Eagel syndrome is a symptom complex with, for example, foreign body sensation or odynophaia caused by a prolonged Proc. styloideus or by an ossified respectively calcified Lig. stylohyoideum. The syndrome is quite common in the normal population with an incidence of 4%. However, only 4% of those affected suffer from symptoms (0.16%).


The 46 year old patient presented himself because of the incidental finding of a proximal occlusion of the right internal carotid artery (ACI) in an MRI of the skull. The MRI was done due to a sudden hearing loss on his left ear. The patient showed no evidence of neurological failure and displayed no Eagel syndrome associated symptoms. There were no laboratory or clinical signs of vasculitis. The cause of ACI dissection on the right side was attributed to a bilateral Eagel syndrome with an elongated Proc. styloideus (5 cm on both sides).


Due to the clinical and imaging asymptomatic occlusion of the right ACI, there is currently no necessity for intervention or monitoring. A possible surgical shortening of the left Proc. styloideus to prevent a dissection of the left ACI was considered in our interdisciplinary basal skull conference. Due to the absence of symptoms, the patient prefers a wait and see attitude.


In this case, an interdisciplinary approach was necessary for the diagnosis and to give therapy recommendations. Even without typical symptoms such as foreign body sensation, Eagle syndrome can lead to severe complications. Surgical therapy from the outside or from enoral is possible and can be considered to prevent further complications.
