AB021. Primary diffuse large B-cell lymphoma of the central nervous system: role of imaging in a rare disease—a case report

Primary diffuse large B-cell lymphoma (DLBCL) of the central nervous system (CNS) constitutes approximately 1-3% of primary CNS tumors. This rare CNS tumor presents diverse clinical manifestations and variable imaging characteristics, making its diagnosis challenging using radiological modalities alone. Recognizing the role of imaging in different stages of treatment and understanding the various imaging patterns and radiological features is crucial for timely diagnosis and appropriate therapeutic decision-making.
