Susceptibility-weighted Imaging in Diagnosing Brain Capillary Telangiectasia: A Case Report
利用磁敏感加權影像診斷腦部毛細血管擴張：病例報告
摘要
一位65歲肺癌患者來院接受磁振造影檢查是否有大腦轉移，經對比劑顯影的T1加權影像中發現在橋腦部位有一顯影的小病灶，此病灶在T2梯度迴訊影像呈現低訊號，但傳統T1/T2加權影像皆不可見。磁敏感加權影像中呈現明顯低訊號，並有一小延續訊號疑為引流靜脈。診斷為毛細血管擴張或過渡型毛細血管－靜脈畸形。就我們所知，腦內毛細血管擴張鮮少以磁敏感加權影像來報告。

A 65-year-old lung cancer patient was screened for intracranial metastases. Post-gadolinium enhanced T1-weighted imaging revealed a small enhancing pontine lesion slightly hypointense on T2(superscript *)-weighted gradient echo, invisible on T1-/T2-weighted imaging. Susceptibility-weighted imaging (SWI) showed marked hypointensity; a small linear hypointensity extension suggested a draining vein. Capillary telangiectasia or transitional capillary-venous malformation was diagnosed. To the best of our knowledge, brain capillary telangiectasia rarely has been previously reported by SWI.
