ITZ-HUGH-CURTIS SYNDROME-perihepatitis associated with pelvic inflammatory disease-can pose a diagnostic challenge to the clinician, especially when right upper quadrant pain predominates, mimicking acute gall bladder disease. This article reviews the etiology, pathogenesis, diagnosis, and treatment of this syndrome. s HISTORICAL PERSPECTIVE Association with gonorrhea Fitz-Hugh-Curtis syndrome was first described in 1920 by Carlos Stajano, 1 who noted adhesions between the liver capsule and anterior abdominal wall in patients with gonococcal infection and right upper quadrant pain. In the 1930s Thomas Fitz-Hugh and Arthur Curtis also described the syndrome and made the connection between the acute clinical syndrome of right upper quadrant pain following a pelvic infection and the "violinstring" adhesions found in women with evidence of prior salpingitis. 2,3 Curtis described several cases of these very typical adhesions between the liver and the abdominal wall in patients with gonococcal disease and noted that similar adhesions were not found in other causes of peritonitis, suggesting the combination was a unique syndrome. 4 Fitz-Hugh suggested that Neisseria gonorrhoeae was the cause when he found gram-negative diplococci on smears from the liver capsule in patients with the syndrome. 2 Since then, the diagnosis of Fitz-Hugh-Curtis syndrome has largely been a clinical
