Progressive hemifacial atrophy: report of three cases, including one observed over 43 years, and computed tomographic...

Three cases of progressive hemifacial atrophy were studied. In two patients, abnormalities were noted on the computed tomographic (CT) brain scan, whereas a third patient, with widespread cutaneous and neurologic involvement, had a normal CT scan. Patient 1, first described 44 years ago, had a neurologic disorder with features that have previously been associated with progressive hemifacial atrophy, but that have appeared years after the hemifacial atrophy ceased progression.
