There are multiple described causes of this syndrome, mainly severe arterial hypertension, renal insufficiency, sepsis, preeclampsia or eclampsia, immunosuppressive therapy and others. We report a case of a 38-year-old man, renal post-transplant in treatment with mycophenolate and prednisone, with renal failure of the transplant and chronic anemia, hospitalized by urinary focus sepsis plus lymph node tuberculosis, who after receiving 1 concentrate of red blood cells presents seizures, Hb elevation of 3.1 g/dl and images compatible with vasogenic edema and almost complete resolution of them at 16 days.
