目的探讨侧脑室神经上皮囊肿的影像学特点及其鉴别诊断。方法回顾性分析8例侧脑室神经上皮囊肿患者的临床、影像学及病理学资料。结果8例患者中男5例,女3例,年龄6~28岁,平均18.4岁。囊肿大小1.2cm×1.5cm~7.2cm×5.3cm不等。1例囊肿位于右侧侧脑室三角区并延伸至前角,呈双卵圆形。余7例位于左、右侧侧脑室三角区内各3例,1例位于左侧侧脑室后角内,呈类圆形或卵圆形。壁菲薄,未见壁结节。囊液密度和信号与脑脊液信号相似,增强扫描囊壁囊液均未见强化。脉络丛被不同程度推挤移位。CT侧脑室造影示对比剂包绕于囊肿周围而未进入囊肿内。结论侧脑室神经上皮囊肿具有较为典型的影像学表现,可对该病进行准确的术前诊断。
Objective To investigate the imaging features and differential diagnosis of lateral cerebral venous epithelial cyst. Methods The clinical, radiological and pathological data of 8 patients with neuronal epithelial cyst in the lateral ventricle were retrospectively analyzed. Results 8 patients were 5 males and 3 females, aged 6 to 28 years, an average of 18.4 years old. Cyst size 1.2cm × 1.5cm ~ 7.2cm × 5.3cm range. One case of cyst located in the right lateral ventricle triangle and extended to the anterior horn, was double oval. The remaining 7 cases were located in the left and right lateral ventricle triangle in 3 cases, 1 case located in the left ventricular posterior horn, were round or oval. Thin wall, no wall nodules. Cystic fluid density and signal similar signals and cerebrospinal fluid, cystic fluid enhanced cyst fluid enhancement were not enhanced. Choroid plexus is pushed to varying degrees of displacement. Computed tomography angiography showed contrast agent surrounding the cyst but not into the cyst. Conclusion The lateral ventricle neuroepithelial cyst has the typical imaging findings, which can be used to accurately diagnose the disease.
