To assess the value of CT and MR in the detection of local tumor recurrence after hysterectomy, we evaluate CT and MRI findings of the vaginal stump in fifteen patiens who unmor recurrence after hysterectomy, for uterine cervical carcinoma (N=14) or endometrial carcinoma (N=1). The presence of stump recurrence was confirmed by needle biogsy in 7 patients and by reoperation in 1 patient. The absence of stump recurrence was diagnosed by needle biopsy in 3 patitients and by clinical follow-up in 4 patients. In 4 patients In eight patients with vaginal stump recurrence, six patients were correctly diagnosed by CT and seven patients by MRI. In remaining seven patients who had no evidence of tumor recurrence, four patients were correctly diagnosed with CT and all the rester patients with MRI. On the bases of our results, MRI seems to be superior to CT in the evaluation of local tumor recuurence after hysterectomy.
