Pediatric fitz-hugh-curtis syndrome diagnosed by magnetic resonance imaging.

A 17-year-old girl, who had a sexual intercourse history, presented with fever and right upper quadrant pain. On physical examination, tenderness and percussion tender were identified at that quadrant point, but cervical motion tenderness was not identified. Plane X-ray, abdominal ultrasonography, and nonenhanced abdominal computed tomography, because of contrast agent allergy, showed no specific findings. Nonenhanced magnetic resonance imaging (MRI) demonstrated the high-intensity area in the surface and subcapsule of the liver. From vaginal discharge, polymerase chain reaction for Chlamydia trachomatis was positive. Considered physical and MRI findings, Fitz-Hugh-Curtis syndrome was diagnosed. After Azithromycin administering (1000 mg/day), she got better and discharged.
