中枢神经细胞瘤(central neurocytoma,CNC)是中枢神经系统肿瘤中比较少见的一类,约占颅内原发肿瘤的0.25%～0.5%[1]。笔者回顾性分析本院3例经手术病理证实的CNC患者的影像学表现和病理,复习相关文献,以提高诊断准确性。1病例报告例1男,31岁。头痛伴呕吐3个月入院。体格检查:神志清楚,未见感觉、运动异常,生理反射存在,病理反射未引出。CT表现:右侧侧脑室体部见50mm×45mm大小的等密度团块影,其内见斑片状钙化影,双侧侧脑室扩大,中线稍向左侧移位。MR表现:右侧侧脑室体部见等T1等T2团块影,
Central neurocytoma (central neurocytoma, CNC) is a relatively rare type of central nervous system tumors, accounting for about 0.25% to 0.5% of intracranial tumors [1]. The author retrospectively analyzed 3 cases of pathologically confirmed patients with CNC imaging and pathology, review the relevant literature to improve the diagnostic accuracy. 1 case report 1 male, 31 years old. Headache with vomiting 3 months admitted. Physical examination: conscious, no feeling, abnormal exercise, the presence of physiological reflex, pathological reflex did not lead. CT manifestations: right side of the body of the brain to see the same size of 50mm × 45mm size of the clumps, which see patchy calcifications, bilateral lateral ventricle expansion, slightly shifted to the left midline. MR performance: see the right side of the ventricle and other body volume T2 T1 block shadow,
