Figure 2

MRI of the brain, IAC, and mastoid with IV contrast. Axial and coronal views show (a) MRI T1 axial view before contrast, (b, c) MRI T1 axial view after contrast, and (d) MRI T1 coronal view after contrast. Right, large, loculated, peripheral enhancing collection is observed in the subcutaneous tissue of the auricular region, posterior and anterosuperior to the external auditory canal and extending to the mastoid air cells and middle ear cavity. The cochlea and semicircular canals are not visualized; only part of the vestibule is observed, and a focal area of dural enhancement is observed in the right temporal lobe.
