A Novel Case of Providencia rettgeri Osteomyelitis Presenting in the Frontal Bone.

Osteomyelitis of the skull is a particularly life-threatening condition. Infections are usually at the base of the skull and typically occur following dissemination from another site, such as the external auditory canal. Typical organisms include Pseudomonas and Staphylococcus species. This paper demonstrates an unusual case of osteomyelitis of the frontoparietal bone, as well as the first published case of Providencia rettgeri causing cranial osteomyelitis in humans.
