The existing studies have largely pivoted on various domain-relevant algorithmic approaches to agnize the brain disorders in relevance to malignancy and benign characteristics of an observed tumor. While the previous research pivoted on unimodal approaches such as either image processing or signal analysis...
摘要: We report a case of a schwannoma within the brain stem, apparently only the fourth such case to have been reported.关键词:SCHWANNOMA BRAIN STEM TUMOR MEDULLA-OBLONGATA DOI: 10.3109/02688699309103500 被引量: 20 年份: 1993 收藏 引用 批量引用 报错 分享 ...
Although schwannomas do not spread, they can grow large enough to press down on important structures in the brain (including the brain stem).A very small percentage of nerve sheath tumors are malignant. Is schwannoma a sarcoma? This type of tumor is usuallybenign. Schwannomas are sometimes cal...
The present case, an incidental finding at autopsy, is the third case of schwannoma of the trochlear nerve and the first to illustrate the morphological relationship between this tumor and nerve. Reported cases of schwannoma of the oculomotor and trochlear nerves are summarized in a table. 关键词...
The operative approach and difficulty of resection is highly dependent on the location of the tumor along the trigeminal nerve. Jefferson’s classification proposed in 1959, which categorized the tumor based on the segment of the nerve affected. The Jefferson classification schema categorizes tumors ...

in other words, it is possible to preserve hearing in small tumors confined to the internal auditory canal, but very unlikely to preserve hearing in large tumors that are growing towards the brain. Or to put this in another way, if there is not that much tumor to take out, it is more...
expression was definite in the family vestibular schwannoma,but not very clear in the sporadic one.The inactivating of neurofibromatosis type 2 gene plays a role in the early stage of tumor;maybe there are other genes accounting for the regulation of the tumor differentiation.A further study is ...
The maximum dose to brain stem was 12.9 Gy. The target volume of 19.1 cc received a marginal dose of 10.5 Gy normalized to 80% isodose line. Serial follow-up MRIs showed initial increase in tumor size (pseudo-progression) and marked loss of central tumor contrast enhancement, followed by ...
