Fitz-Hugh-Curtis syndrome: A cause of right upper quadrant abdominal pain.

Fitz-Hugh-Curtis syndrome (FHCS), also known as perihepatitis, is a rare complication of pelvic inflammatory disease. It has a different incidence depending on which diagnostic criteria are used. FHCS consists of inflammation of the hepatic capsule and surrounding peritoneum, without involvement of the hepatic parenchyma, due to intraperitoneal dissemination from a pelvic infection. Clinical manifestations are nonspecific and include a sudden onset of pain and discomfort in the right hypochondrium, commonly confused with other hepatobiliary, gastrointestinal or renal diseases. In recent years, Multidetector Computed Tomography has proven to be a very useful and non-invasive tool, which offers diagnostic confidence within the appropriate clinical setting. Radiological diagnosis of FHCS can avoid unnecessary surgical procedures.
