Neurologic manifestations, afflicting up to 70% of SLE patients, include psychosis, seizures, chorea, neuropathies, and stroke. MRI is useful in evaluation of lupus patients and several reports have documented cerebral atrophy or focal hyperintensities. We report an unusual MRI appearance in a 56-year-old woman with SLE, diagnosed on the basis of pleuritis, lymphopenia, anti-DNA antibodies, and neurologic involvement. She reported recent onset of Raynaud's phenomenon and generalized macular rash. She presented after two months of gradual deterioration with memory loss, flattened affect, dysphagia, dysarthria, anomia, and somnolence, without focal neurologic signs. Investigations included elevated ESR, reduced complement, normal CSF without oligoclonal bands, negative viral serology, normal hormone and vitamin levels, normal renal and hepatic function. Neuropsychologic testing showed widespread impairment (WAIS-R: FSIQ-63; WMS-69; DRS-98; RCPM-14; WAB AQ-78.8). CT was normal but MRI showed strikingly symmetric, confluent hyperintensities extensively involving cerebral and cerebellar white matter on T1 and T2 weighted scans. Basal ganglia and subependymal and subcortical white matter were spared. Treated with prednisone, the patient made a gradual, but incomplete, recovery. These MRI findings may reflect widespread vasculopathy or direct immunologic brain insult with or without immunologic blood-brain barrier disruption.

We describe 5 patients with a relapsing encephalopathy in association with Hashimoto's disease and high titers of anti-thyroid antibodies. The presentation is usually with a subacute onset of confusion, alteration in conscious level, and focal or generalized seizures. The relapsing course, association with myoclonus or tremulousness, and episodes of stroke-like deterioration are characteristic features. The long-term prognosis is favorable with steroid therapy, though additional immunosuppressive therapy may be required. Neurologic investigation typically shows a diffusely abnormal EEG, high CSF protein level without pleocytosis, and normal brain CT and cerebral angiogram. Isotope brain scan may show patchy abnormal uptake. Hashimoto's encephalopathy should be recognized as a definite neurologic entity and added to the list of CNS complications of thyroid disease.

A 32-year-old primigravida showed signs of pre-eclampsia before delivery of a healthy boy at term. The CSF-space was accidentally punctured during epidural anaesthesia in labour. One day later hypertension was noted and the patient had a single generalized fit. For the next three weeks she had postural headaches, fluctuating hypertension, intermittent hearing loss and double-vision. On the 22nd day of postpartum, the patient had the first of a series of partial and later generalized seizures, followed by hemiparesis, alteration of consciousness, and finally slow recovery with corticosteroid therapy. Bilateral subdural effusions and generalized meningeal thickening were found on MR scans. Repeated MRI excluded sinus thrombosis and documented the response to treatment.

Sixty-one infants aged 0 to 12 months with documented purulent meningitis underwent transfontanellar ultrasonography at the Yaounde Central Hospital. Twenty-eight (45.90%) infants had evidence of complications including communicating hydrocephalus (20 patients; 71.43%), ventriculitis (5; 17.86%), abscess with ventriculitis (2; 7.14%), and cerebral atrophy (1; 3.57%). An analysis of the main epidemiological, bacteriological and clinical parameters found no correlation between the presence of ultrasound evidence of complications and age, sex, or color of the CSF. Conversely, a close correlation was found with both the time elapsed between onset and initiation of treatment and the severity of clinical manifestations (coma, seizures). The authors, recommend routine ultrasound encephalography in infants with meningitis, improved information of parents, and close collaboration between pediatric radiologists and neurosurgeons.

We reviewed 63 cases of cytologically confirmed leptomeningeal metastases (LM). 31 (49%) had solid tumors 17 (27%) had leukemia and 15 (24%) had lymphoma. The most common presenting symptom was pain (76%) with radicular discomfort (58%), headache (32%), neck or back pain (17%). The predominant neurological signs were mental status abnormalities (49%), weakness (47%), seizures (14%). The mode of presentation varied with tumor type. Patients with leukemia (18%) and lymphoma (13%) tended to present frequently with LM without systemic involvement, or during periods of apparent remission (leukemia 35%, lymphoma 27%), while patients with solid tumors had established systemic metastases (90%) at time of presentation. Laboratory studies did not vary among the groups. 71% had positive cytology on the first lumbar puncture (LP) and only 8% required more than 2 LPs. The cell count was a poor predictor of positive cytology as 29% of LP's with positive cytology and 36% of all LP's had less than 4 cells/mm. We conclude that 1) LM presents with pain and seizures more frequently than has been previously recognized; 2) LM is frequently the mode of presentation in patients with leukemia and lymphoma and; 3) cytology is positive frequently in CSF specimens with normal cell counts and chemistries.

We describe an AIDS patient who had a recurrence of Pseudomonas meningitis to illustrate three points. First, the use of sulfamethoxazole-trimethoprim in AIDS patients for prophylaxis of Pneumocystis carinii pneumonia may cause the various body sites to be colonized with resistant species such as P aeruginosa. Second, Pseudomonas meningitis can recur in a patient with AIDS after a month of appropriate therapy. Finally, imipenem is a poor choice for Pseudomonas meningitis, even when alternative therapies appear much less attractive. High doses of imipenem should not be used for fear of seizures, and lower doses only produce resistant organisms in the CSF.

The contents of L-EK, M-EK and beta-EP in CSF of 32 epileptics and 24 controls were determined by RIA. The mean L-EK content of epileptics was significantly higher than that of the controls (P less than 0.01). There were no obvious changes with respect to mean M-EK and beta-EP contents. No significant differences were seen in L-EK contents between generalized and partial seizures, treated and untreated with antiepileptic drugs, normal and abnormal CT manifestation patient groups. These data indicated that endogenous L-EK content was related to human epilepsy, and changes in opioid peptides were selective changes shared by different types of seizures. The increase of L-EK content was not caused by taking antiepileptic drugs, nor due to structural pathological changes of the brain that might be found on CT scanning, but a manifestation of neurochemical disorders of the brain that resulted in epilepsy.

Multiple sclerosis lesions may occur predominantly in the hemispheric white matter and cause various psychiatric disorders such as remitting-relapsing endoform or exogenous psychosis, organic personality alterations and dementia. Nineteen patients suffering from this encephalitic form of multiple sclerosis as diagnosed by characteristic CSF immunoglobulin findings are analysed according to established psychopathological criteria. All cases began with psychiatric symptoms and neurological signs were either absent or overlooked. Several patients developed typical encephalomyelitic symptoms in successive relapses, but other remained with psychiatric disorders over many years. Only four patients had retrobulbar neuritis, but seven suffered from epileptic seizures. The humoral immune response was characterized by a strong dominance of IgG and a local synthesis of polyspecific antibodies against measles, rubella and varicella/zoster virus. The mononuclear CSF pleocytosis was comparatively marked with cell counts up to 180/microliter.

Encephalites with viral replication are due to multiplication of a virus within the central nervous system. Diagnosis and initial therapeutic decisions rest on simple clinical and paraclinical findings: age of the child, presence of high-grade fever, presence and localization of seizures, CSF characteristics, and EEG findings. Acyclovir is always indicated in a drowsy child with a high fever who has even a brief seizure and CSF abnormalities.

In extracerebral systemic lupus erythematosus (SLE), the complement system plays a prominent pathogenic role, and decreased serum concentration of the 4th component (C4) is a reliable indicator of systemic disease activity. In diffuse CNS-SLE, however, the pathogenic role of complement is less clear. In 12 patients with active diffuse CNS-SLE presenting with delirium (4), organic personality syndrome (3), or generalized seizures (5), we determined the CSF indexes of the complement components C3, C4, and factor B, and of IgG, IgA, and IgM. There was a significant increase of the C4 index in these patients compared with controls and a significantly higher CSF C4 index in patients with an increased IgM index. We conclude that intrathecal C4 is being produced in diffuse CNS-SLE.
