Cystic liver lesions: a multimodality imaging review.

Area of Science:

• Radiology
• Hepatology
• Gastroenterology

Background:

• Focal cystic liver lesions are frequently detected in clinical practice.
• These lesions have diverse origins, including congenital, infectious, inflammatory, neoplastic, and miscellaneous causes.
• Distinguishing between these etiologies is vital due to differing clinical implications and management.

Purpose of the Study:

• To emphasize the importance of accurate differentiation of cystic focal liver lesions.
• To guide radiologists in systematically evaluating imaging characteristics for diagnosis.

Main Methods:

• Systematic evaluation of imaging features: location, size, septa, solitary/multiple nature, cyst complexity, and associated findings.
• Correlation of radiologic findings with clinical presentation and laboratory data.

Main Results:

• Imaging appearances of cystic liver lesions often overlap, complicating diagnosis.
• A comprehensive approach combining imaging analysis and clinical correlation is necessary.

Conclusions:

• Accurate differentiation of cystic liver lesions is paramount for appropriate patient management.
• Radiologists should integrate detailed imaging assessment with clinical and laboratory information for definitive diagnosis or differential diagnosis.
