【摘要】：目的分析颅内神经节细胞胶质瘤的临床、病理及MRI表现。方法收集我院经病理确诊颅内神经节细胞胶质25例,分析病灶部位、数量、平扫及增强信号特点、瘤周水肿情况,以探析MRI影像特点。结果 25例患者中,22例为癫痫发作,其中19例以癫痫为唯一临床表现、3例为失神发作。2例为囊性、10例为囊实性、13例为实性。T1WI上囊性患者以低信号为主,实性患者以等信号或稍低信号为主,囊实性患者两类信号兼有。T2WI上囊性患者以高信号为主,实性患者为等信号或稍高信号,囊实性患者两类信号兼有。增强扫描囊性患者无强化,实性患者以轻度强化为主,囊实性患者以明显强化及轻度强化为主。1例无水肿、15例轻度水肿、4例中度水肿、5例重度水肿。结论颅内神经节细胞胶质瘤多以癫痫发作为主,可分为囊性、囊实性及实性3种类型,不同类型患者具有不同MRI表现,结合病理特点可为临床诊治提供指导。
[Abstract]:Objective to analyze the clinical, pathological and MRI features of intracranial ganglion cell glioma. Methods 25 cases of glia of intracranial ganglion cells confirmed by pathology in our hospital were collected. The location, quantity, signal characteristics of plain scan and enhancement, and edema around the tumor were analyzed in order to analyze the imaging features of MRI. Results among the 25 cases, 22 cases were epileptic seizures, 19 cases were epileptic, 3 cases were aphasia, 2 cases were cystic, 10 cases were solid, 13 cases were solid. The signal intensity of solid patients was equal or slightly low, the two kinds of signals were both in patients with cystic solid, high signal in cystic patients on T2WI, equal or slightly high signals in patients with solid, and both kinds of signals in patients with cystic and solid. Enhancement scan showed no enhancement in cystic patients, mild enhancement in solid patients, obvious enhancement and mild enhancement in cystic and solid patients, and no edema in 1 case, mild edema in 15 cases, moderate edema in 4 cases and severe edema in 5 cases. Conclusion Intracranial ganglion cell gliomas are mainly epileptic, which can be divided into three types: cystic, solid and solid. Different types of gliomas have different MRI manifestations, which can provide guidance for clinical diagnosis and treatment combined with pathological features.
