Clinical findings: otoscopic examination, using a rigid endoscope 0  (Figure 1), revealed a red pulsatile swelling behind the lower part of the right ear-drum.
temporal bones computerized tomography (CT), coronal (A) and axial (B) sections, without contrast, showing a nonspecific, well-defined, 7 mm right nodular mass of soft tissue, arising from the hypotympanum and overlying the cochlear promontory

Temporal bones Computerized tomography (CT), axial and coronal sections, without contrast, showed a nonspecific, well-defined, 7 mm right nodular mass of soft tissue, arising from the hypotympanum and overlying the cochlear promontory (Figure 2).
MRI showing a 15 mm mass of the right tympanic cavity, with a "salt and pepper" pattern of hypo intensity and hyper intensity on T1-weighted images (A), relatively higher in intensity on T2-weighted images (B), and strongly enhanced after gadolinium injection (C)

MRI showed a 15 mm mass of the right tympanic cavity, with a "salt and pepper" pattern of hypo intensity and hyper intensity on T1-weighted images, relatively higher in intensity on T2-weighted images, and strongly enhanced after gadolinium injection (Figure 3).

MRI was completed with angio-MRI sequences showing a hyper vascular lesion corresponding to the glomus tympanicum tumor (Figure 4).
per-operative view: the tumor was hyper vascular, easily bleeding, emerging from the hypotympanum, filling the tympanic cavity and occluding the Eustachian tube

On per-operative examination, the tumor was hyper vascular, easily bleeding, emerging from the hypotympanum, filling the tympanic cavity and occluding the Eustachian tube (Figure 5).

The lesion was totally excised (Figure 6, Figure 7) without mastoidectomy which was judged unnecessary.
