Abstract

Purpose: To evaluate the clinical implications of status epilepticus in patients with metastases to the brain as well as associated demographic, clinical, EEG and radiographic features. Methods: Retrospective chart review of 19 patients with metastases to the brain who subsequently developed status epilepticus. Results: Of the patients who developed status epilepticus only 36.8% had a prior history of seizures since diagnosis of brain metastases. Status epilepticus most commonly occurred in the setting of a new structural injury to the brain such as new metastases, increase in size of metastases or hemorrhage. 57.9% of patients had either refractory or super-refractory status epilepticus. Focal non-convulsive status epilepticus was the most common subtype occurring in 42.1% of patients. 31.6% of patients died within 30 days of the onset of status epilepticus. Conclusion: Status epilepticus eventually resolved with treatment in all patients with brain metastases; however, it is associated with poor outcomes as nearly one-third was deceased within 30-days of onset. Nevertheless, no patients died during status epilepticus. Thus, status epilepticus may be indicative of an overall poor clinical status among patients with brain metastases.
