Hydrocephalus as a rare compilation of vertebrobasilar dolichoectasia: A case report and review of the literature

BACKGROUND: Vertebrobasilar dolichoectasia (VBD) is a rare disease characterized by significant expansion, elongation, and tortuosity of the vertebrobasilar arteries. Hydrocephalus is a rare compilation of VBD. CASE DESCRIPTION: In this study, we report a 68-year-old male presenting with headache, progressive decreased visual acuity, memory loss, imbalance while walking, and episodes of urinary incontinency. The patient was diagnosed with dolichoectasia of basilar artery causing compression of the third ventricular outflow and thus, presenting with hydrocephalus documented with brain computed tomography scan and brain magnetic resonance imaging. The patient underwent surgical operation and ventriculoperitoneal shunt placement. CONCLUSION: In the case of hydrocephalus or normal pressure hydrocephalous, VBD should be considered as a differential diagnosis.
