摘　　要：目的分析鞍区不典型囊实性病变的CT及MRI影像学表现。方法回顾性分析18例经病理证实的不典型鞍区囊实性病变的CT及MRI影像学表现。所有病例术前均行CT及MRI检查,由2名高年资医生回顾阅片,对照术中所见及术后病理分析影像征象。结果18例不典型病例中,病理证实为垂体瘤伴卒中3例,海绵状血管瘤2例,血管母细胞瘤2例,生殖细胞瘤3例,脊索瘤3例,颅咽管瘤3例,毛细胞星形细胞瘤2例。18例不典型囊实性病例中,病灶最长径均大于3cm,大部分无法有效的根据垂体与病灶关系作出准确定位。回顾性分析病灶的特点,通过病灶影像学特点及临床病史可一定程度提高诊断正确率。结论对于鞍区体积较大的囊实性病变,需结合CT及MRI检查,观察病变的范围、形态、大小及强化程度等影像学征象,并结合临床病史才能避免误诊。Objective Analysis of CT and MRI imaging findings of atypical cystic and solid lesions in the sellar region.Methods The CT and MRI findings of 18 cases of pathologically proven atypical cystic-solid lesions in the sellar region were retrospectively analyzed.CT and MRI examinations were performed in all cases before operation,and the images were reviewed by two senior doctors,and the imaging signs were compared with intraoperative findings and postoperative pathological findings.Results Among the 18 atypical cases,3 cases were pathologically confirmed pituitary tumors with stroke,2 cases were cavernous hemangioma,2 cases were hemangioblastoma,3 cases were germ cell tumors,3 cases were chordoma,3 cases were craniopharyngioma,and 3 cases were 2 cases of cellular astrocytoma.Among the 18 atypical cystic-solid cases,the longest diameter of the lesions was greater than 3cm,and most of them could not be effectively located according to the relationship between the pituitary and the lesions.Retrospective analysis of the characteristics of the lesions,the diagnostic accuracy rate can be improved to a certain extent through the imaging characteristics and clinical history of the lesionst.Conclusion For large tumors in Sellar region,CT and MRI should be combined to observe the range,shape,size and enhancement of the lesions,and clinical history to avoid misdiagnosis.
