HYPERDENSE BASILAR ARTERY – EARLY SIGN OF STROKE
Keywords:
basilar artery, hyperdense, posterior circulation stroke
Abstract
Hyperdense artery sign is presumed to represent acute thrombus or clot, and is an early indicator of posterior circulation stroke. This sign if detected, in proper clinical scenario can help the clinician to detect the basilar occlusion and to intervene early. We are presenting a case of 30 yr. old female, normotensive, nondiabetic presented with sudden onset focal left sided seizure, central vertigo, diplopia and decreased vision in left eye to emergency department. On examination, ptosis and anisocoria, Left facial nerve palsy. Patient was advised NCCT Head, which showed hyperdense basilar artery , seen retrospectively after MRI.
