目的探讨中枢神经细胞瘤(CNC)的CT和MRI诊断价值,以提高对该病的认识。方法回顾性分析经手术病理证实的5例CNC的CT和MRI影像学特点。结果 4例均位于透明隔及双侧侧脑室体部前2/3,分别向一侧或两侧侧脑室内生长,1例附着于右侧侧脑室顶部向下生长,CT为等高混杂密度,其中1例可见钙化,MRI为混杂信号,4例不均匀中等或明显强化,1例未见明显强化。结论 CNC是少见的颅内肿瘤,其CT和MRI表现具有一定特点,再结合发病年龄和部位,有望在术前做出正确诊断,为临床治疗提供可靠依据。
Objective To investigate the value of CT and MRI in the diagnosis of central neurocytoma (CNC) to improve the understanding of the disease. Methods The CT and MRI features of 5 cases confirmed by surgery and pathology were retrospectively analyzed. Results All the 4 cases were located in the first two thirds of the transparent septum and bilateral lateral ventricle body, respectively one or both sides of the lateral ventricle growth, one case attached to the right side of the top of the lateral ventricle growth down, CT is the contours of mixed density , One case of calcification, MRI as a mixed signal, 4 cases of uneven or moderate enhancement, 1 case no significant enhancement. Conclusion CNC is a rare intracranial tumor with some features of CT and MRI. Combined with the age and location of the disease, CNC is expected to make a correct diagnosis before surgery and provide a reliable basis for clinical treatment.
