Ovarian hemangioma is a rare ovarian tumor. The imaging manifestations were rarely mentioned in previous literatures. One of the patients came to hospital with the complaints of an elevation of CA125. Another two patients found a mass in adnexa area accidentally. The oophorectomy procedures were performed and the pathological results of ovarian hemangioma were concluded. We summarized the ultrasound features of three cases retrospectively, of which could provide more information before operation to guide a management direction. A well-defined, regular-shape solid mass in ovary could be considered the possibility of hemangioma, especially when a richly vascularized tumor with prominent blood flow is detected on color Doppler sonography.
