原发性颅内肿瘤患者脑囊液细胞学检查

Analysis of brain cystic fluid cytology of primary intracranial tumor

目的:探讨脑囊液细胞学检查对提高颅内占位病变定性的准确率。方法:对12例原发性颅内肿瘤患者脑囊液的检查结果进行分析。结果:其定性阳性率竟高达66.6%(8/12),虽比手术病理报告的90%(9/10)低,但比头颅CT或MR定性阳性率33.3%(4/12)高。结论:脑囊液的细胞学检查可作为术前颅内肿瘤影像学定性诊断的重要补充,亦可为病理诊断手段之一。

Objective：To improve the positive rate in the nature of primary intracranial tumor.Methods： 12 patients with primary intracranial tumor were carried by brain cystic fluid cytology. Results：The positive rate of brain cystic fluid cytology was 66.6%.Although it is lower than that of pathology （90%） ,but higher than that of CT/MR image（33.3%）.Conclusion：The character of brain cystic fluid cytology is discussed.It is important supplement for primary intracranial tumor in nature of CT/MR image and pathology.
