Fitz-Hugh-Curtis syndrome in adolescent and young adult females: Utility of a decision rule.

Background: The diagnosis of Fitz-Hugh-Curtis syndrome (FHC) is often missed or delayed in patients with right upper quadrant pain (RUQ).

Objective: To develop a decision rule that predicts FHC in females with RUQ pain based on a constellation of historical features, physical examination findings and laboratory results.

Methods: We conducted a prospective study to test the utility of our FHC decision rule in sexually active females, aged 13-20 years, with RUQ pain who were seen in an urban ED over 57 months.
