[Ovarian torsion revealing an ovarian cavernous hemangioma in a child]

The authors report one case of cavernous hemangioma of the left ovary, which was revealed by ovarian torsion. Such benign tumors of the blood vessels are rare in ovaries during childhood. This hemangioma was observed in a 13-year-old patient, who presented with abdominal and pelvic pain and vomiting. The pelvic mass was noted and sonography revealed a cystic tumor. An annexectomia was realized. Histology showed narcotized ovary cells, with an increased number of vascular channels composed of thin walled vessels, whose wall consisted of an endothelium. This aspect evoked a cavernous hemangioma of the ovary.
