中文摘要 | Lhermitte-Duclos氏疾病為一罕見且生長緩慢之小腦腫塊病灶。我們提出一例Lhermitte-Duclos氏疾病在磁振造影上的影像表現。此病灶位於後腦窩,顯示典型的條紋狀形態,以T2為主影像表現高訊號,以T1為主影像則為低訊號,且有少許顯影增強現象。並有小腦葉增厚的情形。這些磁振影像之特色有助於正確診斷。 |
英文摘要 | Lhermitte-Duclos disease (dysplastic gangliocytoma) is a rare and slowly growing mass lesion in the cerebellum. We report a case of Lhermitte-Duclos disease with MR imaging. The mass lesion at the posterior fossa shows the characteristic MR appearance of the striated pattern of hyperintensity on T2-weighted images and hypointensity on T1-weighted images with slight enhancement. Thickened folia are present. These features on MR imaging may contribute to the correct diagnosis. |
