Fitz-Hugh-Curtis syndrome: a diagnosis to consider in women with right upper quadrant pain.

Fitz-Hugh-Curtis syndrome--inflammation of the liver capsule associated with genital tract infection--occurs in up to one fourth of patients with pelvic inflammatory disease (PID). Classically presenting as sharp, pleuritic right upper quadrant pain, usually but not always accompanied by signs of salpingitis, it can mimic many other common disorders such as cholecystitis and pyelonephritis.
