Clinical value of ultrasonography in the differentia diagnosis of benign and malignant lesions in greater omentum

Objective To evaluate the clinical value of ultrasonography in the differentia diagnosis of benign and malignant lesions in greater omentum.Methods The ultrasonography features of thickened omentum in 62 patients with abdominal distention and ascites of unknown origin were retrospectively analyzed and their pathology results by ultrasound-guided biopsy were contrasted.Results Among 62 patients with thickened omentum,there were 36 cases of tuberculous peritonitis, 5 cases of pseudomyxoma peritonei,18 cases of metastatic adenocarcinoma,2 cases of malignant mesothelioma and 1 case of non-Hodgkin’s lymphoma.Benign lesions mainly appeared as hyperechogenicity,massive thickening and grade 0 of blood flow,while malignant lesions were shown as hypoechogenicity,nodules and grade III of blood flow.The differences were statistically significant(P﹤0.05).Conclusion Ultrasonographic features of benign and malignant lesions in greater omentum are significantly different.Ultrasonography is beneficial to differential them and has significant clinical value.
