Delayed absence seizure: A complication of intrathecal fluorescein injection

Intrathecal fluorescein injection has a long history of use by surgeons to determine the exact site of a cerebrospinal fluid (CSF) leak from the skull base. This method, however accurate, is not without complications. We present a case of grand mal and absence seizure after intrathecal fluorescein injection and discuss the possible aetiological factors. We also review the articles in the diagnostic methods for the CSF rhinorrhoea and the complications of the intrathecal fluorescein injection.
