¸ñÀû: Vascular lesions are one of the most frequent causes of pulsatile
tinnitus. To make accurate diagnosis and treatment plan,
appropriate imaging studies such as computed tomography (CT),
magnetic resonance imaging (MRI) or angiography is mandatory. In
this study, we aimed to analyze the radiologic findings and
workup modalities in patients with vascular pulsatile tinnitus
and to suggest optimal diagnostic imaging modalities. ¹æ¹ý:Retrospective medical records, radiologic workup and findings were
reviewed in twenty-six patients with vascular pulsatile tinnitus. °á°ú:The spectrum of lesions detected as jugular bulb variants (10/26), sigmoid sinus diverticulum (6/26), dural aterio-venous fistula (4/26), aberrant carotid artery (2/26), some venous variants and internal carotid artery narrowing due to atherosclerosis. Most of them were enough to diagnose with temporal bone CT only after manual neck compression test. Some of other patients who had an arterio-venous fistula or internal carotid artery stenosis were needed more evaluation such as MRI and angiography °á·Ð:After simple manual neck compression test, temporal bone CT only is
enough to diagnose the vascular pulsatile tinnitus for especially
venous origin. So, high suggestion of venous origin pulsatile
tinnitus could be helpful to reduce the unnecessary image workup. |
