目的通过总结磁共振平扫与局部靶扫对于临床少见的下丘脑错构瘤的影像学特点,提高对于该病核磁检查的认识及诊断水平。方法分析我院近年来核磁诊断的下丘脑错构瘤的影像表现,总结其影像学特有征象及表现。结果 4例诊断下丘脑错构瘤患者中均有痴笑样癫痫的发作,其中2例伴有儿童型性早熟表现,4例均行手术治疗,一年后随访痴笑样癫痫发作均停止。结论由于下丘脑错构瘤较小,较易漏诊,核磁靶扫对于有痴笑样癫痫发作患者的诊断有重要意义。
Objective To summarize the imaging characteristics of hypothalamic hamartoma, which is rare in clinic, by magnetic resonance plain scan and local target scan, and to improve the level of understanding and diagnosis of this disease by magnetic resonance imaging. Methods The MRI findings of MRI of hypothalamic hamartoma in our hospital in recent years were analyzed. The imaging features and manifestations were summarized. Results All the 4 patients diagnosed as hypothalamic hamartoma had smirk-like epilepsy. Among them, 2 patients had precocious puberty and 4 patients underwent surgical treatment. One year later, the clue-like seizures were stopped. Conclusion Due to the smaller hypothalamic hamartoma and easier misdiagnosis, nuclear magnetic resonance imaging is of great significance for the diagnosis of patients with gigantic seizures.
