We report a rare case of meningioma of the parieto-occipital convexity accompanied by hemorrhage in the tumor and in the subdural space that occurred while pre-operative embolization was being applied. The patient, a 48 year old woman, presented sudden headache and, in a few minutes, comatose status and decerebrate rigidity. A quick diagnosis with CT-scan of acute intratumoral and subdural hemorrhage and a rapid intervention on the patient led to complete recovery. The possible reason for the hemorrhage is the sudden change in blood pressure of pathologic small vessels triggered by embolization.

The cyclic alternations of wakefulness and sleep competing for the domain of brain activity are controlled by neuronal systems contained in the core of the brainstem, hypothalamus, thalamus, and basal forebrain. This organization encompasses complex neuroanatomic, neurophysiologic, and neurochemical mechanisms that are subject to disruption from within, or as a result of incidental alterations of appropriate brain centers. The first section of this article reviews the wake-sleep disturbances that occur with lesions in defined neuroanatomic structures involved in sleep mechanisms, such as the brainstem, hypothalamus, thalamus, and cerebral hemispheres. The second section gives an overview of specific sleep alterations associated with neurologic disorders. These include stroke, Parkinson's disease, degenerative systemic disorders, multiple sclerosis, myotonic dystrophy, myasthenia gravis, brain tumors, head trauma, coma, epilepsy, and headache syndromes.

In this retrospective study, 11 cases of posterior fossa epidural hematoma were analyzed in terms of clinical and radiological features, treatment, and outcome. Posterior fossa epidural hematomas accounted for 11.8% of all epidural hematomas encountered during the 7-year period studied. There were eight males and three females ranging in age from 2 to 53 years (mean, 20.7 years). Glasgow Coma Scale scores on admission were relatively good in many cases. Headache and/or vomiting were common symptoms on admission, whereas cerebellar signs were rare. As all 11 cases involved trauma, occipital fractures were present in eight (72.7%). Six patients underwent surgery. The indications for surgery, in terms of computed tomography findings, were: 1) the maximum thickness of the epidural hematoma was more than 15 mm; 2) the posterior fossa cisterns (e.g., the quadrigeminal and ambient cisterns) were poorly visualized; 3) there was marked deformity and/or displacement of the fourth ventricle; and 4) the hematoma extended to the supratentorial region and severely compressed the brain. At discharge, eight patients showed good recovery and one was moderately disabled. Two patients died. The prognosis for posterior fossa epidural hematoma appears relatively good, if it is not accompanied by severe primary brainstem injury and is diagnosed early, and appropriately and promptly treated.

Thyrotoxic crisis (thyroid storm) is a rare complication of hyperthyroidism. It can be observed not only in thyroid autonomy with latent hyperfunction after exposure to iodine, but also in Graves' disease with overt hyperfunction. Adequate management of thyrotoxic crisis is still controversial. We report about four patients (four women, mean age 75 years) with Graves' disease who developed thyrotoxic crisis during therapy with antithyroid drugs so that surgical intervention became necessary. The patients had been admitted to the hospital for nonspecific symptoms such as headache, cachexy, and psychosis. Thyroid hormone levels had reached twice the normal range prior to surgery. All patients showed severe neurological deficits leading to coma. In three cases euthyroidism was achieved within two days after surgery. The neurological symptoms disappeared after an average of four days. The postoperative course did not show severe complications and all patients recovered completely. Especially in the elderly a monosymptomatic or nonspecific course of thyroid storm with neurological symptoms may represent a severe and life-threatening situation. In these cases surgery can become necessary even if euthyroidism has not been achieved preoperatively.

One hundred twelve patients presenting with a Glascow Coma Scale (GCS) score greater than or equal to 13 with a history of minor head trauma were prospectively studied to determine if certain historic or physical examination variables would predict which of these patients were at increased risk for intracranial injury. Patients either underwent cranial computed axial tomography (CT) or were followed up by phone at 4 weeks to determine major morbidity or mortality. Thirty-five patients underwent CT scanning of the head and eight demonstrated intracranial injury. Five patients were treated nonoperatively, and three patients had neurosurgical intervention. One patient died following surgery. At the 4-week follow-up no patient was found to have suffered any major morbidity or mortality. Stepwise logistic regression found age over 40 years (P = .05, odds ratio = 6.4, 95% confidence interval 1.0 to 38.8) and complaint of headache (P = .039, odds ratio 8.167, 95% confidence interval 1.074 to 62.09) to be significantly predictive of intracranial injury. All eight patients with positive CTs had a GCS score of 15. The authors conclude that intracranial injury does exist in patients suffering minor head trauma with a GCS score of 13 or above. Age over 40 years and complaint of headache are associated with an increased risk of intracranial injury.

Of the 1,805 patients with acute stroke enrolled in the Stroke Data Bank, 237 had parenchymatous hemorrhage. After excluding 34 secondary intracerebral and 31 infratentorial hemorrhage patients, a logistic regression analysis of the 172 patients with primary supratentorial intracerebral hemorrhage (ICH) elucidated clinical factors that distinguished the 65 patients with lobar hemorrhage (LH) from the 107 patients with deep hemorrhage (DH) located in the basal ganglia and thalamus. In LH, severe headache was more common than in DH, while hypertension and motor deficit were significantly less common. Patients with either LH or DH had a similar prognosis and mean Glasgow Coma Scale (GCS) scores, despite the hematoma volume measured on the initial CT being significantly greater for LH than DH. The presence of intraventricular extension (IVH) was more frequent in DH. The frequency of IVH increased with hematoma volume in LH, but remained constant for DH. Two CT variables (IVH and hematoma volume) that differed in these two hemorrhage groups were important predictors of coma (GCS less than or equal to 8) in a logistic regression model. Differences in the frequency of IVH may help explain why the degree of impairment in consciousness was similar in the two groups. Among patients with supratentorial ICH, location of the hematoma is related to both volume and IVH, which are important determinants of the level of consciousness.

A prospective study of the neurological manifestations in all patients with systemic lupus erythematous (SLE) was conducted between February 1985 to January 1989. Excluding herpes zoster infection of peripheral or cranial nerves, post-herpetic neuralgia and migraine, 36 neurological episodes occurred in 33 patients. The presenting symptoms were mental confusion (10), psychosis (five), seizures (six), focal neurological deficit (three), coma (two), headache (five), blurring of vision (three), neuropathy (one) and myelopathy (one). Of these manifestations, only eight episodes were due to primary involvement by SLE: psychosis (two), seizure (two), multiple cerebral infarcts (one), papillitis (one), neuropathy (one) and myelopathy (one). Infection was the most common secondary cause of neurological episodes: all 10 episodes of mental confusion (fungal seven, pyogenic two, tuberculous one, nocardial one); two of six seizures (tuberculous one, pyogenic one); all five headaches (tuberculous meningitis three, cryptococcal meningitis two). The other secondary causes included steroid psychosis (two), hypertensive encephalopathy with seizure (one) and hypertensive retinopathy (one). Three of five cases of focal neurological deficit were due to macrovascular disease rather than to vasculitic infarction. We concluded that cerebral psychosis was a relatively rare presentation in our patients with SLE. In patients who presented with a neurological problem, especially mental confusion, efforts should be made to ascertain the underlying cause, especially if this may be an infection.

Headaches, vomiting and altered sensorium can be seen in patients with migraines as well as in patients with shunt malfunctions. This is a report of 10 patients with hydrocephalus and CSF shunts who presented with headache, vomiting, varying degrees of impairment of consciousness, and coma. Various diagnostic considerations were made: shunt malfunction, slit ventricle syndrome and low pressure (overshunting). Repeated operative procedures were performed in all. 7 of 10 patients had a family history of migraines when the diagnosis of migraine was entertained, 8 patients improved on propranolol therapy, 1 failed with this therapy but responded to verapamil. In the remaining 2 patients, after a transient response to propranolol, compartmentalized hydrocephalus became obvious and improvement followed with shunt procedures. It is concluded that in those patients with hydrocephalus and small ventricles on neuroimaging and a family history of migraines, and in the face of documented adequate shunt function, the diagnosis of migraines be entertained before further operative interventions.

A case of fungal aneurysm associated with presumed Tolosa-Hunt syndrome is reported. A 57-year-old man was admitted to our hospital with complaints of left blepharoptosis, headache and weight loss. Neurological examination revealed left ophthalmoplegia without facial hypesthesia. Visual acuity was normal. Laboratory studies showed raised ESR, 4+ glycosuria, and a blood sugar of 351mg/dl. Computerized tomography (CT) scan and left carotid angiography were considered normal. Left orbital venography showed no filling of the left cavernous sinus. Diabetic ophthalmoplegia was suspected by a neurologist. The patient was treated with insulin therapy, but visual acuity worsened, and hypesthesia was noted in the first and second divisions of the left trigeminal nerve. Subsequent CT scan demonstrated a high density lesion, which was homogeneously enhanced, in the left cavernous portion and the superior orbital fissure. The patient was presumed of Tolosa-Hunt syndrome, and prednine therapy (30mg/day) was started. On the second day after the administration of prednine, hypesthesia of the first and second division of the left trigeminal nerve improved. After 9 days of prednine therapy, the patient suddenly complained of severe headache, and lapsed into a coma. Massive hemorrhage with subarachnoid hemorrhage was recognized on the CT scan, with a marked midline shift to the right. The hematoma was immediately removed. A ruptured cerebral aneurysm was found at the bottom of the hematoma. The aneurysm was located in the distal portion of the left middle cerebral artery. Aneurysm clipping with external decompression and bilateral ventricular drainage was performed.(ABSTRACT TRUNCATED AT 250 WORDS)

We review the 257 patients hospitalized for meningitis in the Cantonal University Hospital, Geneva between 1st January 1980 and 31st December 1986. 104 patients had acute bacterial meningitis (32 Str. pneumoniae, 21 N. meningitidis, 10 Listeria monocytogenes, 8 streptococci, 5 H. influenzae, 5 staphylococci, 4 gram negative bacilli and 19 without identified bacteria), 124 patients had viral meningitis and 29 meningitis of other etiologies (6 tuberculous meningitis, 2 fungal meningitis, 1 leptospiral meningitis, 5 neoplastic meningitis--one already counted because of a meningitis due to Staph. epidermidis--2 meningitis consecutive to a meningeal irritation, 4 already treated meningitis of undetermined etiology, 2 chronic meningitis and 8 meningoencephalitis). The total mortality was 14.4%. It was zero in viral meningitis and 28% in bacterial meningitis (47% in cases of Str. pneumoniae, 5% in cases of N. meningitidis, 20% in cases of Listeria monocytogenes, 38% in cases of streptococci, 0% in cases of H. influenzae, 60% in cases of staphylococci, 50% in cases of gram negative bacilli, 16% in cases of unidentified bacteria). The striking difference in mortality emphasizes the importance of recognizing a bacterial etiology in order to institute antibiotic therapy as soon as possible. The delay between admission and lumbar puncture averaged 15 hours (range 0.25-96 h) in patients with acute bacterial meningitis and 6.3 hours (0.5-80 h) in patients with viral meningitis. The delay between admission and institution of the antibiotics averaged 5.3 hours (1-48 h) in cases of acute bacterial meningitis and 4.8 hours (0.5-48 h) in cases of viral meningitis. A better clinical workup may provide a reliable diagnosis sooner. In the collective with bacterial and viral meningitis headaches, fever or nuchal rigidity were present in over 80% of the cases. The following features were significantly associated with a bacterial etiology: age over 30 years, alcoholism, concomitant neoplasm, cough, coma, pulmonary rales, new neurological signs or petechia. At least one of these 4 latter signs was present in more than 70% of the cases with acute bacterial meningitis compared to 6% in cases of viral meningitis. Thus the clinical presentation alone serves to recognize the meningitis and to differentiate between a bacterial or viral etiology, thus permitting an immediate therapeutic decision without waiting for complementary investigations. The 104 patients with acute bacterial meningitis were treated with antibiotics: 60 with penicillin, 17 with ampicillin and 26 with other antibiotics; one case did not receive antibiotics. More than the half of the cases with viral meningitis have got antibiotics (52%).
