Note:—Clinical & imaging features are displayed according to location. Clinical features are shown in bold; imaging findings are seen in the portion to the right. TT indicates tegmen tympani; JF, jugular foramen; IAC, internal auditory canal; CPA, cerebellopontine angle; MCF, middle cranial fossa; CHL, conductive hearing loss; SNHL, sensorineural hearing loss; TH, trabecular hyperostosis; RT, retrotympanic; Nystag, nystagmus; Tinn, tinnitus; Vest Sx, Vestibular symptoms; Perm –Scler, permeative –sclerotic; Min, minimal; U, unknown; CT Oss, presence of ossicular abutment or encasement by soft tissue; CT Facial Canal, presence of bony facial canal encroachment by hyperostosis; Ca++, calcification; M, male; F, female; Assoc, associated; N, nerve; +, positive features; –, absent findings.
