  ABSTRACT: Cholesteatoma is a fairly otologic common problem. However, cholesteatoma invading the internal auditory canal (IAC) is rare and typically results in profound hearing loss and facial paralysis. This is a case of a 46-year-old female with a history of prior right complex cholesteatoma that had undergone multiple procedures. She had multiple complications including right cerebral spinal fluid (CSF) leak, meningitis, recurrent mastoid bowl infections and right facial paralysis which resulted in multiple facial plastics procedures and overclosure of the right ear. Over the last three years, she has noticed an increase in right sided otalgia, facial pressure, facial numbness and headaches. An MRI temporal bone with diffusion weighted imaging (DWI) showed a DW positive soft tissue mass filling the mastoid bowl as well as extending into the IAC and cerebellar pontine angle (CPA) cistern with contact of the middle cerebellar peduncle and trigeminal nerve. A translabyrinthine approach to the IAC found the mastoid bowl to be filled with cholesteatoma and an osseous defect from the mastoid bowl along the labyrinthine facial nerve tracking cholesteatoma into the IAC/CPA. This case highlights the complex and aggressive nature a cholesteatoma can take and the need for diligent surveillance in any ear that had prior cholesteatoma. The utilizations of MRI temporal bone with diffusion weighted imaging allow for surveillance in an over closed ear canal that is vital to the care of cholesteatoma patients who have a similar history.
