MR Angiography Imaging of Absence Vertebral Artery Causing of Pulsatile Tinnitus: A Case Report
ثبت نشده
چکیده
Absence of the vertebral artery is rare, and incidentally encountered in radiological imaging technics. We reported a 74 years old man suffering from pulsatile tinnitus with absence of the left vertebral artery. The purpose of the case report is the description absence of the vertebral artery causing of pulsatile tinnitus, in order to offer useful data to anatomists, otorhinolaryngologist, radiologists, vascular, head and neck surgeons.

MR angiography of an aberrant internal carotid artery.
Pulsatile tinnitus with or without a vascular-appearing retrotympanic mass has a number of possible causes (1]. Previous reports (1-4] have stressed the use of CT for evaluation when the masses are vascular appearing. In addition, Remley et al. [1] concluded that MR imaging has only a secondary role in the evaluation of pulsatile tinnitus because it cannot detect vascular variants such as an ab...
متن کاملPulsatile tinnitus: a symptom of chronic subclavian artery occlusion.
We report the unusual case of pulsatile tinnitus caused by muscular branches of the occipital artery, which developed to supply the distal vertebral artery after subclavian artery occlusion. Anatomical findings and options of endovascular treatment are discussed. To our knowledge, subclavian artery occlusion causing an objective tinnitus has not been reported.

PURPOSE 1) To evaluate the scope of imaging findings seen with spin-echo MR and MR angiography (MRA) in patients with pulsatile tinnitus; 2) to determine whether MRA adds additional imaging information (to that provided by spin-echo MR) necessary for determining the cause of pulsatile tinnitus; and 3) to suggest MR and MRA imaging techniques for evaluation of patients with pulsatile tinnitus. ...
متن کاملPersistent Primitive Trigeminal Artery: An Unusual Cause of Vascular Tinnitus
Pulsatile tinnitus is generally of vascular origin and can be due to arterial, venous, or systemic causes. While certain congenital anatomical variants and arterial vascular loops have been commonly found in symptomatic patients undergoing imaging, persistent primitive trigeminal artery in association with isolated tinnitus is unusual. Thus we report a patient with unilateral isolated pulsatile...

OBJECTIVES/HYPOTHESIS Pulsatile tinnitus in the face of normal findings on otoscopy is a common otological diagnostic dilemma and can be due to serious vascular malformations such as transverse or sigmoid sinus dural arteriovenous fistula (transverse or sigmoid sinus [TS] DAVF). Left untreated, TS DAVF may result in significant morbidity and mortality. TS DAVF can be suspected or diagnosed with...
