查询词典 neuromas

About 5% of acoustic neuromas are caused by a rare, inherited condition called neurofibromatosis.

约5 ％的听神经瘤是因一种罕见的遗传性神经纤维瘤病的所谓条件。

Results Of 80 cases 46 were acoustic neuromas (57.5%), 15 meningiomas (18.5%), 6 epidermoid cysts(7.5%), 5 trigeminal neuromas (6.3%) and 8 other rare tumors(10%).

结果 80例肿瘤中，听神经瘤46例(57.5%)，脑膜瘤15例(18.8%)，上皮样囊肿6例(7.5%)，三叉神经瘤5例(6.3%)及其它少见肿瘤8例(10%)。

Results MRI appearances of acoustic neuromas were:（1）The turmor's growth round the internal auditory canal,the Ⅶ,Ⅷ nerves affected side were thickened than that of opposite side.There was no marked demarcation between the main bodies of the tumors and the affected nerves.The connection between tumors and affected nerves could be showed at contrast enhanced imaging.（2）The tumors were of hypo or isohypo intensity on T1 weighted images and hyper or iso hyper intensity on T2 weighted images.（3）After Gd DTPA administration the tumors were homogeneously or inhomogeneously or circularly enhanced.（4）The margins of the tumors were smooth and well delineated.（5）The affected internal auditory canal usually became shorter in depth and larger in posterior anterior diameter.（6）MRI appearances of micro acoustic neuromas were that the affected Ⅶ,Ⅷ nerves were normal in size or nodularly thickened and the tumor reveaed nodular or point enhancement at contrast enhanced MRI.

结果 听神经瘤的MRI表现主要为：（1）肿瘤以内听道为中心生长，第Ⅶ、Ⅷ神经束较对侧增粗，与肿瘤主体多无明确分界，增强后可见两者相连，颇为特征；（2）肿瘤在T1加权图像上呈低信号、略低信号或低等混合信号，T2加权呈高信号或高等混合信号；（3）注射Gd DTPA后肿瘤呈均匀、不均匀或环状强化；（4）肿瘤边界清晰，边缘光整；（5）绝大多数肿瘤患侧内听道前后径扩大，深径缩短；（6）微小听神经瘤的MRI表现为第Ⅶ、Ⅷ神经束正常或局部结状增粗，造影后呈结节状或点状增强。

Objective To summarize the neurosurgical method and experience of cervical neuromas.

目的 总结颈椎管神经源性肿瘤手术治疗的方法与经验。

Lateral tumors in adults often appear extraaxial and may simulate meningiomas of the cerebellopontine angle or tentorium, acoustic neuromas, ependymomas, glomus jugulare tumors or metastases, solid hemangioblastoma and choroid plexus papilloma.

位于外侧的肿瘤经常表现类似于轴位病变，与桥小脑角区或幕下脑膜瘤、听神经瘤、室管膜瘤、颈静脉球瘤或转移瘤、实性血管母、以及脉络膜乳头状瘤相类似。

Objective:To study MRI appearances and characteristics of acoustic neuromas.

目的：研究听神经瘤的MRI表现与特征。

Results In 28 cases ,16 were aconstic neuromas,6 were trigeminal neuromas,3 were meningiomas,3 were cholestcatomas.

结果：听神经瘤16例，三叉神经瘤6例，脑膜瘤3例，表皮样囊肿3例。

MRI is an effective method in detecting acoustic neuromas.Gd DTPA enhancement is very valuable in the diagnosis of microacoustic neuromas.

MRI是检查听神经瘤的有效方法，Gd DTPA对微小听神经瘤的诊断很有价值。

Methods:MRI of 138 acoustic neuromas in 135 cases proved by operation and pathology were analyzed,in which there were 10 small acoustic neuromas,42 cases were Gd-DTPA enhanced.

收集手术和病理证实的135例、138个听神经瘤的MRI，其中微小听神经瘤为10例，行Gd－DTPA增强扫描为42例。

The neuromas presumably arose from small perivascular nerve twigs that have been implicated in the pathogenesis of intramedullary neuromas in non-neoplastic spinal diseases.

神经瘤大概由血管周小神经末梢发展而来，这些神经末梢与髓内神经瘤的发生有一定关系。
