objective to study mri diagnostic value on multiple sclerosis.methods mri examination data of 31 patients with multiple sclerosis were analysised retrospectively.results total 184 lesions were detectived in 31 patients.most lesions were located on white watter area beside the lateral ventricle,and a few lesions were located on the spinal cord,cerebellum,brain stem and corpus callosum.the shape of lesion can be circle or ellipse.the lesion showed as slightly long t1 and long t2 signal.the acute stage lesions can have enhancement.conclusions ms have characteristic findings on mri image.mri can show the patholoic changes,and provide strong evidence for clinic diagnosis of multiple sclerosis.

摘 要］目的：探讨多发性硬化（muliplle sclerosis，ms）的mri特征表现及其诊断价值。方法：回顾分析31例临床诊断为ms患者的mri检查资料。结果：31例共发现病灶184个，病灶于侧脑室旁白质区、半卵圆中心及皮层下区最多见，其次见于脊髓小脑、脑干及胼胝体，部分可见视神经受累，病灶呈卵圆形或圆形稍长t1、长t2信号，矢状位像见病灶与侧脑室垂直，急性病灶增强扫描有的可呈结节状、环状或斑点状强化。结论：在mri图像上ms有特征性表现，mri能反应ms病理变化，为临床诊断ms提供可靠依据。

In 1993. We described a 57-year-old female, with a long-standing history of rheumatoid arthritis, presenting with symmetric violaceous to erythematous indurated papules and nodules on her buttock and medial thighs arranging in an arciform fashion for more than three months.

我们在此提出一个长期罹患风湿性关节炎的五十七岁女性，在其臀部与大腿内侧出现对称性的紫红色浸润性丘疹与结节约三个多月。

This is the first reported case of PAN due to hepatitis C with early findings of choroidal and optic nerve infarction.

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。

Figure 2. A, Parasagittal scan at right adnexa shows loculated fluid with several septations with echogenic nodular masses representing peritoneal thickening or omental thickening. B, Transvaginal scan of the left adnexa shows a poorly defined complex mass representing peritoneal or omental thickening.

图2 A，右侧附件区的矢状旁面扫描显示积液呈多房性，有数个分隔，结节性肿块表明腹膜增厚或网膜增厚。B，经阴道扫描显示左侧附件区边界模糊的混合性肿块，表示腹膜或网膜增厚。

The following MRI findings were reliable features in diagnosing endometriosis cyst:（1） High and mixed signal were predominant on both T1WI and T2WI;（2）"Satellite loculi" were visible at the periphery of large cysts;（3）Adhesion to neighboring organs;（4）Assocaled with endometriosis multinodules in pelvic cavity.

以下MRI征象应为卵巢子宫内膜异位囊肿较可靠诊断依据：（1）囊肿在 T1WI和T2WI均为高信号，或以高中信号为主的混杂信号；（2）大囊外有&卫星囊&；（3）边界不清，与临近器官有粘连；（4）盆腔内同时有多发散在不规则形态的内膜异位小结节。

Results It included cysticerci meningitis often seen in the high incidence area of cycticercosis; subacute or chronical onset; recurrent headache, fever, dementia or dizziness, and less meningeal irritation; lymphocyte and mild to moderate protein and positve cysticerci antigen in CSF;cysticerci confirmed in the examination of subcutaneous noduses.

结果 患者生活在囊虫高发地区，多慢性或亚急性起病，表现为反复发作性头痛、发热、头晕或痴呆，脑膜刺激征少见，CSF以淋巴细胞为主，蛋白可升高，囊虫抗体阳性，皮下结节活检被证实为囊虫，囊虫病的典型影像学表现。

If the fontanelle and head circumference were large, and parietal bone amount outstanding on both sides of the nodule, exercise and mental development will not lag behind, with hyperhidrosis, or startle, is suffering from rickets.

如果囟门和头围都偏大，额部和顶骨两侧有突出的结节，运动和智力发育不落后，伴有多汗或惊跳，是患了佝偻病。1岁半囟门不闭合应考虑佝偻病、脑积水、呆小病等。
