卵巢卵泡膜细胞瘤的超声表现分析

Ultrasonography of Ovarian Thecoma

目的 :探讨卵巢卵泡膜细胞瘤的声像图表现 ,及与相应的病理改变和临床症状的关系 ,以提高术前诊断准确率。材料和方法 :2 6例患者术前行彩超检查 ,术后将手术及病理所见与超声表现进行对照分析。结果 :2 6个肿瘤中 2 3个呈实性、1个呈囊实性、1个呈囊性、1个含有机化的凝血块。实性肿瘤中有 19个呈低回声 ,其中 8个后方伴有声衰减。CVI仅于 1例肿瘤内探及少许血流信号 ,余均未见血流。 1例实性肿瘤被超声误判为囊肿。结论 :大多数卵巢卵泡膜细胞瘤的声像图表现是呈低回声实性包块 ,边界清晰 ,可伴有后方声衰减 ,内无或仅有少许血流信号 ;这些超声表现对提示卵巢卵泡膜细胞瘤的诊断有重要价值。

Purpose:To explore the relationship of ultrasonography of ovarian thecoma with correspondent pathology and clinic data. Materials and Methods:26 cases of ovarian thecoma were examined preoperatively using Color Doppler ultrasound and followed up postoperatively. The ultrasonographic features was compared with surgical and pathologic findings. Results:There were 23 solid tumors, 1 semi cystic, 1 cystic and 1 cyst with organized blood found in those patients. Among the 23 solid tumors 19 were hypoechoic and 8 had posterior acoustic attenuation. CVI showed little blood signal in 1 and no blood signal in the other cases. Conclusion:By ultrasonogaphy ,most ovarian theca tumor appear as hypoechoic solid tumor with clear boundary, possibly posterior acoustic attenuation and no or little blood signal.
