title: [Atypical osteomyelitis of the base of the skull and malignant otitis externa].
abstract: Osteomyelitis of the skull base is a rare, but serious disease whose incidence is tending to increase. It affects the marrow of the temporal, occipital and sphenoid bones and is generally secondary to Pseudomonas aeruginosa infection of the external auditory meatus. Based on a clinical case, the authors recall the difficulty of establishing the positive diagnosis and the possible confusion with neoplastic disease, hence the fundamental role of biopsies. They also review the literature on this subject.
