Meningiomas tend to bebroad based, eccentric to the internal auditory canal, and often have adjacent dural enhancement (dural tails). Vestibular schwannomas usually involve and are centered on the internal auditory canal, are more rounded, and rarely have adjacent dural enhancement. What can I expe...
The goal of this study was to examine the cytologic features of meningiomas in CP and evaluate if benign meningioma (Grade 1), atypical meningioma (Grade 2), and malignant meningioma (Grade 3) can be diagnosed on CP. All cases of meningioma (1999-2007), which were submitted for frozen ...
Expression of vascular endothelial growth factor in diffuse malignant pleural mesothelioma Angiogenesis is an important part of normal and pathological processes, including tumour growth, metastasis, inflammation and wound healing. VEGF is the be... JE K?Nig,E Tolnay,T Wiethege,... - 《Archiv Für...
calculated a new parameter, namely SUV/ADC, and showed that it had a great potential in differentiation between malignant and benign breast lesions [17]. According to Kim et al., combined parameters of 18F-FDG-PET/MRI could be effective predictors of tumor treatment failure after head and ...
Atypical and malignant meningiomas: an outcome report of seventeen cases Limited data are available concerning the outcome of patients with atypical and malignant meningiomas. We therefore analyzed the outcome of seventeen patie... CC Coke,BW Corn,M Wernerwasik,... - Journal of Neuro-Oncology 被...
Meningiomas About 25% of spinal cord tumors are this type. They're more common in women than men, and they usually start in middle age or later. They grow in the meninges, the three membranes that cover and protect your brain and spinal cord. Usually they're not cancerous, but the one...
The team reports that the analysis of 365 meningiomas by integrating multiple molecular profiling approaches strongly suggested there are three biologically distinct groups, with one being reliably malignant. This could transformpatient careby providing a better prognosis and revealing the tumors that requir...
Conclusion:Differentiating meningiomas with atypical conventional MRI findings from malignant intraaxial tumors can be difficult. Calculation of rCBV ratios and construction of signal intensity-time curves may contribute to the differentiation of meningiomas from intraaxial tumors....
SpineBackground: Malignant meningiomas are rare neoplasms of the central nervous system that occur de novo or rarely due to transformation. They have a higher rate of recurrence and metastasis accompanied by a significantly shorter survival rate compared to benign variants. Meningioma cancer stem cells...
Nevertheless, several findings such as losses or deletions of chromosomes 22, 11, or 13 in meningiomas, Wilm's tumor, and retinoblastoma respectively (Z ankl and Z ang 1972), and double minute chromosomes in advanced neuroblastoma (B rodeur et al. 1984) have been well established....
