Fronto‐polar epilepsy masquerading as juvenile myoclonic epilepsy

A woman diagnosed with juvenile myoclonic epilepsy for over 30 years presented with stereotyped episodes of abnormal sensations in both arms. Continuous video-EEG monitoring for 14 days and MRI brain revealed that the patient's somatosensory events with associated postictal aphasia, as well as her myoclonic and generalised tonic-clonic seizures, were likely due to a symptomatic left fronto-polar epilepsy. Our case emphasizes the need for clinicians to consider fronto-polar epilepsy as a potential cause of myoclonic seizures, particularly when associated with other semiologic features suggestive of frontal lobe epilepsy.
