Fitz-Hugh-Curtis syndrome (FHCS) is characterized by perihepatic and pelvic 
inflammation and occurs mostly in women of childbearing age. Here, we report a 
case of FHCS caused by Chlamydia trachomatis in a 50-year-old man. The patient 
presented to our hospital with right upper quadrant abdominal pain, and enhanced 
computed tomography revealed perihepatic and pelvic free fluid and early-phase 
hepatic capsular enhancement. A urine specimen was positive for Chlamydia 
trachomatis. The patient was diagnosed with FHCS due to Chlamydia trachomatis 
infection. In conclusion, FHCS cannot be excluded when men present with right 
upper quadrant abdominal pain without significant signs of biliary tract 
disease.
