Case 3: Type-II in non-cholesteatomatous CSOM. Type-II (pyramidal) is seen in a, and Köerner septum is seen in b, at the lateral margin of the opacified mastoid antrum. Curved multiplanar reformats reveal ossicular–V sign of intact incus body and process (This means the V-shaped appearance of the intact continuous incudo-stapedial junction is most susceptible to erosions). The stapes is well visualized in d with intact incudo-stapedial junction
