Techniques for pediatric MR imaging and computed tomography and anatomy of the orbit and intracranial visual pathways are presented and reviewed in this article. Imaging findings are presented for the following categories of abnormality: a) orbital anomalies related to congenital disorders of the brain, b) disorders of the orbit (ocular, nonocular, or multicompartmental), c) disorders of the intracranial visual pathways (suprasellar cistern, optic radiations, or occipital cortex), and d) disorders of gaze (extraocular muscles, cranial nerves, and brainstem). Careful assessment of the clinical findings, anatomic location of the visual impairment, and familiarity with disorders that often affect pediatric patients are helpful in guiding neuroimaging evaluation of the child with ocular, orbital, or central patterns of visual disturbance.
本文介绍并回顾了儿科磁共振成像和计算机断层扫描技术以及眼眶和颅内视觉通路的解剖结构。文中呈现了以下几类异常情况的影像学表现:a)与先天性脑部疾病相关的眼眶异常;b)眼眶疾病(眼部、非眼部或多腔室性);c)颅内视觉通路疾病(鞍上池、视辐射或枕叶皮质);d)注视障碍(眼外肌、颅神经和脑干)。仔细评估临床发现、视觉障碍的解剖位置以及熟悉常影响儿科患者的疾病,有助于指导对患有眼部、眼眶或中枢性视觉障碍模式儿童的神经影像学评估。
