Brainstem and facial nerve compression syndromes due to vertebrobasilar dolichoectasia: A case report and literature review

Background: Vertebrobasilar dolichoectasia (VBD) is a rare vasculopathy which is characterized by arterial elongation, dilation, and tortuosity. Current data regarding VBD are very limited. We present a case of VBD with brainstem compression syndrome and facial nerve palsy. Case presentation: A 62-year-old Chinese male initially presented with left peripheral facial paralysis, left facial hypoesthesia around the mouth. A clinical diagnosis of vertebrobasilar dolichoectasia was made based on MRI and CTA, which showed an elongated and tortuous left vertebral artery. These symptoms partially improved following corticosteroids therapy, multivitamins and symptomatic supportive treatments. Conclusion: Vertebrobasilar dolichoectasia is a very rare cause of brainstem and facial nerve compression, there is no effective treatment of the clinical symptoms. The pathogenesis and therapy of VBD needs further investigation. Keywords: Vertebrobasilar dolichoectasia, Brainstem compression, Facial nerve palsy
