Two cases of pulsatile tinnitus: Key points for the clinician.

Pulsatile tinnitus is a sound generated by an acoustic source from within the body, which is perceived by the auditory system of the patient. 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. 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.

Pulsatile tinnitus and carotid artery dissection.

Carotid artery dissection is an uncommon entity associated with head and neck pain, partial Horner's syndrome, amaurosis fugax, and brain ischemia, which may all occur in isolation or in combination. Herein, we report a rare case of cervical artery dissection in which pulsatile tinnitus was the only reported symptom. A 38-years-old man attended our hospital with a 4-days history of left side pulsatile tinnitus which began after stumbling. He had no other symptom. MRA showed luminal stenosis with pseudo lumen of the internal carotid artery. The patient was diagnosed with left internal carotid artery dissection and treated with antihypertensive therapy accordingly. After 2 months, the stenosis and tinnitus spontaneously resolved.
