Diffuse large B-cell lymphoma (DLBCL) was the most frequent subtype of lymphoid malignancy. Corpus callosum involvement of DLBCL was rarely reported. We present a case of DLBCL involving not only lymph nodes and bowels but also corpus callosum, detected by FDG PET/CT in a patient without neurological symptoms. After 4 cycles of systemic and intrathecal chemotherapy, all previously visualized abnormal activity disappeared on the follow-up FDG PET/CT.
