Benign meningiomas are less likely to recur than the atypical and malignant types. Atypical meningiomas have a faster growth rate than benign meningiomas, and malignant meningiomas grow the fastest. It is also possible, but rare, to have more than one meningioma at a time. Meningothelial ...
The current systematic review aimed to investigate the meningioma model types used, perform a meta-analysis on tumor take rate (TTR), and perform critical appraisal of the included studies. The study also aimed to assess reproducibility, reliability, means of validation and verification of models, ...
a, Fraction of meningioma samples (n = 200) classified meningioma single-cell types across DNA methylation groups, based on single-cell reference transcriptomes. Lines represent means, boxes represent inner quartile ranges, and error bars represent 10th-90th percentiles (ANOVA, one sided). b,...
Our study confirmed that only edema (P = 0.005) and heterogeneity (P = 0.014) had a significant association with malignant histological types. Other signs were not statistically different among WHO histology types (p > 0.05). On the subject of tumor location, atypical/malignant meningioma was si...
Eighty-three patients with intracranial meningioma were retrospectively analyzed with regard to age, sex, anatomic location, mode of presentation and surgical outcome.The ages of the patients ranged from 11 to 77 years. Fifty-five (66%) were females and 28 (34%) were males. The peak incidence...
Most meningiomas are fixed to the DURA MATER and are benign but, because of their location and the bony surroundings of the nervous system, may do serious damage by compression of neurological structures. Treatment is by surgical removal and this is often successful. Collins Dictionary of Medicine...
The location of intratumoral hemorrhage, cystic changes inside or outside of the tumor mass, calcifications, invasion of the parenchyma by malignant meningiomas, and lobulated or multilobulated masses is demonstrable only with intraoperative ultrasonography. Meningiomas can be identified incidentally on bone...
We analyzed the immune cells of four paired meningioma and non-tumor-associated dura samples composed of 12,581 cells and used the same markers described above to identify cell types. Within each cell type, we observed clear differences in cell state between cells isolated from each location (...
Meningiomas have been divided into three types based on their patterns of growth. Histological factors that increase the grade include a high number of mitotic figures, necrosis and local invasion. Treatment of sphenoid wing meningiomas often depends on the location and size of the tumor. Gamma ...
Meningiomas are slow-growing tumors. Surgery may be suggested based on size and location. "Most meningiomas are benign, and aftersurgery, they may never regrow. Or if they do, it may take a very long time," she says. Glioblastoma Another type of brain tumor is cancerous and fast-growing....
