目的探讨下丘脑错构瘤的CT和MRI影像表现。方法对我院2007年1月～2011年7月14例下丘脑错构瘤的CT和MRI资料进行回顾性分析。结果所有病例临床表现主要为性早熟和痴笑样癫痫。肿块与灰结节,CT表现为与皮质等密度的不增强肿块或乳头体相连。MRI表现在T1WI上与灰质等信号,在PDW和T2WI上等信号或轻度高信号,肿块不增强。结论本病应与颅咽管瘤、下丘脑胶质瘤、生殖细胞瘤鉴别。根据患者临床表现,影像学上显示灰结节或乳头体肿块,具有典型CT和MRI表现,应首先考虑本病。
Objective To investigate the CT and MRI findings of hypothalamic hamartoma. Methods The CT and MRI data of 14 patients with hypothalamic hamartoma in our hospital from January 2007 to July 2011 were analyzed retrospectively. Results The clinical manifestations of all cases were mainly precocious puberty and smoky-like epilepsy. Mass and gray nodules, CT showed no increase in cortical density with the mass or nipple body connected. MRI showed on T1WI and gray matter and other signals, PDW and T2WI superior signal or mild high signal, the mass is not enhanced. Conclusion The disease should be with craniopharyngioma, hypothalamic glioma, germ cell tumor identification. According to the clinical manifestations of patients, the imaging showed gray nodules or papillary mass, with typical CT and MRI manifestations, should first consider the disease.
