[Thrombosis of the external jugular vein. Case report of a rare cause for pain in the lateral neck]. / Thrombose der vena jugularis externa. Fallbericht einer ungewöhnliche Ursache für Schmerzen im seitlichen Halsbereich.

Dental practitioners are sometimes confronted with patients complaining about pain in the neck area. Especially if an induration in the region of the big vessels is present, one must keep in mind the differential diagnosis of a spontaneous thrombosis of the external jugular vein. This diagnosis needs consequent treatment but also consequent search for an underlying pathology. This case report presents such a situation in an exemplary way.
