 50 hours after his initial symptoms. He improved gradually and is able to walk without help. Cerebral angiograms 3 months after the operation disclosed progressive attenuation of the MCA and dilatation of the anastomosed STA. Artificial collateral flow demonstrated in the postoperative angiogram may have been useful in preventing massive cerebral infarction.

Despite its efficacy in preventing rebleeding, the anticipated strong trend in favor of early intracranial surgery has not been achieved. Early intracranial operation remains a useful choice in the management of recent SAH in good-risk patients, but patients must be carefully selected on an individual basis. Many patients will undoubtedly benefit from early surgery but it is not a panacea. Further investigation of surgical treatment in combination with improved preoperative and postoperative medical therapy will be required to ameliorate the outcome of SAH. In particular, the prevention and treatment of cerebral infarction deserves attention. The results of the antifibrinolytic and timing of intracranial surgery studies point to the need for an effective prevention treatment regimen for vasospasm. Further studies about the efficacy of calcium channel blocking drugs in prevention of ischemia after SAH are needed among patients given antifibrinolytic drugs or having early operation. All the advances in treatment are predicated on prompt diagnosis of SAH in good-condition patients. The medical community needs to maintain a high degree of vigilance for the diagnosis of SAH in all patients complaining of a new, unusual or severe headache. Early referral to properly equipped and staffed medical facilities remains a keystone to effective treatment of SAH.

Thirty (2.5%) of 1200 consecutive patients with a first stroke had a spontaneous dissection with occlusion of the cervical internal carotid artery (ICA). A suggestive picture with ipsilateral headache and oculosympathetic paresis was uncommon (17%), so that diagnosis was uncertain before angiography. Seven patients died within one week. During follow-up (mean, 3.2 years) with sequential Doppler ultrasonographic testing, 12 survivors had a good recovery and early reopening of the occluded ICA, and 11 had a poor recovery usually without reopening of the ICA. Recurrence of a dissection occurred in only one patient. Large infarcts causing death or a severe disability were associated with an ICA thrombus and distal emboli; the organization of this intraluminal thrombosis may explain the absence of reopening in these cases while resorption of the intramural hematoma developed. Early heparin sodium therapy may help prevent intraluminal clotting without carrying an important risk of extending the dissection, but its clinical benefit remains unproven. Contrary to current opinions, ICA dissection with occlusion causing cerebral infarction may often carry a severe prognosis.

Agarose isoelectric focusing was used to demonstrate oligoclonal bands in cerebrospinal fluid (CSF) and serum from 998 consecutive neurological patients. Compared with agarose electrophoresis, agarose isoelectric focusing was slightly more sensitive, showing more (and more easily discernible) oligoclonal bands. Agarose isoelectric focusing, which has good reproducibility, revealed oligoclonal bands in CSF in 95% of 43 patients with multiple sclerosis, 44% of 39 with aseptic meningoencephalitis, and 14% of 906 with other neurological diseases. Interestingly, oligoclonal bands were found in CSF from 12% of 162 patients with acute cerebral infarction and 23% of 53 with polyneuropathy, and also in 29% of 17 with dementia, while only 4% of 206 patients with headache, vertigo, or psychoneurosis had this CSF abnormality. We recommend this procedure for the routine examination of paired CSF and serum specimens for the presence of oligoclonal bands.

Sudden cerebrovascular insults occurred during or immediately following remission induction therapy in 4 children with acute lymphoblastic leukemia. In 3, cerebral infarction was due to thrombosis. In the fourth, an intracerebral hematoma developed representing either frank hemorrhaging or a hemorrhagic infarction. None of the patients had central nervous system leukemia or extreme leukocytosis at the time of diagnosis. Symptoms were obtundation, hemiparesis, seizures, and headache. The induction chemotherapy included L-asparaginase which causes deficiencies of antithrombin, plasminogen, fibrinogen, and factors IX and XI. These hemostatic abnormalities may explain the thromboses and bleeding observed in these children.

From January 1978 to December 1993, 73 patients with moyamoya disease were collected from seven neurological centers in Taiwan. The annual incidence of this disease in Taiwan is 0.024 per 100,000 population. There were 33 males and 40 females. The ages ranged from 2 to 62 years with a peak incidence in the 31 to 40 year age group (18 cases). Cerebral infarction occurred in 16 out of 19 juvenile patients (84.2%); by contrast, only 19 out of 54 adult patients (35.2%) presented with infarction. Hemorrhagic strokes were more frequent in adult patients. Computed tomographic scans following stroke showed cerebral infarction in 35 cases, ventricular hemorrhage in 21 cases, intracerebral hemorrhage in 11 cases and pure subarachnoidal hemorrhage in 6 cases. The most frequent initial symptom was motor disturbance (58.9%), followed by headaches (49.3%), and impaired consciousness (34.2%). Compared with reports from Japan, this survey showed a lower incidence of moyamoya disease in Taiwan.
