OP24.05: Sonographic follow‐up of solid ovarian lesion < 5 cm in post‐menopausal women: preliminary results

Abstract

endometrial-myometrial junction, presence of the ‘‘bright edge’’ sign at the edges of the lesions, and preservation of normal endometrial lining adjacent to the lesion. Patient clinical history and histological assessment of tumor grading were assessed. Results: 79 cases were analyzed, 26 were benign and 53 cases malignant. Antero-posterior lesion diameter was 8.89 ± 5.58, 14.8 ± 6.99, and 20 ± 10.57 millimeters for the benign, low grade and high grade malignancy lesions respectively, which was statistically significant (P < 0.05). High echogenicity, cystic formation within lesions, presence of ‘‘bright edge’’ and preservation of normal endometrium adjacent to the endometrial lesion were significantly more common in the benign group as compare to malignant lesions (P < 0.05). Complex echogenicity and loss of endometrial-myometrial junction were significantly more common in the malignant lesions group (P < 0.05). These parameters could not distinguish between low and high grade endometrial malignancy. Conclusions: Malignant endometrial lesions are associated with larger antero-posterior diameters. Sonographic parameters such as high echogenicity, cystic formation, presence of ‘‘bright edge’’ and preservation of normal endometrium might be used to distinguish between benign and malignant lesions. These parameters should be assessed, while considering a surgical intervention for endometrial lesions.
