RESUMO
Objective To make a futher understanding of the CT features of primary carcinoma of vagina and to explore the clinical value of CT diagnosis of it.Methods Sixteen cases of primary cacinoma of vagina with clinical and CT data confirmed by pathology were analyzed retrospectively. The CT findings were observed in a double blind method by three experienced radiologists together and formed a consensus interpretation. Results The accurate rate of CT diagnosis for primary carcinoma of vagina was 81.3% in the 16 cases. There were 2 stage I, 6 stage II, 4 stage III and 4 stage IV lesions which were diagnosed by CT. The numbers of cases of the elevated type, ulcerative type and infiltrative type were 11, 3, and 2,respectively. The transcatherter internal pudendal arterial chemoembolization were successfully performed in 2 patients with vaginal carcinoma. Conclusion CT is not only a non-invasive method of detecting primary carcinoma of vagina,but also play an important role in differentiating the clinlcal phase and type of it. In more advanced stages of vaginal carcinoma, interventional therapy is chosen as the useful treatment to avoid exenterative surgery, preserve anatomy and function.
