Chronic extradural hematoma: case report.

A recent experience with a chronic extradural hematoma found unexpectedly during an evaluation for an enlarged sella turcica is reported. This case, as well as pertinent literature, demonstrates the variability of the classical signs in the chronic lesion. Our experience suggests that the diagnosis of patients with persistent symptoms after head injury may be clarified by computerized tomographic scanning, which in the present case revealed chronic extradural hematoma.
