Central skull base osteomyelitis due to nasopharyngeal Klebsiella infection

Skull base osteomyelitis (SBO) is a rare but life-threatening disease usually seen as a complication of otitis externa [1]. It initially involves the lateral part of the temporal bone and extends to the petrous apex and clivus [2], accompanied by bone erosion, thrombophlebitis, and hematogenous seeding [3]. Thus, patients with SBO typically present with otalgia, otorrhea, hearing loss, and cranial nerve dysfunction in the immunocompromised, particularly older diabetic patients [4].
