# Positive Murphy's Sign of Fitz-Hugh-Curtis Syndrome

## TL;DR

A woman with right upper quadrant pain was diagnosed with Fitz-Hugh-Curtis syndrome after initial misdiagnosis, highlighting the importance of considering this condition in similar cases.

## Contribution

This case emphasizes the need for thorough evaluation and history-taking to diagnose Fitz-Hugh-Curtis syndrome in patients with atypical presentations.

## Key findings

- Right upper quadrant pain with a positive Murphy's sign can be caused by Fitz-Hugh-Curtis syndrome, not biliary disease.
- A detailed patient history, including pelvic inflammatory disease symptoms, is crucial for accurate diagnosis.
- Treatment with ceftriaxone and minocycline resolved the patient's symptoms within seven days.

## Abstract

A Japanese woman in her 30s presented to the emergency department at midnight with right upper quadrant pain that had lasted for a week. Without a definitive diagnosis, she was prescribed acetaminophen and levofloxacin and discharged. When her pain persisted the next morning, she visited her primary care physician and reported fever and right upper quadrant pain. She was referred back to the emergency department with suspected cholecystitis.

The patient's vital signs were stable, including a temperature of 36.6°C. Physical examination revealed right upper abdominal tenderness and a positive Murphy's sign, but no other abdominal tenderness. Laboratory tests showed normal white blood cell count and liver enzymes and a slightly elevated C-reactive protein concentration (2.44 mg/dL). Abdominal ultrasound showed no abnormalities. Further questioning revealed a history of unprotected sex, lower abdominal pain before the right upper quadrant pain, and increased vaginal discharge. Urine polymerase chain reaction confirmed Chlamydia trachomatis. The patient was diagnosed with pelvic inflammatory disease, specifically Fitz-Hugh-Curtis syndrome (FHCS), and treated with ceftriaxone and minocycline. Her symptoms improved after seven days of treatment.

This case highlights the need for careful clinical evaluation and consideration of FHCS in patients presenting with right upper quadrant pain, especially when laboratory findings and imaging studies do not support biliary disease. A thorough history including symptoms of pelvic inflammatory disease, such as lower abdominal pain and vaginal discharge, is also necessary to accurately diagnose FHCS.
