A patient presents with recent PID and right upper quadrant pain. What condition should be considered?

In the context of a patient presenting with recent pelvic inflammatory disease (PID) accompanied by right upper quadrant (RUQ) pain, it is important to consider Fitz-Hugh-Curtis syndrome. This condition is characterized by the development of perihepatitis, which is inflammation of the liver capsule, often as a complication of PID, particularly with infections caused by Neisseria gonorrhoeae or Chlamydia trachomatis.

Patients may experience RUQ pain due to the inflammatory changes around the liver, which can mimic the symptoms of gallbladder disease or other abdominal pathologies. The association between PID and RUQ pain is a key point, as Fitz-Hugh-Curtis syndrome is specifically known to occur following an ascending infection from the reproductive tract to the peritoneal cavity and the liver.

Other conditions, while they may present with RUQ pain, do not have this direct connection to recent PID. Cholecystitis, for example, could present with similar pain but isn't specifically linked to PID. Liver abscesses may cause RUQ pain as well but typically would not be a direct consequence of recent PID in the same way that Fitz-Hugh-Curtis syndrome would. Similarly, appendicitis is primarily
