本文对16例鞍区生殖细胞瘤的临床和CT资料进行了分析。结果表明,本病好发于儿童及青年,女性多见。临床常表现为尿崩症、视力障碍及丘脑下部-垂体功能紊乱。CT检查可确定肿瘤的部位,反映肿瘤的内部结构,提供恶性肿瘤的诊断依据以及确定脑积水的梗阻部位、发现蝶鞍局限性骨质破坏等。鞍区生殖细胞瘤起源于丘脑下部,如漏斗、视交叉、垂体柄等。肿瘤平扫呈高密度,少数可有多发、散在、小的低密度区;增强CT强化显著,低密度区无强化。肿瘤形态不规则,边界不清楚,沿脑脊液循环种植性转移及沿邻近室管膜浸润生长等,可视为恶性肿瘤征象,后者对本病具有特征性意义。另外,部分病例鞍区与松果体医生殖细胞瘤并存,检查中要注意寻找。

Yet, whether CT examination could reflex the pathological grade, DNA contents (DI), proliferation indices(PI) as well as prognosis of the patients of brain tumors so as to set more scientific basis for clinical diagnosis and treatment is still a very important problem to be further explored.

As an advanced method of examination, CT diagnosis of brain tumors is more accurate for localization. Yet, whether CT examination could reflex the pathological grade, DNA contents (DI), proliferation indices(PI) as well as prognosis of the patients of brain tumors so as to set more scientific basis for clinical diagnosis and treatment is still a very important problem to be further explored. In this paper, the relationship between CT value and DI, PI as well as postoperative survival was studied in 60 cases of astrocytomas in brain. The results showed that CT values were positively correlated with DI and PI. On the other hand, the higher the CT value, the poorer the prognosis. There were significant differences in CT value, DI, PI and postoperative survival among the following three pathological grade groups. The corresponding CT values before/after contrast enhancement for grade Ⅰ, Ⅱ and Ⅲ-Ⅳ groups were 29 31±1 19/40 25±0 60, 39 31±1 91/44 77±0 99 and 46 10±1 22/65 60±1 46. The DI and PI and postoperative survival time were 1 17±0 17, 1 21±0 05, 1 31±0 13; 36 00±2 57, 39 88±2 88, 46 57±4 36 and 72, 55, 26 months for grade Ⅰ, Ⅱ and Ⅲ-Ⅳ groups, respectively. There fore, CT examination of brain tumer may perfectly reflex its nature and prognosis, giving an important mark in clinical practice.

CT扫描技术的应用,大大提高了对脑瘤定位诊断的准确性。但CT检查能否同时判断肿瘤的大致分级、DNA含量(DI)、细胞增殖指数(PI)及预后情况,从而更好地为临床提供诊断和治疗依据,这是目前需要探索的一个重要课题。本文对60例星形细胞瘤的CT值与其病理分级、DNA含量、PI值以及术后生存期进行了初步研究,结果显示:(1)CT值与病理分级密切相关,即按病理为Ⅰ、Ⅱ和Ⅲ-Ⅳ级的分组顺序,各组的CT值逐渐增大;(2)CT值与DNA含量和细胞增殖指数呈正相关关系。即按上述病理分级,各组的DI和PI值均随CT强化(或非强化)值的增大而逐渐增大;(3)CT值与其预后的关系十分密切,即随CT值的增高,术后生存时间缩短。在CT非强化值分别为2931±119、3931±191、4610±122和CT强化值分别为4025±060、4477±099、6560±146的3组中,其术后存活时间分别为72、55和26个月,呈负相关关系。本研究结果表明,CT值可以作为推测星形细胞瘤的分级、DNA含量水平、细胞增殖程度及术前对预后的综合判断依据,对提高脑瘤的临床诊治水平具有重要参考价值。

目的:研究腹膜后脂肪肉瘤的CT、MRI诊断。方法:本组经病理证实19 例,男8例,女11 例,平均年龄54.0 岁。CT检查13例,其中CT强化扫描6 例;MRI检查9例。结果:19 例中发生于肾周围8例,其他部位11例。18例单发,1例多发。肿瘤直径> 10cm 18例,< 10cm 1例。肿瘤内含有脂肪组织密度或信号强度者18例,其中1 例呈均匀脂肪改变,17 例脂肪肉瘤内见条、片、块肌肉组织改变;1例呈完全肌肉样改变。肿瘤侵犯周围组织器官9例,压迫改变10例。结论:腹膜后巨大肿块,含有脂肪密度或信号强度者应诊断本病。
