Methods The CT appearances of 7 patients with cytomegalovirus prceumonitis after kidney transplant were retrospectively analyzed. 5 patients were performed CT plain scan, and 2 patients were performed CT plain scan and enhanced scan. Results The most frequent CT appearance was ground glass opacity which was seen in 6 cases. Consolidation was seen in 3 cases and small multiple nodules in 4 cases. The other CT manifestations included pleural effusion （n=4）, thickened interlobular （n=3） and bronchiectasis （n=1）.
