目的探讨CT诊断畸胎瘤的准确性。方法选取22例临床考虑为畸胎瘤患者,行CT扫描检查后,跟踪患者术后病理情况,比较CT和患者术后病理诊断的符合率。结果 CT诊断为良性畸胎瘤者14例,恶性畸胎瘤为8例;22例患者术后病理证实为畸胎瘤者20例,其中良性畸胎瘤12例,恶性畸胎瘤8例;CT对畸胎瘤的诊断准确率约为90.9%(20/22),且对畸胎瘤的良、恶性判断较准确。结论 CT对于畸胎瘤具有高诊断率,且对畸胎瘤性质的判断较准确,完全可用于畸胎瘤诊断工作。
Objective To investigate the accuracy of CT diagnosis of teratoma. Methods Twenty-two patients with teratoma were enrolled in this study. The postoperative pathological changes were tracked after CT scan. The coincidence rates of postoperative CT and CT were compared. Results Totally 14 cases of benign teratoma and 8 cases of malignant teratoma were diagnosed by CT. Of the 22 cases, 20 cases were diagnosed as teratoma by pathology, 12 cases were benign teratoma and 8 cases were malignant teratoma. CT diagnostic accuracy of teratoma is about 90.9% (20/22), and teratoma good and bad judgments more accurate. Conclusion CT has a high diagnostic rate for teratoma, and more accurate judgment of the nature of teratoma, can be used for teratoma diagnosis.
