Benign liver lesions refer to non-cancerous abnormalities or growths in the liver.
These lesions can develop for various reasons and are typically identified during imaging tests such as ultrasounds, CT scans, or MRIs performed for other health reasons, as they often do not cause noticeable symptoms.
Understanding the different types of benign liver lesions is essential for appropriate management and treatment.
Some common types include –
These are the most prevalent benign liver lesion. They are composed of a collection of blood vessels and usually do not require treatment unless they are exceptionally large or causing symptoms.
These are fluid-filled sacs that can develop in the liver. Most hepatic cysts do not produce symptoms and do not require treatment unless they become large and cause discomfort or other complications.
Focal Nodular Hyperplasia (FNH)
FNH is a mass of normal liver cells, blood vessels, and connective tissue. It is generally non-cancerous and usually does not require treatment unless it is causing symptoms or there is uncertainty in diagnosis.
These are uncommon, benign liver tumours that primarily affect women of childbearing age who use oral contraceptives. Treatment may be necessary if the adenoma is large or causing symptoms. There are also subtypes that are at greater risk of changing into cancer which can need surgery.
These are cysts caused by a parasitic infection, most commonly from the Echinococcus granulosus tapeworm. In general, these are uncommon. Treatment typically involves surgical removal and antiparasitic medications.
The treatment approach for benign liver lesions varies depending on the type of lesion, its size, and whether it causes any symptoms or complications. Often, benign liver lesions do not require any treatment and may be monitored periodically through imaging tests.
However, some larger lesions or those causing discomfort or concern may require surgical removal or other targeted interventions. If there is sufficient diagnostic doubt, treatment may also be recommended.
Regular follow-up visits with a healthcare provider are essential for individuals with benign liver lesions, particularly for monitoring any changes in the size or characteristics of the lesions. This helps ensure timely detection of any complications or the development of potential issues that may require further evaluation or treatment.
