Discussion On ultrasound the uterus and vagina are distended with fluid showing low level echoes with posterior enhancement. The uterine wall is thicker than the vaginal wall and the vagina appears more distended. Based on patient age and clinical history, and the classic findings of dilated fluid filled vagina and uterus, the diagnosis was hematometrocolpos due to imperforate hymen.
Follow Up The patient was referred to a gynecologist who confirmed the diagnosis.
