Hypothalamic hamartoma is the most common detectable cerebral lesion causing precocious puberty. Two histologically confirmed cases were studied by computerized tomography (CT) and magnetic resonance (MR) imaging. T2 weighted, sagittal MR images were superior to CT in delineating the tumor from surrounding grey matter. The lesion was isointense to grey matter on T1 weighted images allowing exclusion of other hypothalamic tumors. MR will undoubtedly become the imaging modality of choice in the detection of hypothalamic hamartoma.
下丘脑错构瘤是导致性早熟的最常见可检测到的脑内病变。通过计算机断层扫描（CT）和磁共振（MR）成像对两例经组织学确诊的病例进行了研究。在将肿瘤与周围灰质区分开来方面，T2加权矢状面MR图像优于CT。在T1加权图像上，该病变与灰质信号强度相等，有助于排除其他下丘脑肿瘤。毫无疑问，MR将成为检测下丘脑错构瘤的首选成像方式。
