A 24-year-old G1P0010 female with a PMHx of ovarian cyst (unknown laterality) and emergency contraceptive use 3 months prior presented with sudden onset abdominal pain (upper > lower) that awoke her from sleep four hours prior to presentation with associated nausea and mild lower back pain. The pain is 10/10, sharp, stabbing, and diffuse. Additionally, she reported trace white vaginal discharge at baseline. No acute increase. She had intermittent vaginal bleeding since contraception use over the past two months, which has now resolved. She denied fever, chills, vomiting, chest pain, shortness of breath, diarrhea, or constipation. No pertinent surgical history.
Constitutional: Uncomfortable. Appearing to be in acute pain.
Cardiovascular: Tachycardia. Regular rhythm and normal heart sounds.
Pulmonary: No respiratory distress. Breath sounds normal.
Abdominal: Diffusely tender abdomen with voluntary guarding, otherwise soft. Normoactive bowel sounds. Negative Murphy’s sign.
Pelvic: Scant white vaginal discharge and CMT. No vaginal bleeding, lacerations, or external lesions.
Neurologic: A&O x 3
WBC: 18.9 k/uL
Hgb: 10.5 g/dL
BMP, lipase, Alk phos/Bili/ALT/AST, PT/PTT, and lactate: Unremarkable
Serum HCG: Negative
Urinalysis (UA): Unremarkable
COVID: Negative
An ideal RUQ ultrasound visualizes the liver, Morrison’s pouch, superior and inferior poles of the right kidney, and diaphragm in the coronal plane. Here, we see a thickened hepatic capsule, septations, and trace ascites.
Fitz-Hugh-Curtis syndrome (FHCS) is characterized by perihepatitis in the setting of pelvic inflammatory disease (PID). It traditionally presents with right upper abdominal pain with associated nausea, vomiting, and fever in women of childbearing age. While overall considered a rare manifestation of PID, the true incidence of FHCS is poorly defined in the literature [1]. The pathophysiology of spread is also poorly understood. It is speculated that bacteria (N. gonorrhoeae, C. trachomatis) travel to the liver via blood, lymphatics or peritoneal fluid, causing perihepatitis [1]. Diagnosing FHCS poses a diagnostic challenge to clinicians. Traditionally, the diagnosis is made via laparoscopic exploration of the abdomen with visualization of the characteristic “violin-string” adhesions, with growing evidence also supporting the use of contrast-enhanced CT [1]. Limited evidence exists to support the use of ultrasonography in diagnosing FHCS. One case report published in 1993 used RUQ abdominal ultrasound to identify septations (violin-string adhesions) and ascites to ultimately diagnose FHCS, later confirmed by serologic and operative evidence [2]. Another case report from 2018 used ultrasonography to identify a thickened hepatic capsule in an 18-year-old female with RUQ pain, later confirming FHCS by CT without the need for laparotomy [3]. While more research is needed, identification of FHCS via bedside ultrasonography in the emergency setting followed by appropriate antibiotic therapy can be an effective approach to FHCS, ideally reserving laparoscopy only for lysis of adhesions in refractory cases.
