We describe the clinical and radiological finding in a 57-year-old male with dilated petrosquamosal sinus, mastoid emissary vein, and external jugular vein on the right side; presented with pulsatile tinntus for three years and associated with vertigo and mild hearing loss in the right ear with normal clinical examination. Audiological assessment revealed mild sensorineural hearing loss in the right ear and normal tympanogram. Computed tomography scan with contrast show dilated petrosquamosal sinus, mastoid emissary vein, and external jugular vein on the right side showing the relationship between this abnormality and pulsatile tinntus, vertigo, and sensorineural hearing loss as one of differentials and its surgical importance in ear surgery as the first case to be reported with this combination of anomalies.
