# Hepatic cysts: a survival guide

## TL;DR

This review provides a structured overview of hepatic cysts, categorizing them to aid radiologists in diagnosis and management.

## Contribution

The paper introduces a five-category classification system for hepatic cysts to improve diagnostic clarity and clinical decision-making.

## Key findings

- Hepatic cysts are commonly misclassified as simple or complex without proper distinction.
- A five-category system (congenital, traumatic, neoplastic, inflammatory, and miscellaneous) is proposed for better educational and diagnostic purposes.
- Clinical history and imaging are key to accurate diagnosis and management of hepatic cysts.

## Abstract

Hepatic cysts are quite common in the daily practice of radiologists and are
generally described as simple cysts or as cystic lesions sparsely distributed
throughout the parenchyma, often without the discrimination they merit. Simple
cysts have, by definition, thin walls, one or two thin septa, and homogeneous
fluid content. Such cysts include congenital epithelial cysts, biliary
hamartomas, and peribiliary cysts, as well as those representing Caroli’s
disease or polycystic liver disease. Complex cysts have variable walls, septa,
and contents. They also have various etiologies. A detailed assessment of the
clinical history and imaging characteristics can assist in making the diagnosis
and choosing a course of clinical management. In this review, hepatic cysts are
divided, for educational purposes, into five categories: congenital, traumatic,
neoplastic, inflammatory, and miscellaneous.
