Abstract
Objective To explore the causes of misdiagnosis and preventive measures for benign paroxysmal positional vertigo(BPPV).Methods A retrospective analysis was conducted on the clinical data of 6 patients with BPPV that had been misdiagnosed from February 2022 to February 2024.Results Among the 6 patients,1 patient visited the hospital due to paroxysmal dizziness and vertigo accompanied by falls twice,3 patients due to sudden vertigo,and 2 patients due to sudden dizziness.Among them,one patient had cervical disc herniation and cervical osteophyte hyperplasia on cervical spine CT examination.It was misdiagnosed as cercal-origin vertigo.Symptomatic treatment was given,but the dizziness was not significantly relieved.The Dix-Hallpike test was positive,and it was diagnosed as BPPV.After diagnosis,manual reduction and corresponding treatment were given,and the dizziness disappeared.Five patients were misdiagnosed as cerebral artery insufficiency,but after symptomatic treatment,the symptoms were not significantly relieved.Afterwards,based on the medical history and positive postural induction test,BPPV was considered.All of them were given manual reduction and symptomatic treatment,and the symptoms were relieved.The misdiagnosis of 6 patients lasted 1 to 7 d.During the follow-up period of 3 to 4 months,there was no recurrence.Conclusion The manifestations of BPPV are highly similar to those of cervicogenic vertigo and cerebral insufficiency,and it is prone to misdiagnosis.Strengthening the understanding of this disease,improving the collection of medical history and physical examination,rationally applying medical technical examination methods,and carefully making differential diagnoses can increase the early diagnosis rate of this disease.关键词
