Purpose :
Pulsatile tinnitus (PT) is an auditory phenomenon that occurs in the absence of an external stimulus and presents as a humming or whooshing sound synchronous with the subject’s heartbeat. Although pulsatile tinnitus can be audible, objective demonstration of this heartbeat-synchronous sound has rarely been successful. Pulsatile Tinnitus is one of the least understood and most frequently underdiagnosed vascular symptoms. The constant, pulse-synchronous sound can be both alarming and profoundly disturbing. Identification of the underlying cause of pulsatile tinnitus is important for treatment decision making and for prognosis estimation. For this, an adequate diagnostic imaging strategy is crucial.
Materials & Methods :
We report a 39-year-old female patient complaining of pain in the right ear accompanied by ears ringing and hearing like a heartbeat since 5 months ago. Complaints are felt continuously, accompanied by spinning dizziness and decreased hearing since 2 years ago to the present. General physical examination did not show any significant findings. Further examination was attended to make an accurate diagnosis, included endoscopy examination revealed a bluish pulsatile rounded swelling about 2 cm in diameter both on the medial and lateral aspects of the lobule of the right ear, sensorineural audiometry with heavy degree hearing loss, x ray schuller and stenver showed normal, CT scan was found Inhomogeneous isodens lesions in the right mastoid region extend to the right tympanic cavity which obliterated in the antero superior direction m. right temporal, m. right pterygoid, m. right masseter, to the postero inferior to the os. greater sphenoid wing right urges a. right internal carotid and infiltrate the right cerebellum.
Results :
DSA examination shows a picture of the venous malformation with the nidus in the right auricular region that feeds the arteries from the right posterior auricular artery branch by draining the vein to the right internal jugular vein region.
Conclusions :
Radiological imaging has a major role in the diagnosis of arteriovenous malformation with pulsatile tinnitus at the right mastoid, so it will help in the selection of management quickly and precisely.
