Cytomegalovirus (CMV) infection is a significant cause of morbidity and mortality after solid organ transplantation. There has been a significant shift in disease epidemiology with the introduction of antiviral prophylaxis, with CMV disease occurring later and clinical presentations more atypical. We describe two cases of very late-onset CMV disease where first disease occurred 15 and 18 years post-renal transplantation, with both cases complicated by antiviral drug resistance. We subsequently review the published cases and literature of very late-onset CMV disease (onset > 10 years post-solid organ transplantation) as an increasingly recognized phenomenon which is emerging as an important aspect in improving long-term patient outcomes in the current era of renal transplantation.
