Object. The authors examined the relationships of brain—tumor interfaces, specific magnetic resonance (MR) imaging features, and angiographic findings in meningiomas to predict tumor cleavage and difficulty of resection.Methods. Magnetic resonance imaging studies, angiographic data, operative reports, clinical data, and histopathological findings were examined retrospectively in this series, which included 126 patients with intracranial meningiomas who underwent operations in which microsurgical techniques were used. The authors have identified three kinds of brain—tumor interfaces characterized by various difficulties in microsurgical dissection: smooth type, intermediate type, and invasive type. The signal intensity on T1-weighted MR images was very similar regardless of the type of brain—tumor interface (p > 0.1). However, on T2-weighted images the different interfaces seemed to correlate very precisely with the signal intensity and the amount of peritumoral edema (p < 0.01), allowing the prediction of microsurgical effort required during surgery. On angiographic studies, the pial—cortical arterial supply was seen to participate almost equally with the meningeal—dural arterial supply in vascularizing the tumor in 57.9% of patients. Meningiomas demonstrating hypervascularization on angiography, particularly those fed by the pial—cortical arteries, exhibited significantly more severe edema compared with those supplied only from meningeal arteries (p < 0.01). Indeed, a positive correlation was found between the vascular supply from pial—cortical arteries and the type of cleavage (p < 0.05).Conclusions. In this analysis the authors proved that there is a strong correlation between the amount of peritumoral edema, hyperintensity of the tumor on T2-weighted images, cortical penetration, vascular supply from pial—cortical arteries, and cleavage of the meningioma. Therefore, the consequent difficulty of microsurgical dissection can be predicted preoperatively by analyzing MR imaging and angiographic studies.

Object. The purpose of this study was to examine patterns of diagnosis and relative survival rates in individuals in whom a primary malignant brain tumor was diagnosed between 1973 and 1997; follow-up review of these patients continued through the end of 1999. Methods. The study population was composed of 21,493 patients with primary malignant brain tumors that were diagnosed between 1973 and 1997. Data on these patients were obtained from the population-based Surveillance, Epidemiology, and End Results Program. The study population was divided into three cohorts based on the year of diagnosis, and these groups were compared with respect to variables of interest by performing chi-square tests and relative survival analysis with the life table method. Over time, there were consistently more men, more Caucasians, more patients undergoing surgery, and more individuals 70 years and older who received the diagnosis of primary malignant brain tumor. An examination of proportions of individuals with astrocytoma, other; oligodendroglioma, other; and oligodendroglioma Grade III showed significant temporal changes with frontal and temporal lobe tumors occurring most often. The diagnosis was obtained at an earlier age in African-American than in Caucasian patients. Caucasians had higher proportions of glioblastoma multiforme (GBM), which was associated with decreased survival times, and of oligodendroglioma, other, whereas African Americans had higher proportions of astrocytoma, other; ependymoma Grade II or III; and medulloblastoma, all of which were associated with increased survival times. The relative survival case demonstrated a continuous improvement over time, although older patients, those who underwent biopsy only, and those with GBMs continue to have the poorest survival times. The relative survival rates of African Americans consistently were similar or worse than those of Caucasians when the groups were stratified by prognostic factors. Conclusions. Over time, the relative survival rate of individuals with primary malignant brain tumor has improved and differences in survival are seen by examining the race of the patients.

✓ The authors report the case of a man who had suffered a penetrating metal splinter injury to the left frontal lobe at 18 years of age. Thirty-seven years later the patient developed a left-sided frontal tumor at the precise site of the meningocerebral scar and posttraumatic defect. Histological examination confirmed a glioblastoma multiforme adjacent to the dural scar and metal splinters. In addition, a chronic abscess from which Propionibacterium acnes was isolated was found within the glioma tissue. The temporal and local association of metal splinter injury with chronic abscess, scar formation, and malignant glioma is highly suggestive of a causal relationship between trauma and the development of a malignant brain tumor.

✓ A comparison of intravenous to intracarotid artery (ICA) administration of 14C-BCNU (1,3-bis(2-chloroethyl)-1-nitrosourea) was made in squirrel monkeys. Radioactivity was measured as soluble drug products and as RNA-, DNA-, and protein-bound radioactivity. The ICA administration of BCNU achieved 190% to 280% higher brain nucleic acid-bound drug levels than use of the intravenous route in the infused hemisphere and 130% to 280% higher levels than in the noninfused hemisphere. In addition, some brain regions directly subserved by the middle cerebral artery had bound drug levels four- to fivefold greater than those found in regions of noninfused brain. The data suggest that a need for BCNU dose reduction due to myelotoxicity may be an indication for ICA therapy in selected brain-tumor cases.

✓ This 10-year-old child suffered a hemorrhage into the right parietal lobe, the result of a ruptured arteriovenous angioma. From birth, the boy had a venous angioma of the mucous membrane of the cheek, lower lip, and hypoglossal area on the right side. The coexistence of these two vascular defects is most unusual, and venous angioma in early life may suggest the presence of cerebral angioma.

✓ On November 25, 1884, Mr. Rickman J. Godlee performed the first recognized resection of a primary brain tumor. This operation was carried out at the suggestion of Dr. A. Hughes Bennett, a neurologist at The Hospital for Epilepsy and Paralysis, Regents Park, London, England. Other operations for intracranial tumor had been performed but were for extracerebral meningeal or osseous tumors. The “first” operation for a primary cerebral tumor by Godlee was meticulously described and well documented in the medical and popular press of the day and stimulated both professional and lay discussions of the topic that directly and indirectly led to further surgery on the cerebrum itself and the advent of modern neurosurgery. The original patient of Mr. Godlee died on the 28th postoperative day of apparent meningitis and secondary complications, but postmortem examination revealed no remnant of the excised glioma.

✓ Although cerebral venous malformations have been reported to cause epilepsy, progressive neurological deficits, and hemorrhage, their clinical significance remains controversial. In an attempt to clarify the natural history of the lesion and suggest an appropriate management strategy, the authors review their experience with 30 patients. In four patients with cerebellar venous angioma, an acute episode of ataxia was documented. The coexistence of a cavernous malformation was pathologically confirmed in the two patients who underwent surgery for bleeding presumed caused by the venous angioma. Infarction was shown in two patients and a tumor in two others. Follow-up periods ranged between 18 and 104 months, with only five patients symptomatic at the time of this report. Rebleeding had not occurred, nor had acute episodes of neurological dysfunction been documented. This clinical experience suggests that a venous malformation is frequently associated with other, more symptomatic conditions and is often erroneously identified as the source of the symptoms. Because the nature of the relationship between the venous malformation and the allied conditions remains ambiguous, it is recommended that patients harboring a “symptomatic” venous malformation undergo high-field magnetic resonance imaging to rule out underlying pathology, and that any such pathology be treated independently of the venous malformation.

✓ The authors report an unusual case of an extensive spontaneous subgaleal hematoma caused by a bilateral arteriovenous shunting lesion involving the diploic veins. The enlarged diploic canals and the existence of bilateral diploic arteriovenous shunts with no history of fracture or trauma indicate that these fistulas developed spontaneously over a long period of time. Angiographic findings in these unusual arteriovenous shunting lesions and their endovascular management are briefly illustrated. A case of a bilateral diploic fistula has not been reported before and it may contribute to the understanding of the diversity of dural arteriovenous shunting lesions.
