Parry-Romberg syndrome: conventional and advanced MRI follow-up in a boy.

We studied a 9-year-old boy, affected with the Parry-Romberg syndrome, during a period of 32 months, by means of clinical evaluations and neuroradiological magnetic resonance imaging. Over this time we observed a clinical progression of the cutaneous disease without a simultaneous progression of the neurological alterations. Conventional and advanced magnetic resonance imaging techniques showed white matter alterations which proved to be stable during the follow-up.
