【摘要】：目的歸納一組腦內(nèi)節(jié)細胞瘤病例的MRI表現(xiàn)。材料與方法回顧性分析經(jīng)手術(shù)及病理證實的5例腦內(nèi)節(jié)細胞瘤MRI表現(xiàn),探討其發(fā)病部位,腫瘤形態(tài)、邊界、信號及強化特點,并文獻復習。結(jié)果 5例節(jié)細胞瘤中位于顳葉4例、小腦蚓部1例,腫瘤呈類圓形3例、大囊大結(jié)節(jié)狀1例、不規(guī)則形1例。MRI檢查腫瘤主體T1WI呈低信號(4例)或稍高信號(1例),T2WI呈稍高信號(4例)或稍低信號(1例),同時存在信號混雜(4例),CT及MRI提示含鈣化3例。表現(xiàn)無水腫1例、輕度水腫3例、中度水腫1例。腫瘤呈輕度強化2例、中度強化3例。結(jié)論本組病例節(jié)細胞瘤MRI表現(xiàn)多樣,但基本符合良性腫瘤特點,顳葉發(fā)生率較高,易鈣化,多見于青少年,對今后臨床工作中影像診斷及鑒別診斷節(jié)細胞瘤可能提供幫助。
[Abstract]:Objective to summarize the MRI findings of a group of patients with intracerebral ganglionoma. Materials and methods the MRI findings of 5 cases of intracerebral ganglioneuroma proved by operation and pathology were retrospectively analyzed. The location, shape, boundary, signal intensity and enhancement characteristics of the tumors were discussed, and the literature was reviewed. Results of the 5 cases, 4 cases were located in temporal lobe, 1 case in cerebellar vermis, 3 cases in round shape, 1 case in large cyst nodular shape and 1 case in irregular shape. MRI showed low signal intensity (4 cases) or slightly hyperintense T1WI (1 case). T2WI showed slightly high signal intensity (4 cases) or slightly low signal intensity (1 case) and mixed signal (4 cases with), CT and 3 cases with MRI indicating calcification in 3 cases). No edema was found in 1 case, mild edema in 3 cases and moderate edema in 1 case. The tumor showed mild enhancement in 2 cases and moderate enhancement in 3 cases. Conclusion the MRI findings of ganglioma in this group are various, but basically accord with the characteristics of benign tumor. The temporal lobe is more likely to be calcified, and it is more common in adolescents, which may be helpful to the imaging diagnosis and differential diagnosis of ganglioneuroma in the future.
