Unusual bleeding in young girls

Vaginal bleeding is uncommon in girls before puberty. 

Sometimes bleeding from the bladder or rectum can be confused with vaginal bleeding.

An ultrasound examination is usually one of the first investigations requested because it is non-invasive. 
We put the ultrasound transducer on the lower abdomen and if the bladder is reasonably full then good images of the bladder, uterus, vagina and ovaries are easily achieved. 

The most common causes of vaginal bleeding in young girls are:

  • Local trauma
  • Presence of a foreign body
  • Ingestion of mother’s oral contraceptive pill
Infections and cancer are extremely rare in this age-group.
