未经证实:少数颅内病变仅表现为位置性眩晕,极易误诊为良性阵发性位置性眩晕(BPPV),临床医生应重视本病。
UNASSIGNED:分析6例仅表现为位置性眩晕的颅内肿瘤患者的临床特征,以避免误诊。
UNASSIGNED:对2015年5月至2019年5月期间在我们诊所治疗的6例仅表现为位置性眩晕的颅内肿瘤患者进行了回顾。和临床症状,眼球震颤的特征,成像演示,并对患者的最终诊断进行评估。
UNASSIGNED:所有患者均表现为位置性眩晕和位置性眼震,包括一个在位置测试中眼球震颤下降的病例,两例左跳眼球震颤,在滚动测试中出现了一例向外性眼球震颤,一例右侧眼球震颤,还有一例左打和眼球震颤。脑部MRI显示肿瘤区域位于小脑的疣中,第四脑室,侧脑室,和小脑半球。
UNASSIGNED: A few intracranial lesions may present only with positional vertigo which are very easy to misdiagnose as benign paroxysmal positional vertigo (BPPV); the clinicians should pay more attention to this disease.
UNASSIGNED: To analyze the clinical characteristics of 6 patients with intracranial tumors who only presented with positional vertigo to avoid misdiagnosing the disease.
UNASSIGNED: Six patients with intracranial tumors who only presented with positional vertigo treated in our clinic between May 2015 to May 2019 were reviewed, and the clinical symptoms, features of nystagmus, imaging presentation, and final diagnosis of the patients were evaluated.
UNASSIGNED: All patients presented with positional vertigo and positional nystagmus induced by the changes in head position or posture, including one
case with downbeating nystagmus in a positional test, two cases with left-beating nystagmus, one
case with apogeotropic nystagmus in a roll test, one
case with right-beating nystagmus, and one
case with left-beating and upbeating nystagmus. Brain MRI showed the regions of the tumors were in the vermis of the cerebellum, the fourth ventricle, the lateral ventricle, and the cerebellar hemisphere.
