Hematometra as a cause of lumbar radiculopathy. A case report.

Low-back pain combined with a positive straight leg raising test (Lasègue's sign) is uncommon in children and adolescents. Reproductive tract (Mullerian) anomalies causing an accumulation of menstrual blood in the vagina, uterus, and fallopian tubes represent an unusual extraspinal cause of low-back pain. The accumulation of blood in these cavities is termed hematocolpos, hematometra, and hematosalpinx. Amenorrhea with cyclic lower abdominal pain and a presenting pelvic mass are the usual presenting features. In the current report, we describe a case of an adolescent with low-back pain, positive straight leg raising test, and signs of L5 radiculopathy that were attributable to hematometra secondary to congenital partial absence of a vagina. This appears to be the first report of this type of presentation.
