Imaging of Haematocolpos

Haematocolpos is the progressive accumulation of menstrual blood in the vaginal cavity. It is often the result of imperforation of the hymen. The clinical symptoms are cyclical pelvic pain and primary amenorrhoea. More rarely, it may be revealed by a pelvic mass [1, 2]. We report a case of haematocolpos secondary to hymenal imperforation diagnosed in a young girl presenting with primary amenorrhoea and a pelvic mass. Ultrasound and magnetic resonance imaging (MRI) remain the reference examinations to confirm haematocolpos and to exclude other associated genitourinary malformations [2].
