【摘要】：目的分析探讨中枢神经系统胚胎源性肿瘤,NOS(CNS embryonal tumour,not otherwise specified)的MRI影像特点,以提高对本病的认识。方法回顾性分析14例经手术及病理证实的幕上中枢神经系统胚胎源性肿瘤,NOS型的MRI及临床、病理资料并复习文献。结果所有病例均为单发,8例累及两个以上的脑叶;9例直径大于5 cm,平均直径5.4 cm;灶周水肿表现为较轻(5/14),甚至无(5/14);病灶呈囊实性多见(12/14);5例可见到多囊结构,形成所谓"肠襻"状改变;在T_1WI(10/14)、T_2WI(11/14)图像上信号混杂,流空(5/14)与出血(6/14)信号较常见;增强后呈花环状或结节中重度强化(13/14)。结论幕上中枢神经系统胚胎源性肿瘤NOS临床、病理及影像学特点可参照CNS PNET的临床、病理及影像学特点,MRI表现具有体积大、信号混杂等特点,有助于其诊断与鉴别。
[Abstract]:Objective To study the MRI features of embryonic-derived tumor and NOS (CNS) embryonic-derived tumor (NOS) in central nervous system (CNS), in order to improve the understanding of the disease. Methods 14 cases of central nervous system embryonic-derived tumors, NOS-type MRI and clinical, pathological data and literature review were retrospectively analyzed. Results All cases were single-shot,8 cases involving more than two lobes,9 cases with a diameter of more than 5 cm and an average diameter of 5.4cm, and the edema in the range was less than 5/14, and even none (5/14); the focus was more and more solid (12/14);5 could see the polycystic structure. The so-called "enteromorpha"-like changes were formed; in the images of T _ 1WI (10/14), T _ 2WI (11/14), the signal was mixed, and the signal was more common than that of the hemorrhage (6/14); after the enhancement, the signal was more or more severe (13/14). Conclusion The clinical, pathological and imaging features of the NOS in the central nervous system of the supratentorial central nervous system can be referred to the clinical, pathological and imaging characteristics of the CNS PNET, and the MRI features have the characteristics of large volume, high signal and the like, and can be used for the diagnosis and identification of the central nervous system.
