Vascular Anomaly Presenting as Neurological Crisis: A Case Report of Dolichoectasia-Induced Seizures.

A rare brain vasculature illness called dolichoectasia (DE) causes the blood vessels to enlarge and elongate. DE describes an irregular enlargement and dilatation of arteries; this condition primarily affects big blood vessels such as the internal carotid and vertebrobasilar arteries. A range of neurological symptoms may result from this illness because of the compression of nearby structures or changed hemodynamics. Although it is documented more commonly in the vertebrobasilar circulation, rarely it can be seen in the anterior circulation, as in our case. The brainstem structures and cranial nerves are compressed in DE, resulting in turbulent blood flow that causes vertigo and tinnitus and frequently damages the brain's small blood vessels. One risk factor for ischemic stroke is DE. The occurrence of seizures in DE is not so common. Here, we report a case of a 20-year-old female, bioengineering UG with generalized tonic-clonic seizure diagnosed to have DE on MRI.
