Meningeal disease masquerading as transient ischemic attack.

Background: Cortical subarachnoid hemorrhage and meningitis sometimes present as episodes of transient neurologic dysfunction mimicking transient ischemic attack (TIA). In the present study, we sought to determine the frequency of meningeal disease among patients treated in a TIA clinic.

Methods: Data from patients consecutively admitted to a TIA clinic were retrospectively analyzed.
