UNASSIGNED: A 4.5-month-old female infant was admitted with episodes of paroxysmal nystagmus. Parents reported fast horizontal eye movements lasting up to 30 s, with one episode accompanied by vomiting. Comprehensive differential diagnosis was considered from epileptic nystagmus to intoxications and both central and peripheral vestibular etiologies. During the observation on ward, connection between the baby\'s positioning and nystagmus was identified. The diagnostic roll test confirmed a transient positional geotropic nystagmus. The diagnosis aligned with BPPV characteristics, pointing to the right lateral semicircular canal canalolithiasis. A successful Lempert roll maneuver was performed with prompt effect. To further support the diagnosis and research, we introduced a semiautomatic video-oculography method.
UNASSIGNED: This case highlights a rare instance of BPPV in an infant. The clinical findings combined with the effectiveness of the repositioning maneuvers support the diagnosis of right lateral semicircular canal lithiasis. Despite the rarity of this condition in such a young-age group, the need for thorough diagnostic evaluations is emphasized. In order to document the case, we also present a semiautomatic video analysis pipeline for analyzing abnormal eye movements in a home setting.
■一名4.5个月大的女婴因阵发性眼球震颤而入院。父母报告说,快速的水平眼球运动持续了30秒,一次发作伴有呕吐。从癫痫性眼震到中毒以及中央和周围前庭病因,都考虑了综合鉴别诊断。在病房观察期间,确定了婴儿的定位和眼球震颤之间的联系。诊断滚动测试证实了瞬态位置性眼球震颤。诊断符合BPPV特征,指向右外侧半规管管结石。成功地进行了Lempert翻滚动作,效果迅速。为了进一步支持诊断和研究,我们介绍了一种半自动视频眼图方法。
■此案例突出了婴儿中罕见的BPPV实例。临床发现与重新定位操作的有效性相结合,可以诊断右外侧半规管结石。尽管这种情况在这样一个年轻的群体中很少见,强调需要进行全面的诊断评估.为了记录案件,我们还提供了一个半自动视频分析管道,用于分析家庭环境中异常的眼球运动。
