RESUMEN
We report the case of a 23-year-old male patient who suddenly developed right hemiparesis, cerebellar ataxia, dysarthria, and bilateral dysmetria. Brain magnetic resonance (MR) examination demonstrated hyperacute ischaemic lesions within the pons. CSF analysis revealed a high protein content, lymphocytic pleocytosis, and oligoclonal IgG bands not present in the serum. Elevated IgM and IgG anti-Borrelia burgdorferi antibodies were shown in both serum and CSF samples, associated with an intrathecal synthesis of these antibodies. Ischaemic CNS lesions have been rarely observed as the first manifestation of Lyme neuroborreliosis. The putative mechanism for parenchymal ischaemia is the local extension of inflammatory changes from meninges to the wall of penetrating arterioles.

A double-blind clinical trial of mitoxantrone versus methylprednisolone was performed in 49 patients with relapsing, secondary multiple sclerosis. Patients were randomized to receive 13 infusions of mitoxantrone 12 mg/m2 (n = 28), or 13 infusions of 1 g of methylprednisolone (n = 21), over 32 months. Twenty-four patients completed the trial. There were no statistical differences between the two groups of patients at study entry. A significant improvement in the Expanded Disability Scale Score (EDSS) was observed in the mitoxantrone group after one year of treatment (p < 0.0022). The total number of relapses, the mean number of relapses/patient/year, and the total number of gadolinium-enhanced lesions on bi-annual MRI scans were significantly decreased in the mitoxantrone group throughout the study period. Nausea, vomiting, and alopecia were more frequent in the mitoxantrone-treated patients. Mitoxantrone has a role in the treatment of MS patients with frequent exacerbations and rapid disease progression.

Pregnancy-specific beta 1 glycoprotein (SP1) was assayed by Particle Counting Assay in the cerebrospinal fluid (CSF) from 26 non-neurological patients, from 190 patients with various neurological disorders and from 84 patients with malignant hemopathies. With a sensitivity limit of 0.5 microgram/l, SP1 was undetectable in normal CSF. High levels were observed in CSF from one pregnant woman with herpetic encephalitis and from another woman with post-puerperal thrombophlebitis as a result of high serum concentrations and leakage of the blood-brain barrier. SP1 was detected at low levels in the CSF from 1 patient out of 5 with Creutzfeldt-Jakob disease and from a patient with Behçet's disease. Seven patients out of 84 with malignant hemopathies presented cerebral involvement; 3 of them had detectable SP1. However, SP1 was also detected in the CSF of 2 patients in apparently complete remission. The determination of SP1 in CSF appears to be of limited value in the diagnosis of neurological disorders and in the early detection of a cerebral localization of malignant hemopathies.

A 30-year-old, previously healthy, non-addicted man presented with a chronic spinal meningitis complicated by arachnoiditis and spinal cord compression. Biopsy showed a chronic granulomatous leptomeningitis, in which some cells contained branching septate organisms that were immunostained with an antiserum to Aspergillus fumigatus. Precipitins to A. fumigatus were detected in cerebrospinal fluid (CSF), but not in blood, and aspergillus infection was apparently restricted to the leptomeninges. Clinically successful treatment led to the disappearance of CSF precipitins and oligoclonal bands.
