Abstract:
Purpose:To evaluate the efficacy of early neuroimaging in patients with acute isolated 3rd, 4th, and 6th nerve palsy.
Methods:Neuroimaging tests were performed in patients >50 years old with acute isolated 3rd, 4th, and 6th nerve palsy. The frequencies and types of abnormal findings were evaluated. All patients were divided into ischemic and non-ischemic groups and differences in clinical characteristics between groups were analyzed.
Results:Of the 55 patients, nine (16.4%) had abnormal findings on brain imaging. Among 26 patients with 6th nerve palsy, four (15.4%) were found to have a cause including brain tumor, cerebrovascular compression, carotid cavernous fistula. Superior oblique muscle atrophy was found in two of 19 patients (10.5%) with 4th nerve palsy. Three of 10 patients (30%) with 3rd nerve palsy had abnormal findings and there were cases of pituitary apoplexy, posterior communicating, and cerebrovascular compression.
Conclusions:In patients with acute isolated oculomotor paralysis, early neuroimaging tests play an important role in differential diagnosis and evaluation of causes that may lead to mortality.
