We report a case of acute lymphoblastic leukemia (ALL) with ocular involvement in which bilateral swelling of the optic disk head was noticed. Massive direct infiltration of the optic nerve head by leukemic cells can give rise to a clinical picture identical to that of a true papilledema. Ocular echography allowed a better and more complete interpretation of the optic disk involvement. No echographic description of a leukemic infiltration of the optic nerve head has been reported previously.
