Abstract:
Purpose To summarize the CT features and clinical characteristics of atypical primary fallopian tube cancer (PCFT) and ovarian cystadenocarcinoma (OCA), in order to improved the diagnosis. Materials and Methods CT findings and clinical data of 12 patients with atypical PCFT (PCFT group) and 20 patients with OCA (OCA group) were retrospectively studied. All patients were confirmed by pathology. Serum CA125 level, clinical characteristics and CT features of two groups were compared. Results Serum CA125 level of PCFT group and OCA group were (486.13±23.89) U/ml and (1606.94±62.86) U/ml, respectively. There was statistic difference between the two groups (P<0.01). There was significant differences on vaginal bleeding and vaginal discharge between the two groups (P<0.01). There were 4 cases with solid mass, 8 cases with cystic solid mass in PCFT group. And in OCA group, 16 cases with cystic solid mass and 4 cases with cystic mass were revealed, which showed statistic differences between the two groups (P<0.05). Some other findings also showed statistic differences including the diameter of ovarian vein on the affected side, the diameter of the round ligament of uterus on the affected side, tumor volume, and CT values of the mass in venous phase and delay phase (P<0.05 or P<0.01). However, there were no statistic significance in the size of metastatic lymph nodes, the mean CT value of the mass on plain scan and in the arterial phase (P>0.05). Conclusion Clinical findings of serum CA125 level, vaginal bleeding, and vaginal discharge combine with imaging findings of diameter of the ovarian vein in the affected side, diameter of ipsilateral round ligament of uterus, tumor volume, CT values of the mass in venous and delay phase would be the key points for differential diagnosis of PCFT and OCA.
