Common origin of the arterial blood flow for an arteriovenous medullar fistula and the anterior spinal artery: a case report.

A common origin of the blood supply to a dural arteriovenous malformation and to the spinal cord from the same segmental artery is very rare. This obviously contraindicates embolization of the fistula. Demonstrating the location of the normal spinal blood supply system is therefore mandatory to avoid postoperative complications. The visualization of the normal blood vessels can be masked by a steal phenomenon, but it must at all costs be obtained. The authors describe one such case.

[Intermediate neurological development of 60 neonates weighing 1500 grams or less at birth. Predictive value of initial findings (clinical aspects, electroencephalograms and brain imaging)].

60 low birthweight (less than or equal to 1,500 g) are distributed according to existence or not, and intensity of brain disturbances, during the neonatal period; appreciated by neurological examinations, early EEG and brain imaging during the second month of life. At 18 months, at least, neurological outcome is normal for 46 children (but 6 had transient neuromotor anomalies), 14 have sequelae (7 mild, 7 major). All children with clinical neurological examination carried out during the neonatal period are normal at follow up. It is true also for the children without EEG anomaly and normal brain imaging. The early prediction of neurological outcome can be made easily with consideration of these three data. Standardised test are proposed, during the neonatal period, for these low birth weight infants.

The place of digital intravenous angiography in cerebral infarcts.

The authors describe their technique of intravenous digital subtraction angiography (IVDSA) and discuss the results in cerebral infarcts. IVDSA is a good first stage examination for the recognition of stenosis or occlusion of cervical vessels to the brain, as it is an only marginally invasive and easy technique. It is, however, good neither for the study of focal cervical not of intracranial areas.

[Dura mater arteriovenous fistula and lateral sinus occlusion].

It is rare to find an arteriovenous fistula of the dura mater associated with a venous sinus occlusion, but this may provide evidence of an etiology. In the case reported, the malformation was probably of congenital origin, the sinus thrombosis having occurred secondarily to the venous stasis adjacent to the fistula.

[Acute neurological deficit in treated malignant hemopathies].

Neurological complications are frequent in the course of malignant hematological diseases. Five cases occurring in children are reported here: 4 presented with acute lymphoblastic leukemia and 1 with lymphoma. The clinical pattern was remarkably acute, with fever, seizures and a neurological deficit. Brain CT scan showed a limited hypodensity sometimes with a contrast uptake in the involved area in the first days or weeks. Seroconversion for measles virus occurred in 3 cases, associated with the presence of helix-like bodies in the cerebrospinal fluid and/or cerebral tissue. These case reports are discussed with respect to the neurological complications already reported in patients with hematologic malignancies. The hypothesis of measles-virus related encephalitis seems likely.

[Lumbar phelbography without catheterization. Technic, indications and results in the diagnosis of intervertebral disk herniation].

The authors present a new method of lumbar phlebology without catheterism by direct venous puncture of the femoral veins. An analysis of 300 contrast tests maked it possible to identify different types of pathological images characterized by disappearance and displacement of epidural veins corresponding as a rule to discal hernia when the uncharacteristic shadowy images do not allow one to make a precise conclusion or to determine whether an operation is needed. With equal reliability (96 percent), lumbar phlebography without catheterism is, by its simplicity and harmlessness and the absence of minor and major venous complications, preferable to phlebography by catheterism. Carried out in all subjects, whatever their age, without special precautions, it seems to us to now be the most desirable test to be used in the radiological investigation of lumbar discal hernias.

The intra-arterial injection of Iskedyl for hyperselective vascular exploration.

The development of spasm with the introduction of catheters into very small calibered arteries has tended to interfere with routine superselective catheterization. To overcome this problem the vasodilating drug Iskedyl, which containes raubasine 6.25 mg and dihydroergosistine 0.3125 mg in an ampule of 2.5 ml, has been injected into the artery being manipulated. The study was conducted on 112 patients undergoing hyperselective explorations of intracranial, thoracic, abdominal and peripheral arteries of small caliber and the results have been most gratifying and encouraging.

[Cervical localization of a primary meningeal melanoblastoma].

The authors present a case of primary meningeal melanoblastoma localized in the cervical region, in a 47 year old woman. The intra and extradural, extramedullary tumor presented clinically and radiologically as a neuroma with central calcification. This case thus widens the possible causes of an intraspinal tumoral syndrome with radiological calcification.

Neurologic disorders due to brain manganese deposition in a jaundiced patient receiving long-term parenteral nutrition.

BACKGROUND: Neurologic and radiologic disorders have been reported in patients receiving long-term parenteral nutrition (PN). On the basis of elevated serum manganese levels, some of these abnormalities have been attributed to manganese intoxication. Alterations of the basal ganglia signal intensity on T1-weighted magnetic resonance images (MRIs) have been previously reported, but the precise nature of these alterations remains controversial although the deposition of manganese has been suggested in patients with chronic hepatic encephalopathy due to liver failure. METHODS: We report the case of a patient who was receiving PN and exhibited a chronic cholestasis. Neurologic disorders appeared after several months of PN, when a hypersignal in the basal ganglia and white matter was found on T1-weighted MRIs of the brain in association with elevated serum and manganese levels. RESULTS: Elevated autopsic concentrations of manganese were found in the radiologic abnormal cerebral areas. CONCLUSIONS: Our observation is the first demonstration of a relationship between high intracerebral manganese levels, radiologic abnormalities, and neurologic disorders during long-term PN. Moreover, serum manganese levels are not a good indicator of cerebral levels. In fact, in our patient, serum manganese levels returned to normal, whereas those of cerebral manganese remained increased.
