Ovarian torsion in adolescent with chronic immune thrombocytopenia.

Ovarian torsions in adolescence are rarity, particularly bilateral, with mostly unknown etiology. Enlargement of the ovary contributes to torsion. Young girl presenting with abdominal pains, nausea and vomiting was for two days suspected and observed as gastroenteritis. By exclusion of gastroenteritis she was admitted for gynecological work-up. Ultrasound showed significantly enlarged right ovary, with tumor-like appearance. At the laparotomy, gynecologist found torsioned, necrotic ovary and ovariectomy was performed. Histology showed massive stromal bleeding (haemorrhage). Asymptomatic enlargement of remaining ovary occurred nine months after the ovariectomy. This enlargement was accompanied with platelets’ fall and the possibility of repeated torsion impended. Thrombocytopenia was suspected from the first moment, but diagnosed after the surgery. Thrombocytopenia in adolescence requires additional attention as possible cause of intra-ovarian bleeding with consecutive enlargement and may lead to torsion. Oral contraceptives regulate dysfunctional bleeding, decrease ovarian volume and by so, may minimize risk of torsion. This strategy proved effective in the case we present.
