title: Extradural haematoma secondary to chronic sinusitis: a case report.
abstract: The complications of frontal sinusitis are well-known. There is no record in the medical literature of an extradural haemorrhage resulting from pathology of the frontal sinus. I report a case of chronic frontal sinusitis with polyposis, resulting in an extradural haematoma.
