A pelvic CT examination displayed a 6.5 cm×3.0 cm shadow of a soft-tissue tumor growing longitudinally in her supravaginal uterine area （Fig. 1）. The density of the shadow was uneven, in which there were irregular low-density loci, an indication of a compression of the colon and bladder and a diffuse boundary between the posterior wall of the urinary bladder and tumor. No abnormalities were found in either kidney or ovary, the liver or gall bladder. Also no obvious lesions were seen on the chest X-ray film, and routine blood and urine laboratory examinations were normal.展开更多
