Parry-Romberg syndrome presenting as status migrainosus.

Parry-Romberg is a rare syndrome of unknown origin, characterized by hemiatrophy of the face including subcutaneous tissue, skeletal muscle, and bones, along with various ocular and central nervous system abnormalities. Some investigators consider that injury to the sympathetic fibers of the trigeminal nerve is a cause for evolution of this syndrome. Various central nervous system symptoms have been reported in correlation with the syndrome, including epilepsy and hemiparesis.
