2022-10-29 08:48:02 A 65-year-old man is brought to the emergency department after having a seizure. Past medical history is significant for non-small cell lung carcinoma diagnosed 2 years ago and treated surgically. He continues to work as a college professor and usually walks 1-2 miles daily. MRI of the brain shows a solitary cortical mass (2 cm x 3.5 cm) in the right hemisphere at the grey-white matter junction that is most consistent with metastasis. CT scan of the chest and abdomen shows no evidence of recurrent malignancy. The patient is admitted for further management and started on phenytoin. Open / Comment

2022-10-28 20:47:01 Educational objective: Phenytoin is an antiepileptic drug with known teratogenic effects (eg, fetal hydantoin syndrome). Women of childbearing age who have a low risk of seizure recurrence may safely discontinue phenytoin if considering becoming pregnant; however, the medication should be slowly tapered as rapid withdrawal may result in seizure recurrence.
