Intracranial infection caused by spreading through the fossa naviclaris magna - a case report and review of the literature.

Fossa navicularis magna is a congenital anomaly representing persistent dehiscence of the basiocciput. This tract from the nasopharynx to the brain is common and carries a potential risk for infection. Nevertheless reports on such dissemination are very rare. We present a child with brain infection via a fossa navicularis magna, the first description to our knowledge, and review the literature on this anomaly.
