A 22-year-old nulligravida was evaluated at a hospital for persistent vaginal bleeding and malodorous discharge. She was considered to have a foreign body in her vagina, apparently penetrating the uterine cervix with perforation into the peritoneal cavity. By history the object had been present for 6 years. She was transferred to our university hospital for surgical removal. On computed tomography and magnetic resonance imaging, the object was cylindrical and was located in the vaginal vault without evidence of perforation. With both modalities it appeared lucent relative to surrounding tissues. Removal required limited dissection of the vaginal wall, and the object proved to be a plastic container cap. No vesico-vaginal fistula or other complication was present. Precise early diagnosis was difficult in this case, but details of the chief complaint offered valuable clues and imaging was informative.
