Results Of total 8 cases, 4 eases were located in the side of cerebral falx or sinus,2 eases in the convexity of the brain,1 ease in the sphenoidal erest,1 ease in the tentoriam of cerebellum the main findings were as followes: 4 eases were cystic tumores with obvious enhancement in the substant parts; 2 eases were shown as eystoma with the wall knot enhanced obviously; cystic tumores were found in 2 eases with the wreath form enhance; peritumoral edemaarea in 2 ease, hyperostosis were seen in 3 eases.

结果 本组8例囊性脑膜瘤均为良性，肿瘤位于镰旁／窦旁4例，大脑凸面2例，蝶骨嵴1例，小脑幕1例。其主要CT表现有：囊实性肿块，实质部分强化明显，4例；有壁结节的囊性病变，增强时壁结节强化明显，2例；环形强化的囊性肿块2例；瘤周伴水样低密度区2例，邻近骨质增生硬化3例。

Results: MR demonstrated capsule wall and papillary solid lesions in one case with cystic and solid lesions of hepatobiliary cystadenoma. Poly cystic form tan if different sine in sew case, capsule wall and septation was thick, part of capsule wall was obviously thickened and nodes form, intrahepatic bile duct was dilated, large poly-antrum cystic keen form structure in one case, capsule wall and septation were smooth, part of capsule wall was uniformly thicken, capsule wall, septation, mural nodus form and solid lesions in three cases wee all slightly hyperintense on T2WI and slightly hypointense on T1WI. Part of cyst fluid was hypointense on T2WI the diameter if tumor ranged from 3.4cm to 13.5cm. Part of capsule wall, septation, solid lesions and mural nodus west obviously enhanced in arterial phase in three cases, the extent of enhancement showed a little degrade in port vein phase, balance phase and delay phase, but dense to liver parenchyma at synchronization.

结果：3例肝内胆管囊腺瘤中1例呈囊实性结构，可见囊壁及乳头状实性肿块；1例为多个大小不等的多房囊状结构，囊壁及分隔光滑，囊壁局部明显增厚，有壁结节，周围见轻度的肝内胆管扩张；1例为巨大的多房囊状结构，囊壁及分隔光滑，局部均匀增厚；3例中的囊壁、分隔、壁结节及实性部分均呈T2WI稍高信号、T1WI稍低信号，囊内液性部分均呈T2WI高信号、T1WI低信号；肿瘤瘤体大小径线范围3.4~13.5cm.3例肝内胆管囊腺瘤中囊壁、分隔、实性肿块和壁结节动脉期均明显强化，门脉期、平衡期及延迟期强化程度略减低，强化程度均高于同期肝实质。

Multilocular cystadenomas have the typical MRI manifestations and MRI is valuable, whereas unilocular cystadenomas, having similar MRI findings with some other benign cystic lesion, are lack of enough features in MRI. However, thick irregular wall or septa in MRI might be helpful in differential diagnosis.

多房性囊腺瘤具有较典型的MRI表现，诊断不难；单房性囊腺瘤缺乏特异表现，囊壁强化是与其他囊性病变鉴别诊断的重要徵象，MRI检查对诊断有重要作用。

Results Among all 25 cases of lymphangioma,Within 20 cases of cystic lymphangioma,single cyst was showed in 14 cases and multilocular cyst was showed in 6 cases in plain scan,and little enhancement of capsule wall and septal in 8 cases in enhancement scanning. Cystic-solid mass was showed in 4 cases of cavernoma lymphangioma in plain scan,and solid part of mass was enhanced obviously in enhancement scanning.1 capillary ymphangioma showed the skin and hypodermic thicking,and part of area showed little beehive-like feature. Enhancement scanning showed slight irregularity enhancement.

结果 25例淋巴管瘤中20例囊性淋巴管瘤，CT平扫14例表现为单一囊肿，6例表现为多房性囊肿，囊腔内见有分隔；增强扫描8例出现囊壁或间隔的轻微强化。4例海绵状淋巴管瘤平扫均表现为囊实性肿块，增强检查实性部分有明显分期增强；1例毛细管型淋巴管瘤表现为局部皮肤及皮下组织的增厚，部分区域见有小蜂房样表现，增强扫描见有轻度不规则强化。

Methods CT appearances of 10 cases with cystadenoma and cystadenocarcinoma of the pancreas confirmed by clinic and pathology were retrospectively analyzed.

e#［摘要］目的：探讨胰腺囊腺瘤与囊腺癌的CT表现。方法：回顾性分析经手术及病理证实的10例胰腺囊腺瘤与囊腺癌的CT表现，总结其特征性表现。

There hae been a few reported cases of bursal osteochondromatosis inoling the retrocalcaneal, subacromial, and subcoracoid bursae2,10,11; howeer, infrapatellar bursal osteochondromatosis has neer been reported in the English-language literature, to our knowledge.

已报道的粘液囊骨软骨瘤病病例包括跟骨后、肩峰下及喙突下粘液囊的骨软骨瘤病；然而，据我们所知，髌骨下粘液囊骨软骨瘤病的报道却从未在英文文献中见到过。

Results There were 8 angiomyolipomas, 2 leiomyomas, 2 multilocular cystic nephromas, 1 hemangioma and 1 mesoblastic nephroma. Only multilocular cystic nephroma and leiomyoma have special characteristics that can be determined from RCC.

典型的平滑肌瘤和多囊性肾瘤在CT上有可与肾癌鉴别的特征性表现：平滑肌瘤为规则圆形，边界清楚，密度均匀，CT值略高于肾实质，无钙化，弱强化；多囊性肾瘤为边界清楚的包块，可见边缘锐利含多个分隔的肿块，分隔之间为囊腔，囊内容物的CT值与水相似或稍高，而错构瘤、海绵状血管瘤、慢性肾脓肿、中胚层肾瘤在CT上无法与肾癌鉴别。

Results: Although most cases (11/16) were typical and clearly classified on MRI, atypical cases were also observed, such as meningioma of long T1/T2 signal intensity with small cystic foci, and neurinoma of iso intensity and homogenous enhancement without cystic change or enlargement of internal acoustic meatus.

结果：尽管多数神经鞘瘤(5/8)和脑膜瘤(6/8)具有典型的MRI表现特征并仅经MRI即可得到正确鉴别，但部分病例(5/16)为不典型表现者，如脑膜瘤呈长T1长T2信号并伴有囊变，以及神经鞘瘤呈等信号、均匀强化且不伴有囊变或内听道扩大者，鉴别诊断困难。

Results:In this group there were 5 mucinous cystadenoma; 4 serous cystadenoma; 4 teratoma; 2 lager ovarian cyst; 4 subserous leiomyoma of uterine. The massive cystic-solid tumor with irregular cystic wall was seen in mucinous cystadenoma and serous cystadenoma; Teratoma appeared non homogenous density with fat density mass; Subserous leiomyoma of uterine showed large cystic tumor with clear edge, and the size of uterine was normal.

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。
