The patient had a longstanding history of petrous bone cholesteatoma (PBC) on\u00a0the left side and had undergone multiple surgeries to address it. Computed tomography (CT) revealed a radiolucent lesion with bony destruction\u00a0in the left petrous apex. Magnetic resonance imaging of the lesion revealed a hypointense area on T1-weighted images and a hyperintense\u00a0area on T2-weighted and abnormal diffusion-weighted images. A diagnosis of recurrent petrous apex cholesteatoma was made. The patient was\u00a0treated by exteriorization using an endoscopic endonasal approach. The patient is in remission and doing well. The ideal treatment of PBC is\u00a0complete excision, though exteriorization using an endoscopic endonasal approach is considered a second option when excision is not possible.\n\nCite this article as: Nishida N, Fujiwara T, Satoshi S, et al.
