OBJECTIVE: The purpose of this study was to quantify the likelihood ratio (LR) of specific sonographic features and experienced sonologist assessment in diagnosing a hemorrhagic ovarian cyst and to better understand the diagnostic power of sonography in making this diagnosis. METHODS: Two sonologists, blinded to the patient's clinical history, independently reviewed the sonograms of 252 adnexal masses. For each mass, each sonologist recorded features using a standardized checklist, which included observations regarding the presence of fibrin strands, a retracting clot, septations, and wall irregularity. Each reviewer independently chose 1 specific conclusion from a list of possibilities that included the diagnosis of a hemorrhagic ovarian cyst. Sonographic observations and sonologist predictions were compared with pathologic findings (n = 214) or follow-up sonography (n = 38). RESULTS: Of the 252 masses, there were 30 hemorrhagic cysts. One sonologist correctly identified 25 hemorrhagic cysts, with 1 false-positive, 2 false-negative, and 3 indeterminate calls (LR 185). The other sonologist correctly identified 24 hemorrhagic cysts, with 1 false-positive, 0 false-negative, and 6 indeterminate calls (LR 178). The 2 cases incorrectly diagnosed as hemorrhagic cysts were endometriomas at pathologic diagnosis. Specific sonographic observations and combinations of observations performed as follows: retracting clot (LR >67); fibrin strands (LR 40); fibrin strands and no septations (LR 100); and fibrin strands, no septations, and smooth wall (LR 200). CONCLUSIONS: Fibrin strands and a retracting clot are paramount observations in allowing high confidence in the diagnosis of hemorrhagic ovarian cysts. Approximately 90% of hemorrhagic ovarian cysts will exhibit at least 1 of these 2 features.
