From: Vascular tumors of the external auditory canal: three case reports and a review of the literature
Case 1: Enhanced CT scan of temporal bone, axial view a and coronal view b demonstrates a soft-tissue mass (arrow) lateral to the tympanic membrane that fills the right external auditory canal without involvement of the tympanum. There is no evidence of bone erosion, and the tympanic membrane, middle ear, and ossicles appear normal. Magnetic resonance imaging (MRI) of the skull base shows an external auditory canal mass (arrowhead) that is slightly hypointense in a T1-weighted image (c), and hyperintense in T2-weighted images (d).
