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。

Results Among the 52 cases, 30 cases were confirmed to fibrosarcomas, which were identical with primary dingnoses;22 cases were revised to malignant fibrous histocytoma (8 cases), malignant nerve sheath tumor (4 cases), monophasic spindle cell synovial sarcoma (3 cases), leiomyosarcoma(3 cases), rhabdomyosarcoma(2 cases) and abdominal desmmoid tumor (2 cases). Of the 18 cases, only two cases were misdiagnosed and were revised to malignant fibrous histocytoma and spindle cell synovial sarcoma, respectively.

结果：1980年前52例中维持原诊断30例，修改诊断22例(42.3%)，分别为恶性纤维组织细胞瘤8例、恶性神经鞘膜瘤4例、单相性梭形细胞滑膜肉瘤3例、平滑肌肉瘤3例、横纹肌肉瘤2例、韧带状纤维瘤2例；1980年后纤维肉瘤18例中，维持原诊断16例，修改诊断2例(11.1%)，分别为恶性纤维组织细胞瘤和滑膜肉瘤各1例。

Methods: The clinical materials of different pathological types of intraspinal tumors including neurinoma, meningioma,glioma, angioma and lipoma were comprehensively studied on 77 patients.

系统分析了77例原发性椎管内肿瘤，包括神经鞘膜瘤、脊膜瘤、胶质瘤、血管瘤和脂肪瘤等几种不同病理类型肿瘤的临床资料。

Interphone began by gathering a group of people who had had the cancers of interest (glioma, meningioma, acoustic neurinoma and parotid gland tumour) and questioning them about their past use of mobile phones.

Interphone的研究始自汇聚一组曾经有过某种特定癌症（神经胶质瘤，脑膜瘤，听觉神经炎和腮腺肿瘤）并问他们一些有关曾经使用手机的经历。

Methods Twenty-four cases with non-pituitary lesions in sphenoidal sinus and sellar area were analyzed . Eighteen cases were benign, including 7 sphenoidal sinus cyst, 6 craniopharyngioma, 2 chordoma, 1 nasal polyp extending into the sella,1 neuronoma in sella,and 1 pinealoma.

总结分析24例蝶窦鞍区非垂体源性占位性病变，其中良性18例，包括蝶窦囊肿7例、颅咽管瘤6例、脊索瘤2例，鼻息肉伴鼻硬结杆菌感染侵犯蝶窦鞍区、蝶鞍神经鞘瘤、鞍内异位松果体瘤各1例。

Plexiform schwannoma is a rare variant of the typical schwannoma.

丛状神经鞘瘤是良性神经鞘瘤的罕见变异型。

Results: Among them, 9 cases were neurilemomas and 3 cases were neurofibromas.

结果：在12例外周神经良性肿瘤中，神经鞘瘤9例，神经纤维瘤3例。

Because of the infiltrating features, neurofibromas are more difficult to surgically dissect without damage to the nerve compared with schwannomas.

由于神经纤维瘤具有浸润性，与神经鞘瘤相比在手术切除并且不损伤神经的难度很大。

It provided an optional treatment for patients with small to medium size acoustic neuromas, and an important adjuvant therapy for treating residual and recurrent tumors

无面瘫和面部麻木，听力保留率59I2%结论伽玛刀对听神经瘤有较高的肿瘤控制率，并能保留有用听力，对面神经、三又神经损伤小，是小至中等大小听神经瘤可供选择的治疗方法，及术后残余和复发肿瘤的重要辅助治疗手段。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
