[Parry-Romberg's syndrome and epilepsy]. / Syndrome de Parry-Romberg et épilepsie.

INTRODUCTION: Parry-Romberg's syndrome or progressive facial hemiatrophy is a rare disorder of unknown etiology which may be accompanied by neurological complications, frequently epilepsy, usually focal refractory epilepsy. The associated brain lesions are located on the same side as the half face atrophy and may progress. OBSERVATION: We report the cases of two patients with Parry-Romberg's syndrome and epilepsy. Neurosurgery was performed in one patient, enabling a histological study. CONCLUSION: The link between Parry-Romberg's syndrome and epilepsy is discussed and the neurodevelopmental theory with vascular dysgenesis is suggested.
