Abstract Meningiomas account for more than 30% of all intracranial brain tumors, with 25% of them originating somewhere along the skull base and about 20% of these located in the posterior fossa. The intimate relation of these tumors with neural and vascular structures make them difficult to treat, both surgically and nonsurgically. Their treatment is further hampered by the lack of definitive recommendations, which is partially due to the fact that there is no general accepted model of classification. The present report proposes a new concept of classification of posterior fossa skull base meningiomas, one that takes into account the intimate relation of these tumors with arachnoid structures, simplifies the overcrowded landscape of their systematization and can be extended to oher skull base locations.

Isotope Cisternography

SummaryThe cerebrospinal fluid (CSF) circulation was studied with isotope cisternography in 30 patients with a schizophrenic type of psychosis. All had previously received neuroleptic treatment. Disturbed CSF circulation was found in 10 cases. In four of these, persistent intraventricular radioactivity was observed as well as partly obstructed CSF spaces. In the other six cases a slow CSF circulation was noted as well as evidence of partly obstructed CSF spaces especially of the upper posterior frontal region. Signs of atrophy of the cortex and vermis were found on CT scan in 10 cases. In four of these subjects a local atrophy was noticed in the upper posterior frontal cortex and around the frontal part of the interhemispheric fissure. Seventeen of the patients (57 per cent) had pathological findings at isotope cisternography and/or at CT. Disturbed circulation did not correlate with CT-findings, age, duration of psychosis, alcohol abuse, drug consumption or family history for psychosis. CT evidence of brain atrophy was significantly related to nonfamilial type of psychosis.

✓ Review of more than 1400 positive-contrast myelograms of the posterior fossa performed at the Mayo Clinic indicates that this is an excellent method for depicting normal and pathological anatomy in the basal cisterns, if an adequate amount of medium and a precise technique are used. However, the technique is not without its sources of diagnostic error and these are discussed.

Abstract Background Traumatic posterior fossa hematoma is a rare entity. Traumatic posterior fossa hematomas are associated with considerable morbidity and mortality and their surgical management remained controversial. Methods From August 2011 to August 2017, approximately 5,100 patients with head injury were managed. Authors reviewed clinical and radiological findings, management criteria, and outcome of posterior fossa hematoma in 21 patients. Results Out of 21 cases, 13 survived with our management. The Glasgow Coma Scale (GCS) on admission was higher in favorable group than in poor outcome group. Factors associated with Glasgow Outcome Scale in two groups were status of fourth ventricle, basal cisterns, subarachnoid hemorrhage (SAH), hematoma volume, and their location (hemispheric or midline). Similarly, associated supratentorial lesions, age, gender, lesions in other parts of body, and timing from injury to reporting to hospital were taken into consideration. Conclusion The factors correlated with patient outcome were age, sex, mode of injury, GCS at admission, associated intracranial hematomas, associated SAH, hematoma volume, hematoma location, basal cisterns, status of fourth ventricle, and associated multiple injuries on other body parts. It is hereby concluded that timely surgical intervention should be employed whenever indicated without delay. Posterior fossa hematomas were rarely observed in the pediatric age group.

In the course of several 21-cm observing programmes being carried out by the Leiden Observatory with the 25-meter telescope at Dwingeloo, a fairly complete, though inhomogeneous, survey of the regionl11= 0° to 66° at low galactic latitudes is becoming available. The essential data on this survey are presented in Table 1. Oort (1967) has given a preliminary report on the first and third investigations. The third is discussed briefly by Kerr in his introductory lecture on the galactic centre region (Paper 42). Burton (1966) has published provisional results of the fifth investigation, and I have discussed the sixth in Paper 19. All of the observations listed in the table have been completed, but we plan to extend investigation 3 to a much finer grid of positions.
