For example, in the petrous apex, the cerebellopontine angle, the middle ear cavity, the mastoid process or the external auditory canal. The least common site being the mastoid process. We present two cases of congenital cholesteatoma of the mastoid process, each presenting with different symptoms and at different ages. Both patients underwent surgical treatment, which confirmed the diagnosis and radiological findings.
