Abstract
INTRODUCTION
Approximately 20% of ischemic events are
known to involve the neural structures supplied
by the posterior (vertebrobasilar) circulation, and
dizziness/vertigo is one of the most common
symptoms of vertebrobasilar diseases [1]. In cerebrovascular
disorders, the dizziness/vertigo usually
accompanies other neurological symptoms and
signs. Indeed, medical adage had taught us that
isolated vertigo mostly comes from peripheral
vestibular diseases. However, isolated vascular
vertigo might have been underestimated. With
recent developments in clinical neurotology and
neuroimaging, diagnosis of isolated vertigo from
brainstem and cerebellar strokes has increased
markedly (Fig. 1). Furthermore, transient isolated
vertigo is the common manifestation of vertebrobasilar
insufficiency [2].
It is important to differentiate isolated vertigo
of a vascular cause from more benign disorders
involving the inner ear since therapeutic strategy
and prognosis differ in these two conditions.
Misdiagnosis of acute stroke may result in significant
morbidity and mortality, whereas overdiagnosis
of vascular vertigo would lead to unnecessary
costly work-ups and medication.
