Fitz-Hugh-Curtis syndrome resulting in nutmeg liver on computed tomography

A case of Fitz-Hugh-Curtis syndrome diagnosed by noninvasive metagenomic next-generation sequencing

OBJECTIVE

Fitz-Hugh-Curtis Syndrome (FHCS) is an inflammation of the liver capsule as a complication of pelvic inflammatory disease (PID) in sexually active women, mostly associated with Chlamydia trachomatis (C. trachomatis) and Neisseria gonorrhoeae. Classically presenting as sharp right upper quadrant pain, usually accompanied salpingitis and ascites. With nonspecific clinical presentation and poor specificity, definitive diagnosis needs tissue biopsy and culture by laparoscopy.

CASE REPORT

We report the case of a 22-year-old female with a 2-month history of abdominal pain and distention. Symptomatic relief when supportive treatments were given, with the ultrasound and PET-CT suggested advanced bilateral ovarian cancer. After metagenomic next-generation sequencing (mNGS) detected C. trachomatis in ascitic fluid. Following anti-infective medication, clinical improvement was satisfactory and the patient was discharged.

CONCLUSION

FHCS with distention was rare and challenging to diagnose. The mNGS would be a potent, non-invasive pathogen detection method with significant sensitivity and specificity.

Hepatic perfusional changes on CT and MRI: a radiology primer

Hepatic perfusional changes are common in response to, or as a result of, a multitude of pathological processes. These can be neoplastic, inflammatory, fibrotic, or ischemic in origin, to name a few. The liver, having a dual blood supply, is a unique organ to study using contrast-enhanced CT and MRI imaging due to its varied appearance on multiphasic imaging. Knowledge of the CT and MRI appearance of hepatic perfusional changes, in addition to the clinical presentation, can often result in an accurate differential diagnosis. Many of the conditions that cause these changes in hepatic blood flow result in similar appearances on imaging. As a result, it is important that radiologists be aware of common pitfalls when dealing with hepatic perfusional changes to prevent misdiagnosis or delayed diagnosis. As such, this review will focus on some of the various causes of hepatic perfusional changes and how to accurately identify and diagnose them based on their CT and MRI appearance.

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.
