A case of frontal lobe seizures with 'dancing‐like' semiology.

Background and purpose: 'Dancing‐like' semiology is extremely rare and described in few case reports. It is characterized by rhythmic, oscillatory movements of the pelvis and/or limbs during which the subject appears to be dancing. It has been associated with both the frontal and temporal epileptic zone; however, the possible network involved in these fascinating seizures is unclear. Methods: The case of a 45‐year‐old woman suffering from drug‐resistant focal epilepsy with multi‐day seizures of bizarre semiology is described. A structural and perfusion magnetic resonance imaging study (interictal and peri‐ictal) and video‐electroencephalograms were carried out, and several home videos were employed. A vagal stimulator was implanted. Results: Home videos documented the 'dancing' semiology of seizures better than video‐ electroencephalogram recordings. The imaging study revealed a focal frontal polymicrogyria with a peri‐ictal cerebral blood flow increase at the perisylvian lesion foci. The combination of add‐on cenobamate and vagal nerve stimulation resulted in complete seizure freedom. Conclusion: The unusual and complex dancing‐like semiology observed during our patient's seizures adds to the repertoire of fascinating complex motor manifestations of frontal lobe epilepsy.
