Non-infectious Hepatic Cystic Lesions: A Narrative Review

Area of Science:

• Hepatology
• Radiology
• Gastroenterology

Background:

• Hepatic cysts are common, with varied causes and severity.
• Benign cysts are most frequent, but malignant lesions can mimic them.
• Non-parasitic cysts include simple biliary cysts, hamartomas, and neoplasms.

Purpose of the Study:

• To review non-parasitic hepatic cystic lesions.
• To detail their pathophysiology, epidemiology, and malignant potential.
• To discuss diagnostic imaging and treatment strategies.

Main Methods:

• Review of literature on non-parasitic hepatic cysts.
• Analysis of clinical and imaging features.
• Discussion of diagnostic modalities and treatment options.

Main Results:

• Simple biliary cysts are common and diagnosed with ultrasound.
• Complex lesions require advanced imaging (CT, MRI).
• Differential diagnosis is key to distinguishing benign from malignant conditions.

Conclusions:

• Accurate diagnosis of hepatic cysts is crucial for patient management.
• Imaging plays a key role in differentiating cyst types.
• Treatment ranges from conservative to surgical interventions based on cyst characteristics.
