- To review the pathogenesis and imaging spectrum of hepatic cystic lesions. - To provide a practical diagnostic algorithm that facilitates differential diagnosis.
Hepatic cystic lesions – defined as lesions with predominant near-water content – are commonly encountered in everyday practice.
The differential diagnosis ranges from benign developmental to malignant lesions,
whose prognosis and management is radically different. An important first step for narrowing the differential diagnosis is to determine the presence or absence of complex features in cystic liver lesions. Simple hepatic cystic lesions Simple cysts are one of the commonest liver lesions...
Findings and procedure details
Simple hepatic cystic lesions appear as round or ovoid fluid-containing lesions with smooth imperceptible well-defined walls and no evidence of complex internal features,
such as septations,
nodularity or wall calcification.
No enhancement is seen after intravenous contrast media administration (Fig3). Imaging features On ultrasound,
a hepatic cyst appears as a well-circumscribed anechoic lesion with posterior acoustic enhancement. On CT: homogeneous hypoattenuation (water...
A practical diagnostic algorithm based on key imaging features and patient history may guide the radiologist in making the diagnosis or a reasonable differential diagnosis of hepatic cystic lesions.
