Jugular bulb diverticula.
Jugular bulb diverticula may extend either laterally in the tympanic cavity or medially towards the petrous pyramid close to the inner ear. In the first case, this leads to subjective symptoms related to the presence of a mass at the level of the tympanic cavity and the external auditory canal and thus to conductive hearing loss and pulsatile tinnitus. In the second case, vertigo, pulsatile tinnitus and sensorineural hearing loss occur. 4 cases of jugular bulb diverticula are described (1 medial type, 3 lateral type).
