case_images: Brain enhanced magnetic resonance imaging showed lymphoma in the right temporal lobe and frontal lobe, accompanied by peripheral cerebral edema and right subfalcine herniation ( Figure 1 ).
case_images: The patient underwent peripheral blood mononuclear cell and plasma collection on d-10 and received conditioning regimen before HSC infusion on do. Two separate CAR T-cell products (CD22 and CD19 CAR T-cells) were infused within the range of 3-4 days (d+3 to d+4) after HSC infusion.
