Subdural empyema secondary to odontogenic masticator space abscess: detection by indium-111-labeled white cell scan.

Subdural empyema (SDE) is an extremely rare but serious complication of dental infection. A case is presented in which dental infection was complicated by a masticator space abscess and eventually led to a SDE. This report illustrates a rare sequence of events leading to SDE and its serendipitous detection by indium-111-labeled leucocyte scan.
