A 26-year-old male with paraneoplastic limbic encephalitis presenting with progressive memory disturbance. (a) Initial coronal T2 weighted image demonstrates swelling and increase signal in both mesial temporal lobes (white arrows). (b) Follow-up coronal T2 weighted image after 1 year shows significant decrease in the swelling and abnormal signal intensity (white arrows). (c) Axial contrast-enhanced CT section through the mid-abdomen shows ileocolic intussusception (black arrow) with marked concentric wall thickening of ascending colon (white arrows). Biopsy proven Burkitt's lymphoma of ascending colon is also shown.
