[Imperforate hymen as a cause of abdominal pain in adolescents: a case report].

The imperforate hymen is a congenital anomaly of the female genital development. This is a rare pathology with an estimated incidence of 0.1% in female newborns. In many cases, the diagnosis goes unnoticed until puberty, debuting with cyclical abdominal pain in adolescents who have not submitted menarche. Diagnosis is based on history and physical examination, although additional tests, especially the ultrasound that allows to confirm clinical diagnosis and to exclude other genital malformations. We report a case of a 13-year-old that was diagnosed after consulting several times for recurrent abdominal pain.
