Benign hepatic neoplasms: an update on cross-sectional imaging spectrum

Area of Science:

• Hepatology
• Oncology
• Radiology

Background:

• Benign hepatic neoplasms are a diverse group of tumors originating in the liver.
• Classification systems, such as the 2000 World Health Organization system, categorize these neoplasms based on cell of origin (epithelial, nonepithelial, miscellaneous).
• These tumors exhibit a wide range of histomorphologic features and variable tumor biology.

Purpose of the Study:

• To review the classification of benign hepatic neoplasms.
• To correlate histomorphologic changes with imaging findings.
• To highlight neoplasms with pathognomic imaging features for accurate characterization and management.

Main Methods:

• Review of current literature on benign hepatic neoplasms.
• Analysis of histomorphologic characteristics and classification systems.
• Correlation of imaging findings with histopathology.

Main Results:

• Benign hepatic neoplasms are classified into epithelial, nonepithelial, and miscellaneous categories.
• Imaging findings vary widely, reflecting underlying histomorphologic changes.
• Certain neoplasms present with characteristic imaging features allowing for definitive diagnosis.

Conclusions:

• Accurate classification of benign hepatic neoplasms is essential.
• Imaging plays a critical role in the characterization of these liver tumors.
• Recognition of pathognomic imaging findings facilitates optimal patient management.
