Prolonged course of osteomyelitis of the frontal bone with a combined rhinogenic orbital and intracranial complication

Osteomyelitis of the skull bones is a very rare disease. Usually, the bones of the cranial vault are affected a second time by spreading infection through the veins and lymphatic vessels from neighboring foci - mainly from the paranasal sinuses, much less often from the middle ear. The frontal, temporal and parietal bones are most often affected. In most cases, osteomyelitis of the skull causes intracranial complications.
