This is the first case report of an incidental ipsilateral acoustic neuroma detected during MRI following cholesteatoma surgery. Figure 1: Preoperative high-resolution CT (HRCT; contrast-enhanced axial section) of the temporal bones demonstrating soft tissue opacification in the left medial epitympanic recess, opacification of the left mastoid antrum and air cells, ossicular erosion and bony erosion of the scutum, consistent with a left-sided cholesteatoma. Figure 2: Postoperative MRI (contrast-enhanced T1 axial section) demonstrating 11 mm enhancing mass centred on the left porous acousticus consistent with a left-sided acoustic neuroma.
