ABSTRACT

Background: Central skull osteomyelitis is a rare, life-threatening complication of necrotizing or malignant external otitis, which results in destruction of the skull base. The imaging appearances can be misinterpreted as a malignancy, so it is important the consideration of this diagnosis, both radiologically and clinically, supported by the biopsy and culture trying to avoid the extended and aggressive surgical treatment because of their risks.
Clinical cases: This paper reports the findings of the CT scan, MRI and nuclear scan with Tc99, also we did an endoscopic biopsy and culture of the nasopharynx and adjacent tissue in two cases and a microscopic biopsy and culture of the ear in one of them.
Conclusions: Osteomyelitis of the central skull base generally affects men over 50 years of age, its onset is with headache and predominantly lower cranial nerves.
