Background:
Symptomatic hydrocephalus due to vertebrobasilar dolichoectasia is a rare occurrence.
Case description:
We report a patient who presented with acute confusion and vomiting. Neuroimaging revealed elongated and tortuous basilar artery indenting and elevating the floor of third ventricle causing obstructive hydrocephalus. Initially, the patient was treated with external ventricular drain and then with ventriculo-peritoneal shunt.
Conclusion:
We suggest prompt surgical intervention upon diagnosis as a first choice of treatment in order to avoid further complications.
