[Post-transplant lymphoproliferative disorder is a rare cause of spinal cord compression].

A 74-year-old man presented with sensory deficits and lower limb weakness four years after a renal transplant. MRI showed an intramedullary mass at the T5 level. Following surgical excision the diagnosis post-transplant lymphoproliferative disorder (PTLD) was made. Although the frequency of PTLD is low in kidney transplant recipients (≤ 1%), it is an important differential diagnosis in a patient with new-onset neurological deficits following solid-organ transplantation.
