ABSTRACT
Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory demyelinating disease of the central nervous system, usually occurring after a vaccination or infectious disease. It has been exceptionally described in transplanted patients. The pathophysiology remains incompletely understood. We report the clinical, biological and magnetic resonance imaging (MRI) presentation and evolution of two kidney-transplanted patients with ADEM associated with local Epstein-Barr virus (EBV) reactivation. ADEM may occur in transplanted patients with favorable evolution. Its pathophysiology is uncertain, and the implication of EBV is discussed.

INTRODUCTION: Behçet's disease is a multi-system vascular-inflammatory disease with possible involvement of the central nervous system. Lesions of the corpus callosum on MRI have been rarely reported in this disease. CASE REPORT: A 47-year-old woman was admitted for a sudden right hemiplegia and confusion revealing a Behcet's disease. MRI showed a pedonculo-thalamic lesion and a white matter hypersignals, which was suggestive of the disease. Besides, involvement of the corpus callosum was observed. CONCLUSION: This case demonstrates that Behcet's disease should be considered among diseases with corpus callosum involvement.
