Spontaneous intra-parotid pseudoaneurysm of the external carotid artery: A rare case report due to an unfrequent disease.

Spontaneous intra-parotid pseudoaneurysm of the external carotid artery are very rare, only one case has been reported in the literature until 2019. The authors describe the second rare case of a spontaneous pseudoaneurysm of the external carotid artery which mimicked a parotid neoplasm in a young patient with pulsatile and non-fixed mass. The clinical presentation, diagnosis, and management of this condition are discussed. We report a new etiology of this rare entity that should be considered in the differential diagnosis of an atypical parotid mass.
