Objective To investigate the clinical features of vertebrobasilar dilatation (VBD) in order to improve the understanding of VBD. Methods The clinical and imaging data of 5 patients with VBD were retrospectively analyzed. Results CTCT and MSCT were confirmed in 2 patients and MRA in 3 patients. Both of them were diagnosed according to the above diagnostic criteria. All patients had dizzy symptoms, 1 case of limb weakness, 1 case of diplopia, 1 case of trigeminal neuralgia, 1 case of left hemifacial spasm and mild facial paralysis, 1 case of tinnitus and hearing loss. Previous history of stroke in 1 case, transient ischemic attack (TIA) in 1 case, 2 cases of hypertension, hyperlipidemia in 3 cases, 1 case of diabetes. Conclusion VBD is easy to misdiagnosis, improve the diagnostic rate, is beneficial to the treatment of patients and improve the prognosis.
