Value of preoperative MRI technology in diagnosing pituitary cystic lesions
摘要
Abstract
Objective To explore the value of MRI technology in diagnosing pituitary cystic lesions,and to improve the diagnostic level of MRI imaging of pituitary cystic lesions. Methods Retrospective analysis of the MRI examination data of 31 cases with pituitary cystic le-sions confirmed pathologically from January 2013 to November 2016, including cystic pituitary tumor 16 cases,pituitary abscess 6 cases and Rathke' s cyst 9 cases,all the cases underwent MRI scan and 22 underwent enhanced GD-DTPA scan. Results 16 cases of cystic pituitary tumor,12 cases of large pituitary adenomas, micro adenoma 4 cases. 12 cases large pituitary adenomas were shown as in solid tumors in the capsule,T1WI showed low signal,while T2WI showed high signal. Capsule wall was equal signal and thickness was uneven,obvious enhance-ment,3 cases with bleeding,T1WI showed high signal,and liquid level. 4 cases of cystic adenoma,TIWI showed slightly low signal,T2WI showed high signal,edge mild enhancement,1 case had been preoperatively misdiagnosed as Rathke' s cyst,1 case of missed diagnosis. 6 ca-ses of pituitary abscess,T1WI was low or equal signal,T2WI was equal, high signals or uneven,most of the boundary was not clear,Most of the lesions in circular reinforcement or separated reinforcement,uneven parts for reinforcement,Visible near the base of skull meningeal,cav-ernous sinus area reinforcement. 2 cases of T2WI of mixed high and low signal,preoperative misdiagnosed as pituitary tumors and tumor apo-plexy. 9 cases of Rathke's cyst,5 cases were shown as slightly long T1 long T2 signal, boundary was clear,the edges slightly enhanced,4 ca-ses in T1WI,T2WI high signal,among them 2 cases misdiagnosed as craniopharyngioma. The diagnostic accuracy rates were respectively:87. 5％, 66. 7％, 77. 8％. Conclusion MRI can well show the location,shape and signal characteristics of pituitary cystic lesions in the sellar region,and can make qualitative diagnosis to a large extent,which is of guiding significance for clinical operation.关键词
