Fig. 1. Axial high-resolution CT at the level of the lateral semicircular canal shows a nodular attical soft tissue lesion (white arrow) with erosion of the anterior limb of the lateral semicircular canal (black arrow), highly suggestive of a cholesteatoma with erosion of the anterior limb of the lateral semicircular canal. Note the loss of delineation of the body and short process of the incus suggesting an extensive erosion (small arrow).
