title: Primary choriocarcinoma of the uterine cervix: clinical, MRI, and color Doppler ultrasonographic study.
abstract: Primary choriocarcinoma of the uterine cervix was diagnosed in a 38-year-old Japanese woman 4 months after a normal vaginal, term delivery. The patient had experienced irregular genital bleeding for several weeks. A cervical polypoid tumor was detected by visual inspection 4 months after delivery. Magnetic resonance imaging (MRI) and color Doppler ultrasonography revealed a hypervascular tumor (6 cm) in the uterine cervix. The patient's urinary level of human chorionic gonadotropin (hCG) was 128,000 IU/L. Histological examination of a biopsy of the cervical tumor showed choriocarcinoma. After completion of 2 courses of chemotherapy, the patient underwent a total abdominal hysterectomy. Histological examination of uterus showed no evidence of choriocarcinoma. At present, the patient is free of disease. MRI and color Doppler ultrasonography were useful for diagnosis by detecting the abundant blood flow and central necrosis of the cervical tumor.
