【摘要】：目的探討非特異性肉芽腫性前列腺炎(nonspecific granulomatous prostatitis,NSGP)類似前列腺癌(PCa)的MRI特征表現(xiàn)。方法回顧性分析3例術(shù)前MRI表現(xiàn)類似PCa特征且術(shù)前誤診為PCa的NSGP患者臨床、MRI及病理學(xué)資料。結(jié)果 3例PSA均有增高,平均13.18 ng/ml,病理結(jié)果均為NSGP,3例T_2WI上外圍帶均見低信號(hào),2例為局灶性,1例為彌漫性;DWI上病變呈輕度擴(kuò)散受限;MRS病灶ROI取點(diǎn)Cit/Cho+Cr值均有倒置,但Cho峰值與正常信號(hào)區(qū)相近,提示Cho為相對(duì)升高;動(dòng)態(tài)增強(qiáng)(DCE))病變呈早期強(qiáng)化、后期減退,時(shí)間-信號(hào)強(qiáng)度曲線類型為Ⅲ型即流出型曲線。結(jié)論 NSGP多參數(shù)(T_2WI、DWI、DCE、MRS)MRI特征與Pca非常類似,但對(duì)擴(kuò)散輕度受限、Cit/Cho+Cr值雖有倒置、但Cho峰值與正常信號(hào)區(qū)基本相近的病例,要考慮到NSGP的可能性,在患者行根治性手術(shù)前建議行穿刺活檢,避免不必要的手術(shù)。
[Abstract]:Objective to investigate the MRI features of nonspecific granulomatous prostatitis (NSGP) similar to prostate cancer (PCA). Methods the clinical and pathological data of 3 NSGP patients who had similar PCa features before operation and misdiagnosed as PCa before operation were analyzed retrospectively. Results PSA was increased in 3 cases (mean 13.18 ng / ml). The pathological results showed that the peripheral zone of T_2WI in all 3 cases was NSGPG. All of the 3 cases had low signal intensity and 2 cases were focal lesions. One case showed mild diffusion-limited lesions on DWI. All the Cit/Cho Cr values at the ROI point of MRS lesions were inversed. However, the peak value of Cho was close to the normal signal region, suggesting that Cho was relatively elevated, dynamic contrast enhancement showed early enhancement and decreased in the later stage, and the time-signal intensity curve was type 鈪，
