Abstract
Computed tomographic scanning of the petrous bone and magnetic resonance imaging sequences of the inner ear and cerebellopontine angle of a deaf patient were performed to find an explanation for his deafness, and to establish whether he would be a good candidate for cochlear implantation. The imaging features were considered pathognomonic for incomplete partition type III (IP type III). Further management and discussion of this deafness subtype are detailed.

Computed tomographic (CT) scanning of the petrous bone and magnetic resonance imaging (MRI) sequences of the inner ear and cerebellopontine angle of a deaf patient were performed to find an explanation for his deafness, and to establish whether he would be a good candidate for cochlear implantation
The combination of clinical and imaging findings in this patient are characteristic of IP typeIII, which is often referred to as X-linked deafness type 2 (DFNX2).[1,2,3,4,5,6,7,8,9]
