| ABSTRACT |
|
A retrospective analysis by chart review of consecutive 140 patients with vertigo who visited emergency department of Severance hospital from Jan 1994 to Jun 1996. All patients underwent cranial computed tomography to rule out intracranial lesion at the time of initial visit. The purpose of this study is to determine which clinical parameters can be used to select patients with vertigo requiring cranial computed tomography (CT) scan.
The results were as follows ;
1. Twenty-two patients (15.7%) had positive CT scans.
2. There are no significant correlation between CT result and history of hypertension, previous cerebrovascular accident, nausea, vomiting, headache, tinnitus, nystagmus, Nylen-Barany test.
3. A statistical correlation existed between CT outcome and clinical variables on neurologic examination - motor and sensory deficit, diplopia, tandem gait, Romberg test, finger to nose test.
4. Patients with neurologic abnormality had an increased risk of a CT abnormality (51.2%).
Our data suggest that the patient with vertigo who had neurologic abnormality should perform brain CT scan to rule out intracranial lesion, but a prospective study is required to confirm our results.
