Postictal hemifacial purpura.

Non-traumatic stereotyped postictal purpura is rare. A 25-year-old woman presented with right facial, cheek and periorbital purpuric eruptions that occurred after secondarily generalized tonic-clonic seizures. The stereotyped, invariably right-sided facial skin eruption, which resolved in 48 hours, falsely raised concerns of spousal abuse. Possible pathophysiological mechanisms include: (a) valsalva-induced capillary hypertension with secondary purpura, (b) ictal corticolimbic stimulation of the autonomic nervous innervation of facial vasomotor structures, and (c) trigeminal-mediated local release of vasoactive substances. Although rare, such stereotyped patterns of purpura should be recognized to avoid incorrect attribution of spousal abuse.
