LIVER ABSCESS ON CECT
๐ฆ CT Imaging of Liver Abscess – Key Signs Every Radiographer Should Know
๐ Introduction
Liver abscess is a potentially life-threatening condition that requires prompt diagnosis and treatment. Radiological imaging, especially contrast-enhanced CT (CECT), plays a critical role in early detection and management. This article will walk you through the key CT features of liver abscess, its types, and what radiographers should look out for.
๐งซ What is a Liver Abscess?
A liver abscess is a localized collection of pus within the liver parenchyma caused by infection. It can be:
- Pyogenic (bacterial origin)
- Amoebic (caused by Entamoeba histolytica)
- Fungal (less common, usually in immunocompromised patients)
๐ผ️ CT Imaging Findings
Here's a contrast-enhanced axial CT image showing a typical liver abscess (indicated by the red arrow):

Key features on CT:
- Hypodense lesion (low attenuation)
- Thick or irregular walls
- Central necrosis or fluid density
- Peripheral rim enhancement (on post-contrast phase)
- May cause mass effect on adjacent structures
- Sometimes associated with gas formation (in pyogenic abscess)
๐ฉบ Clinical Presentation
Patients usually present with:
- High-grade fever
- Right upper quadrant abdominal pain
- Malaise or fatigue
- Hepatomegaly (sometimes)
Lab Findings:
- Elevated WBC count
- Elevated alkaline phosphatase (ALP)
- Mildly increased bilirubin (sometimes)
๐ Role of Radiographer (Most important)
As a radiographer, your role includes:
- Ensuring proper contrast phases (arterial, venous, delayed if needed)
- Identifying key signs like rim enhancement, gas bubbles
- Assisting in CT-guided aspiration or drainage
- Educating and reassuring patients during imaging
๐งช Treatment Overview
- Broad-spectrum antibiotics
- CT-guided/USG-guided aspiration or percutaneous catheter drainage
- Surgery (only in severe or non-responsive cases)
๐ฏ Conclusion
Liver abscess is a radiologically visible and treatable pathology. Timely identification on CT scans can significantly reduce complications. As a radiographer or radiology student, learning to recognize these classic imaging patterns is crucial for patient care...
