Two cases of pulsatile tinnitus: Key points for the clinician
Introduction:
Pulsatile tinnitus is a sound generated by an acoustic source from within the body, which is perceived by the auditory system of the patient.
Cases Summary:
We report two puzzling cases of pulsatile tinnitus with normal ENT examinations: the first was due to a cervical internal carotid artery dissection, and the second to the compression of the foramina of Monro by a craniopharyngioma, leading to hydrocephalus.
Discussion:
We review the systematic management and emphasize the decisive role of the ENT clinician regarding this pulsatile tinnitus complaint, because of the potentially severe complications of its underlying pathology.
