Focal liver lesions found incidentally

Area of Science:

• Hepatology
• Diagnostic Imaging
• Oncology

Background:

• Incidental focal liver lesions are frequently discovered.
• Patients often have a history of liver cirrhosis, colorectal cancer, or present with abdominal pain or trauma.
• Key history elements include risk factors for liver cirrhosis, such as hepatitis, alcohol use, and metabolic syndromes.

Purpose of the Study:

• To outline the diagnostic approach for incidentally found focal liver lesions.
• To emphasize the role of clinical history, laboratory tests, and sequential imaging modalities.
• To guide the selection of appropriate investigations for accurate diagnosis and management.

Main Methods:

• Initial assessment includes patient history, focusing on liver disease risk factors.
• Laboratory tests such as full blood count, liver function tests, and tumor markers are utilized.
• Imaging progresses from B-mode ultrasound to contrast-enhanced ultrasound, CT, and MRI.

Main Results:

• Contrast-enhanced ultrasound offers a feasible, safe, and cost-effective diagnostic option.
• Contrast-enhanced CT is more accurate for diagnosis and surgical planning.
• Contrast-enhanced MRI provides the highest sensitivity, serving as the gold standard.

Conclusions:

• A systematic approach combining clinical, laboratory, and advanced imaging is crucial for diagnosing focal liver lesions.
• Sequential use of imaging modalities, from ultrasound to MRI, enhances diagnostic accuracy.
• Biopsy or surgical excision remains an option when diagnostic uncertainty persists after imaging.
