title: [The misleading blue tympanic membrane. Prolapse of the internal jugular vein].
abstract: The authors report a case of a jugular bulb dehiscence extending to the tympanic cavity. They alert that the finding of a blue mass in the middle ear should evok the possibility of a vascular variant or abnormalitie. High resolution CT is extremely helpful in the correct diagnosis by showing the subtle and characteristic bone changes.
