大网膜恶性肿瘤的超声诊断价值

Diagnostic value of ultrasonography in greater omentum malignant neoplasm

目的探讨大网膜恶性肿瘤的超声表现特点。方法经手术及穿刺活检证实为大网膜恶性肿瘤的32例患者,其中男性13例,女性19例,年龄29～88岁,平均年龄53.7岁。回顾性分析术前全腹超声检查,并与病理组织检查结果进行对照。结果大网膜呈大片或结节状增厚,呈实性或囊实混合性回声。32例病例中,28例腹腔内常可发现腹腔局限性或大量腹水,占87.50%(28/32)。24例超声发现的大网膜恶性肿瘤中,17例有彩色血流信号,占70.83%。32例大网膜恶性肿瘤中,8例超声检查同时发现网膜外转移,占25.00%。结论超声对大网膜恶性肿瘤具有较高的诊断价值,但超声声像图表现复杂多变,判断性质需结合临床和其他影像学检查。

Objective To study the uhrasonography characteristic of greater omentum malignant neoplasm. Methods Thirty-two patients with greater omentum malignant neoplasm, which was confirmed by operation and biopsy pathology, were enrolled in the current study. Of which, 13 were male and 19 were female, aged 29 - 88 years old（mean age 53.7 years old）. The results of whole abdominal ultrasound examination before operation were analyzed and compared with that of pathological examination. Results Ultrasound examination showed solid or cystic-solid mixed echo, which indicated large-area or nodular thickness of greater omentum. Of the 32 patients, 28 cases had localized or large-area ascites in abdominal cavity（87.50 %）. Of the 24 patients found by ultrasound examination, 17 cases （70.83 %） demonstrated colored flow signal in Doppler ultrasound. Of all the 32 patients in the current study, 8 cases （25.00 % ） combined with metastatic omentum were found by uhrasound examination. Conclusion It demonstrated that uhrasound examination was of considerably high diagnostic value in greater omentum malignant tumors. However, the spectrum of omentum malignant tumors in ultrasongoaphy is very complex, it should be combined with clinical examination and other imaging tests.
