Periodic lateralized epileptiform discharges (PLEDs) may be considered in several cases an epileptic pattern linked to cortical-sub cortical disconnection or to cellular or neurotrasmettitorial modifications. PLEDs can be induced by high dosages of methotrexate (MTX), an antibiotic drug that can cause several types of cerebral lesions. We present a case - a 54 years old man, affected by chronic myeloid leukaemia - in which exposure to single high doses of MTX caused generalized seizures, confusion, and appearance of PLEDs on EEG. In this case, PLEDs could be considered an epileptic pattern, not strictly linked to brain damage and responsive to therapy with sodium valproate.
