    Notes: Summary An 11-year-old boy, treated for acute lymphatic leukemia at the age of 2 with intrathecal injections of Methotrexate, presented with a two year history of pain and signs of lumbo-sacral lesion. MRI, myelography and myelo-CT demonstrated an intradural L4-L5 epidermoid tumor which was removed. Iatrogenic implantation of epithelial cells at the age of two with lumbar punctures is most likely. Decline in incidence of lumbar iatrogenic epidermoid cysts, now an exceedingly rare event, is probably related to improved needles for lumbar punctures.

    Notes: Summary Brain magnetic resonance imaging (MRI), multimodality evoked potentials (EPs) and cerebrospinal fluid examination were performed in 42 patients with myelopathy of undetermined aetiology in order to detect abnormalities usually related to multiple sclerosis (MS). Patients were divided into three groups: insidious-onset myelopathy with only motor signs (group A; 11 patients), with both motor and sensory signs (group B; 18 patients) and acute-onset myelopathy (group C; 13 patients). Multiple brain MRI lesions were found in 18 patients (2 of group A, 13 of group B and 3 of group C). Another 7 patients had a single white-matter lesion. Visual EPs were abnormal in 21 and brain-stem auditory EPs in 12 patients. Paraclinical tests supported the diagnosis of MS in 25 patients (60%) by showing subclinical brain abnormalities. Oligoclonal bands were found in 16 of these 25 patients. The findings strongly suggest a diagnosis of MS in the patients of group B.

    Description / Table of Contents: Zusammenfassung Bei elf Patienten, bei welchen eine olivopontocerebelläre Atrophie mit autosomal dominanter Übertragung angenommen wurde, führten wir eine elektromyographische Untersuchung und eine Bestimmung der motorischen und sensiblen Erregungsleitungsgeschwindigkeit durch. Bei acht dieser Patienten wurde eine Mitbeteiligung des peripheren Nervensystems nachgewiesen. In zwei Fällen mit frühem Krankheitsbeginn wiesen die elektrophysiologischen Veränderungen eindeutig auf eine schwere axonale Degeneration hin, während bei sechs die Befunde mit einer leichten Demyelinisation vereinbar waren.
    Notes: Summary Electromyographic examination and studies of motor and sensory conduction velocities were performed in 11 patients with a presumptive diagnosis of olivopontocerebellar atrophy with autosomal dominant transmission. Peripheral nervous system involvement was shown in eight. In two patients with early onset of disease, electrophysiological alterations clearly pointed to severe axonal degeneration, whereas in six they were compatible with slight demyelination.

    Description / Table of Contents: Sommario 101 Pazienti affetti da Sclerosi Multipla (SM) (53 definiti, 22 probabili, 8 possibili e 18 sospetti secondo i criteri diagnostici di McDonald e Halliday) sono stati studiati con Risonanza Magnetica Nucleare (RMN) allo scopo di valutarne la sensibilità diagnostica in confronto ad altre metodiche diagnostiche quali l'esame del liquor cerebrospinale e lo studio dei potenziali evocati uditivi (ABR). Sono state inoltre valutate le correlazioni tra gravità degli aspetti RMN e parametri clinici (durata, grado di invalidità e tasso di progressione della malattia), e alterazioni delle immunoglobuline liquorali. Aree multiple di demielinizzazione venivano rilevate alla RMN nel 96% delle S.M. definite, nel 77% delle probabili, nel 50% delle possibili e nel 56% delle sospette. Negli stessi gruppi di pazienti l'esame del liquor cerebrospinale risultava positivo per la presenza di bande oligoclonali nell'85%, 68%, 50%, 80% e 28% rispettivamente. La gravità del quadro RMN si correla alla disabilità ed alla durata della malattia, ma non con il tasso di progressione. Le alterazioni delle immunoglobuline liquorali (presenza di bande oligoclonai o elevazione dell'indice IgG) è associata ad una maggiore estensione delle lesioni della sostanza bianca rilevate alla RMN.
    Notes: Abstract 101 patients with multiple sclerosis (MS) (53 definite, 22 probable, 8 possible and 18 suspected according to the McDonald and Halliday criteria) were investigated by magnetic resonance imaging (MRI), to evaluate its diagnostic sensitivity compared to other diagnostic parameters such as cerebrospinal fluid (CSF) findings and auditory brainstem responses (ABR). In addition, correlations between severity of lesions on MRI and clinical data (disability duration of the disease and progression rate) and CSF immunoglobulin abnormalities were evaluated. MRI detected multiple demyelinating lesions in 96% of definite, 77% of probable, 50% of possible and 56% of suspected MS. In the same groups CSF was positive for oligoclonal banding in 85%, 68%, 50% and 37% and ABR in 82%, 50%, 80% and 28% respectively. Severity of MRI was found to correlate with disability and duration of the disease, but not with progression rate. The presence of CSF oligoclonal bands and a raised and IgG index were usually associated with more extensive white matter involvement as evaluated by MRI.

    Description / Table of Contents: Sommario È stata fatta una revisione di tumori del pavimento della fossa media, operati all'Istituto Neurologico “C. Besta” di Milano e verificati istologicamente. I tumor primitivi più frequenti sono i meningiomi e i neurinomi del Vo nervo cranico. Le lesioni maligne sono piuttosto rare; tra queste più comuni le metastasi. Tra i tumori benigni vi sono gli epidermoidi, i cordomi e i condromi. Questi tumori sono stati esaminati e confrontati fra loro dal punto di vista angiografico, tomodensitometrico e radiografico convenzionale con particolare attenzione a problemi di diagnosi differenziale.
    Notes: Abstract Tumors involving or arising from the floor of the middle fossa in cases seen at the Neurological Institute C. Besta were reviewed, and the radiological findings of plain films, angiographic and CT studies are described. Meningiomas, metastases, trigeminal neurinomas, epidermoids, chordomas and chondromas were included in the study.
