Nongynecologic causes of unexplained lower abdominal pain in adolescent girls.

Unexplained lower abdominal pain in young women can present a challenge for even the most experienced clinicians. Although the cause is usually benign and self-limited, occasionally a serious underlying disorder exists. Clinicians should have an organized approach for diagnosis and management in an effort to avoid any unnecessary tests or referrals. The most important elements of the evaluation are thorough history, careful physical, and sequential follow-up as needed. Selective use of the laboratory and radiographic studies should be considered on an individual basis. This paper describes four disorders in adolescent girls that may present with pain in the lower abdominal region and closely resemble pathologic conditions within the gynecologic tract. Practitioners who provide services to young women should be aware of these entities so that the correct diagnosis is established as soon as possible and appropriate therapy initiated in a timely fashion.
