摘　　要：目的:总结分析畸胎类肿瘤影像学检查的诊断价值。材料与方法:对90例经手术病理证实的畸胎类肿瘤的X线、超声、CT及MRI检查的表现特点进行分析。结果:超声诊断59例,CT诊断29例,MRI诊断10例,常规X线诊断2例。其中良性囊性畸胎瘤39例,囊实性畸胎瘤51例。结论:常规X线诊断价值较小,对于胸部纵隔内畸胎瘤有一定诊断价值,超声、CT及MRI对畸胎瘤的诊断均具有重要价值,超声检查方便、价廉,可改变体位实时成像,特别对腹部盆腔畸胎瘤具有优势。CT对钙化与骨骼的显示优于超声、MRI,而MRI多轴位成像能更好显示肿瘤全貌、囊内容物的成分。Objective The value of imaging diagnosis of teratoma were summarized and analysed. Materials and Methods The imaging features including X-ray ultrasound CT and MRI of 90 cases of teratoma confirmed by pathology after surgery were analyzed. Result Ultrasound diagnosed 59 cases CT 29 cases MRI 10 cases X-ray 2 cases. Thirty nine cases were benign cystic teratoma and 51 cases cystic solid teratoma. Conclusion The diagnostic value of X-ray is small but has some diagnostic value when teratomas lie in thoracic mediastinum. Ultrasound CT MRI have important value in diagnosing terato dermoid tumors and ultrasound is convenient and cheap especially superior in diagnosing pelvic teratoma. CT superior to ultrasound and MRI in display calcifications and bones. MRI may display tumor's whole picture and components.
