This study evaluated sonographic characteristics of benign ovarian masses in premenopausal women, finding that follow-up ultrasound helps distinguish resolving hemorrhagic cysts from persistent lesions like endometriomas to avoid unnecessary surgery.

This prospective study evaluated the sonographic characteristics of 56 benign, non-pregnancy-related ovarian masses in premenopausal women to determine which lesions resolve spontaneously. Researchers conducted follow-up ultrasounds over at least one menstrual cycle and categorized initial imaging patterns into five distinct types ranging from simple anechoic cysts to complex solid masses. The findings revealed that 55 percent of these masses resolved without intervention, with hemorrhagic cysts accounting for the majority of spontaneous resolutions, while unresolved cases included endometriomas and various adenomas. This paper is centrally about endometriosis — specifically, it identifies endometrioma as a key differential diagnosis among ovarian masses that fail to resolve spontaneously, highlighting the diagnostic challenge of distinguishing them from hemorrhagic functional cysts via ultrasonography.

Abstract

To evaluate the sonographic characteristics of functional ovarian cyst with or without hemorrhage, we peformeda prospective analysis of 56 cases of benign, cystic ovarian mass that is not related to pregnancy inpremenopausal women. At least two examinations with transabdominal and/or transvaginal US were performed in allpatients over one menstrual cycle time interval . US patterns of the masses were cathgorized into 5 types : type A; anechoic, unilocular cyst, type B ; unilocular cyst with internal echoes. type C ; septated cyst, type D ;complex cyst, type E ; solid mass with posterior reenhancement. Fifty five percent (31 cases) of the massesresolved spontaneously on follow-up US examination. In these cases with spontaneous resolution, 11 cases (35.5%)were simple cyst, while the remaining 20 cases (64.5%) were hemorrhagic ovarian cysts having variable sonographicfindings of types B to E. Eleven cases with no resolution were proven surgically as endometrioma (n=4),hemorrhagic parovarian cyst (n=2), serous cystadenoma (n=2), mucinous cystadenoma (n=2), and tuboovarian abscess(n=1). Sonographic differentiation of these cases from hemorrhagic cysts was difficult. in conclusion, as thefunctional ovarian cysts, especially the hemorrhagic cysts, are common and show variable sonographic features, werecommend a follow-up US examination after on or two mentrual cycles in all premenopausal women with benign,cystic ovarian mass to eliminate unnecessary operation.\nKeyword : Ovary,neoplasms
