Benign paroxysmal positional vertigo is a common type of vertigo seen by the otolaryngologist; however, intracranial tumors can mimic benign paroxysmal positional vertigo in their presentation. A review of patients seen in the Department of Otolaryngology at The Ohio State University between July 1992 and August 1996 identified five patients with intracranial pathologic conditions mimicking benign paroxysmal positional vertigo. These patients were first seen with episodic vertigo associated with positional change. Failure of the symptoms to respond to the particle repositioning maneuver or the finding of associated auditory or neurologic symptoms prompted further evaluation by magnetic resonance imaging of the brain, which revealed intracranial pathologic conditions including two meningiomas, a vestibular schwannoma, a glioma, and a lipoma. These findings suggest that patients seen with symptoms like those of benign paroxysmal positional vertigo who do not show improvement after undergoing the particle repositioning maneuver or those who describe associated auditory or neurologic symptoms should have magnetic resonance imaging done to rule out intracranial pathologic conditions. Additionally, benign paroxysmal positional vertigo and intracranial tumors may coexist.
良性阵发性位置性眩晕是耳鼻喉科医生常见的一种眩晕类型；然而，颅内肿瘤在临床表现上可模仿良性阵发性位置性眩晕。回顾1992年7月至1996年8月在俄亥俄州立大学耳鼻喉科就诊的患者，发现有5例颅内病变患者临床表现模仿良性阵发性位置性眩晕。这些患者最初表现为与体位改变相关的发作性眩晕。症状对颗粒复位手法无反应，或发现伴有听觉或神经症状，促使通过脑部磁共振成像进行进一步评估，结果显示颅内病变，包括2例脑膜瘤、1例前庭神经鞘瘤、1例胶质瘤和1例脂肪瘤。这些发现表明，出现类似良性阵发性位置性眩晕症状的患者，在接受颗粒复位手法后无改善，或描述伴有听觉或神经症状，应进行磁共振成像检查以排除颅内病变。此外，良性阵发性位置性眩晕和颅内肿瘤可能并存。
