Arachnoid cyst of the middle fossa with paradoxical changes of the bony structures

Summary Two patients with an arachnoid cyst of the middle fossa showed paradoxical changes of the adjoining bony structures of the skull. There was a diminution of the middle fossa and hyperplasia of the sphenoid sinus (pneumosinus dilatans) as well as a marked bulging of the squamous part of the temporal bone. In one case in which scinticisternography was performed, communication between the cyst and the subarachnoidal space was proven as well as an extremely slow cerebrospinal fluid circulation in the cyst. The pathogenesis of the cyst is discussed, based upon the structural changes of the skull, the angiographic findings and the locally disturbed cerebrospinal fluid circulation. The primary disturbance seems to be a temporal lobe agenesis.     

椎管内肠源性囊肿手术治疗与评价

目的总结了椎管内肠源性囊肿的临床特点、诊断和治疗.方法分析了8例椎管内肠源性囊肿的临床资料,并结合了文献加以分析探讨.结果8例中6例为儿童,男女之比为3:1,囊肿位于颈段3例,胸段例,颈胸交界2例,腰骶段1例.囊肿全切除4例,近全切除1例,部分切除3例,均取得了较好疗效.结论椎管肠源性囊肿是先天性良性病变,早期诊断及手术治疗是最好的选择.     

Papillary thyroid carcinoma in a thyroglossal cyst

The incidence of Papillary Thyroid Carcinoma in a Thyroglossal Cyst is rare. Only about 160 cases have been reported in the last 85 years. We report a case of Thyroglossal Cyst who underwent Sistrunk ’s Operation. The Cyst was reported to contain a focus of papillary thyroid carcinoma. In the absence of metastases in thyroid gland and neck nodes, only thyroid suppression with Thyroxine was given. After I year of follow-up there are no metastases. The importance of Sistrunk’s operation lies not only in complete removal of Thyroglossal Cyst but also in management of small foci of Papillary thyroid Carcinoma.     

甲状软骨侧切术治疗声门旁间隙病变

目的：探讨经一侧甲状软骨板入路行声门旁间隙手术的可行性和优越性。方法：3例位于声门旁间隙的喉黏液囊肿患者，采用一侧甲状软骨“U”形部分切除术入路切除囊肿；1例喉外伤声门旁间隙异物采用一侧甲状软骨板垂直切开取出异物。结果：3例喉黏液囊肿患者随访1年均无复发，声音恢复正常状态；1例喉外伤异物患儿术后双侧声带运动正常，声门闭合良好。结论：经一侧甲状软骨板切开或部分切除入路，可清晰显露声门旁间隙，在直视下彻底切除囊肿或取出异物，手术创伤小，不破坏喉的框架结构，不损伤喉黏膜，术后无并发症，是处理声门旁间隙良性病变的理想手术方式。     

Rapid enlargement of a choledochal cyst: antenatal diagnosis and delayed primary excision

A case of choledochal cyst (CC) antenatally diagnosed at 29 weeks' gestation is reported. Rapid enlargement of the cyst soon after delivery resulted in complete gastric outlet obstruction (GOO). The lesion was treated by external drainage as a temporary maneuver, with delayed cyst excision and hepaticoduodenostomy at the hepatic hilum performed at 81 days of age. Surgical treatment of CC in early infancy has been reported to be safe and effective. However, delayed primary excision would be an alternative procedure, especially in rare cases showing rapid enlargement resulting in GOO, since this choice has the potential advantage of allowing weight gain and improved nutritional status without risking interim complications due to the drainage procedure.

中枢神经系统肠源性囊肿的形态及免疫组化研究

目的：观察中枢神经系统肠源性囊肿的组织形态及免疫组织化学特征。方法：使用病理组织学及免疫组织化学方法对３１例中枢神经系统不同部位的肠源性囊肿进行研究。结果：囊肿壁上皮可为单层或复层扁平、立方、柱状上皮；一些病例可见两种以上上皮组织成分，并相互移行；某些病例，在囊肿壁内可含有黑色素、软骨、平滑肌、粘液腺等多种组织成分。免疫组织化学染色ＥＭＡ均呈阳性；ＣＥＡ染色仅一例阴性，而此例ＮＳＥ阳性，故应诊断为神经上皮性囊肿；Ｓ－１００和ＣＫ染色结果不固定；Ｖｉ－ｍｅｎｔｉｎ和ＧＦＡＰ均呈阴性。结论：肠源性囊肿的组织形态和免疫组织化学特点可作为鉴别其他类型囊肿的依据。     

Prenatally detected cystic neuroblastoma

A case of adrenal cystic neuroblastoma (NB) detected by prenatal ultrasonography (US) is presented. The suprarenal mass initially showed pure cystic features on a variety of imaging studies such as US, computed tomography, and magnetic resonance imaging. Tumor markers were negative. The mass was suspected to be an adrenal hemorrhage rather than a NB. Three months later, although the diameter was unchanged, the thickness of the cyst wall seemed to have slightly increased. Surgical exploration revealed an adrenal cystic tumor and histology showed a NB in situ. Forty-five infants with prenatally detected NB were found in the English literature; about one-half of them were cystic NBs, and most had a favorable outcome. Accepted: 29 July 1996     

腹腔镜手术治疗过大卵巢囊肿手术8例报告

目的探讨腹腔镜治疗过大卵巢囊肿手术的可行性和适应征。方法2004年6月～2005年4月，在腹腔镜下治疗8例过大卵巢囊肿，2例卵巢囊肿切除术，6例卵巢囊肿剥除术。结果8例均获成功，无中转开腹，无手术并发症。手术时间60～95min，术后2～3d出院。结论过大卵巢囊肿可行腹腔镜手术治疗。     

合并肾囊肿的肾细胞癌临床特点(附64例报道)

目的:总结肾癌合并有肾囊肿病例的临床特点,探讨合并有肾囊肿肾癌病例的诊断、治疗方法,为研究肾癌的发病机制及其预防提供线索。方法:回顾我院1996年5月至2004年1月收治的64例肾癌合并有肾囊肿病例,分析其临床特点,比较B超、CT、MRI在诊断该疾病中的特点和作用,并与同期收治的106例没有合并肾囊肿肾癌病例的临床资料进行分析比较。结果:B超、CT和MRI在诊断肾癌合并有肾囊肿病例时,检查出肾囊肿的准确性分别为37%、24%和35%,而全部64例病理检查中又查出15例(23%)囊性占位性病变;该64例患者全部进行了手术治疗,术后病理报告为肾癌,病理诊断:透明细胞癌61例,颗粒细胞癌2例,混合型(透明细胞癌 颗粒细胞癌)1例;与同期未合并肾囊肿的肾癌病例相比,合并有肾囊肿肾癌病例更好发于男性(P<0.007),且发病年龄较轻(P<0.05),无症状肾癌比例较少(P<0.001),小肾癌(肿瘤直径≤4cm)占比例也相对较少(P<0.024),肿瘤的病理类型和肿瘤的临床分期也有统计学差异(分别是P<0.037和P<0.043)。结论:合并肾囊肿的肾癌具有易发于男性年轻患者、以有症状的非小肾癌居多的特点。B超、CT、MRI在诊断出肾癌的同时,诊断发现肾囊肿的准确性不高,肾癌可能掩盖了对肾囊肿的诊断,联合病理检查可能增加对肾囊肿的诊断;合并有肾囊肿的肾癌有其
