A reddish pulsatile mass beyond tympanic membrane: think before act.

We report a case of a 76-year-old man that referred to our hospital because of progressive mixed right hearing loss, aural fullness and pulsatile tinnitus synchronized with heart beats. Otoscopic examination revealed a reddish pulsatile mass beyond tympanic membrane. CT and MRI scans showed a class C glomus tumor. Anamnesis and a complete physical examination, with careful differential diagnosis, should be obtained to rule out highly vascularized middle ear lesion before any invasive procedure.
