Abstract:
A hepatic abscess is the collection of suppurative matter within the parenchyma of the liver. While most pyogenic liver abscesses (PLAs) are polymicrobial in nature, some rare cases are caused by methicillin-resistant Staphylococcus aureus (MRSA). We present a case of a 43 year-old male without evident exposures who presented with abdominal pain and via CT imaging was found to have monofocal MRSA hepatic abscess. An ultrasonography (US)-guided abscess drainage along with a pigtail catheter placement was performed along with antibiotic initiation. This article emphasizes the clinical manifestations of hepatic abscesses and employs literature reviews to offer a comprehensive approach to managing these patient populations.
Insights
This study details a rare case of a methicillin-resistant Staphylococcus aureus (MRSA) hepatic abscess in a 43-year-old male. Management involved abscess drainage and antibiotics, highlighting clinical presentations and treatment approaches for liver abscesses.
Area of Science:
- Hepatology
- Infectious Diseases
- Radiology
Background:
- Pyogenic liver abscesses (PLAs) are typically polymicrobial infections.
- Methicillin-resistant Staphylococcus aureus (MRSA) is a rare but significant cause of PLAs.
- Prompt diagnosis and management are crucial for patient outcomes.
Observation:
- A 43-year-old male presented with abdominal pain and was diagnosed with a monofocal MRSA hepatic abscess via CT imaging.
- The patient had no apparent risk factors or exposures.
- Ultrasonography-guided drainage with pigtail catheter placement and antibiotic therapy were initiated.
Findings:
- Successful management of a rare monofocal MRSA hepatic abscess was achieved through percutaneous drainage and targeted antibiotics.
- The case underscores the importance of considering MRSA in liver abscess etiology, even without clear exposure history.
- Clinical manifestations of hepatic abscesses can vary, necessitating a thorough diagnostic approach.
Implications:
- This case highlights the need for vigilance in diagnosing and treating MRSA-induced hepatic abscesses.
- Effective management strategies combine interventional procedures like drainage with appropriate antibiotic regimens.
- Further research into MRSA liver abscesses can refine clinical guidelines and improve patient care.
