1 Mural cholesteatoma. Mural cholesteatoma. Axial (A) and coronal (B) HRCT scans show the shell of the cholesteatoma in the epitympanum (black arrow) and the automastoidectomy cavity (thick arrow) without a history of surgery. Note the complete erosion of the ossicles, the fistula of the horizontal semicircular canal (dashed black arrow), and the wall erosion of the tympanic segment of the facial nerve canal (white arrow).
