The CT appearances of cytomegalovirus pneumonitis after kidney transplant

Objective To improve the CT diagnosis in cytomegalovirus pneumonia after kidney transplant. Methods The CT appearances of 7 patients with cytomega- lovirus prceumonitis after kidney transplant were retrospectively analyzed. 5 patients were performed CT plain scan, and 2 patients were performed CT plain scan and en- hanced 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 inter- lobular (n=3) and bronchiectasis (n=1). Conclusion There are characteristic features of cytomegalovirus pneumonitis after kidney transplant on CT. CT plays an important role in the diagnosis of the disease.
