摘要

本文利用3D FIESTA清楚確定三位單側Duane's retraction syndrome (DRS)的兒童（年紀分別為8歲、14個月、2歲）缺乏同側的外旋神經。其中年紀較小的二位兒童只有單純的外旋神經麻痺而沒有典型眼球內縮的表現。利用3D FIESTA高解析度影像對於DRS的診斷確立及鑑別診斷很有幫助，特別是針對沒有典型表現的病患。

並列摘要

Three children of unilateral type I Duane's retraction syndrome (DRS), aged 8 years, 14 months and 2 years were confirmed by demonstration of absence of ipsilateral abducens nerves on 3D fast imaging employing steady-state acquisition (FIESTA) MR sequence. The two younger patients had isolated abduction deficit without the characteristic globe retraction or upward/downward shooting on attempted adduction. The application of high-resolution MR imaging is useful for differential diagnosis and confirmation of DRS, especially in patients without characteristic presentations.
