Gingival salivary gland choristoma

A unique example of a gingival salivary gland choristoma together with a gingival cyst is described in a human autopsy specimen of periodontal tissues. A choristoma is a tumor-like growth which is derived from primordial cells which have been displaced from their original tissue or organ. Only 6 other examples of the gingival salivary gland choristoma have been described in the world literature.     

婴儿先天性胆总管囊肿16例诊治分析

１９８５￣１９９４年作者单位共收治小儿先天性胆总管囊肿１０５例，其中年龄小于１２个月者１６例，占１５．２％，本病临床表现不典型，易延误诊治，超声检查可在产前检出本病，作者认为对于待续性黄疸的婴儿，保守治疗不宜时间过长，应积极手术探查。     

Mesenteric cyst with milk of calcium

A mesenteric cyst with milk of calcium in an adult patient is presented. Preoperative evaluation included plain film, ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI). To our knowledge, the presence of milk of calcium in a mesenteric cyst has not been previously described.     

动脉瘤样骨囊肿

动脉瘤样骨囊肿属骨的瘤样病变。本文将16年来收检的16例、结合文献复习,阐明其定义,好发部位和年龄;阐述其富有特征性的临床病理表现。作者赞同Lichtenstein的观点,认为此病是由某种原因造成的局部循环障碍,导致病变骨内静压明显升高,形成扩张充血的血管床病变而造成。研究探讨这些血循环障碍引起的不同结果,可能对病因学有重要价值。     

小切口手术治疗肾囊肿14例体会

目的分析讨论应用小切口手术治疗单纯性肾囊肿的临床特点及体会。方法总结自1996年1月至2004年10月14例应用小切口手术行囊肿去顶术的临床资料。结果小切口手术组14例,囊肿单发均位于肾中下极及中部背侧,手术时间30~90m in,术后未发生并发症,住院日5~8d。随访半年~1年均无复发。结论小切口手术治疗单纯肾囊肿具有手术操作简便、创伤小、恢复快、降低住院日等优点,适用于肾中下极及肾中部背侧的单纯肾囊肿。     

坐骨结节囊肿的CT诊断

目的 探讨坐骨结节囊肿的CT表现及CT扫描的诊断价值。方法 回顾性分析12例经手术及病理证实的坐骨结节囊肿的CT表现。所有病例均摄骨盆正位X线平片及行CT平扫，其中2例尚行CT增强扫描。结果 12例骨盆正位片示坐骨结节骨质及其附近软组织均未见异常改变；CT平扫于坐骨结节与臀大肌之间的间隙内可见单个多房囊性水样密度肿块，边欠清，其横断面略呈锥形，锥尖朝前。增强扫描示肿块内无明显强化，但分隔及边缘可有轻度强化，且厚薄不均。结论 坐骨结节囊肿的CT表现较有特征性，CT扫描具有极高的诊断价值。     

MESENTERIC CYST

Mesenteric cyst is one of the rarest abdominal tumours, with approximately 820 cases reported since 1507. The incidence varies from 1 per 100000 to 250000 admissions. The lack of characteristic clinical features and radiological signs may present great diagnostic difficulties. The cyst may present in one of three ways: (i) non-specific abdominal features; (ii) an incidental finding; or (iii) an acute abdomen. Abdominal pain is the major presenting symptom. Abdominal mass is found in more than 50% of cases and 40% of cases are discovered incidentally. More than one aetiological mechanism is probably involved in the development of mesenteric cysts. Mesenteric cysts have been reported from the duodenum to the rectal mesentery but are most commonly located in the ileal mesentery. Malignant cysts occur in less than 3% of cases. Enucleation of the cyst is the treatment of choice. Knowledge of these tumours is important due to the various complications associated with suboptimal surgical management. Two cases of mesenteric cysts are presented including a recurrent mesenteric cyst in a post-partum woman demonstrating the inferior technique of internal marsupialization. The association of mesenteric cyst with pregnancy is discussed.     

卵巢肿瘤细胞DNA及RNA含量的定量分析及其临床意义

本资料对９３例不同性质的卵巢肿瘤细胞ＤＮＡ及ＲＮＡ含量进行了定量研究，其中５０例良性、４３例恶性。并对患者进行１～５年的随访。结果是卵巢良性肿瘤的异倍率（假阳性）为４４％，恶性肿瘤异倍率为８６．０％。以“标准ＤＩ”及“标准ＲＩ”为指标判断卵巢肿瘤性质的准确率较以“异倍性”为高，且双指标同时应用高于任一单指标：对卵巢良恶性肿瘤的诊断准确率分别为９０％和９５．３％。提出“标准ＤＩ”和“标准ＲＩ”是判断卵巢肿瘤性质的理想指标。且ＤＮＡ及ＲＮＡ含量与卵巢癌预后有密切关系。     

卵巢肿瘤蒂扭转的CT诊断价值探讨(附12例报告)

目的:评价CT对卵巢肿瘤蒂扭转的诊断,探讨囊壁局限性增厚对卵巢肿瘤蒂扭转的诊断价值。方法:对12例卵巢肿瘤蒂扭转的CT征象作回顾性分析,对卵巢肿瘤蒂扭转囊壁局限性增厚CT表现与文献报道的B超特征性表现双肿块声像图作对照分析。结果:本组12例病例中11例为卵巢囊性或者囊实性肿瘤,其中6例有局限性囊壁增厚,除此之外卵巢肿瘤蒂扭转还有其它许多CT征象,如卵巢肿瘤囊肿壁及囊肿内出血,附件输卵管增粗、显示,盆腔内积液,子宫位置偏位。结论:只要我们能密切结合临床,CT能对大多数卵巢肿瘤蒂扭转作出正确诊断。     

Interhemispheric multiloculated ependymal cyst with dysgenesis of the corpus callosum: a case in a preterm fetus

Introduction The authors report a case of interhemispheric ependymal cyst accompanied with agenesis of the corpus callosum in a fetus. Discussion Routine ultrasound and subsequent magnetic resonance imaging of a 20-year-old woman at 33 weeks and 1 day of gestation detected a large interhemispheric cystic lesion in the fetal cranial cavity. Caesarian section was carried out at 36 weeks because of the progressive enlargement of the fetal head. The cyst was multiloculated and a cyst peritoneal shunt placement resulted in collapse of the drained cyst components followed by enlargement of others. After wrack-a-mole-like shunt revisions, open surgery was performed at the age of 2 years. Cyst walls were fenestrated and the cavities were communicated with each other and eventually with the lateral ventricle. Pathological diagnosis of the cyst wall was ependymal cyst. The boy is now 3 years old, and growing without apparent developmental delay or recurrence. Current concept and management policy of the interhemispheric cyst accompanied with agenesis of the corpus callosum is reviewed.
