Introduction

In general, ultrasound examination has high accuracy in diagnosing hepatic hemangiomas and is the preferred initial screening method in clinical practice. It can identify most typical cases of hepatic hemangioma, but may carry a risk of misdiagnosis for small or atypical lesions, necessitating additional tests for definitive diagnosis. To minimize the risk of misdiagnosis, it is recommended that ultrasound examinations be performed under the guidance of a qualified physician, and patients should follow medical instructions to prepare properly before the examination.

Under normal circumstances, ultrasound examination has a high accuracy rate for diagnosing hepatic hemangiomas and is the preferred initial screening method in clinical practice. It can identify most typical hepatic hemangiomas; however, there remains a risk of misdiagnosis for small or atypical hemangiomas, which may require additional tests for definitive diagnosis. Detailed analysis is as follows:

Ultrasound is non-invasive, convenient, and cost-effective, with a diagnostic concordance rate of 80%–90% for typical hepatic hemangiomas. On ultrasound, typical hemangiomas appear as round or oval nodules with well-defined boundaries, showing either hypoechoic or hyperechoic patterns, and some may display a mesh-like structure. When combined with clinical information such as absence of hepatitis or cirrhosis history and normal tumor markers, a preliminary diagnosis can be made. Additionally, ultrasound allows dynamic monitoring of hemangioma size changes, making it suitable for long-term follow-up.

However, due to limited resolution, ultrasound may fail to accurately detect small hemangiomas less than 1 cm in diameter, potentially leading to confusion with intrahepatic bile duct stones or small hepatocellular carcinomas. Atypical hemangiomas may also be misdiagnosed. In such cases, further evaluation using contrast-enhanced CT or magnetic resonance imaging (MRI) is recommended to confirm the diagnosis based on the characteristic "early enhancement and late washout" pattern of hemangiomas.

To minimize the risk of misdiagnosis, it is recommended that ultrasound examinations be performed under the guidance of a qualified physician. Patients should follow medical instructions when preparing for the exam and avoid strenuous exercise or dietary irritants to improve diagnostic reliability.

What are the classifications of hepatic hemangiomas in adults?

In general, adult hepatic hemangiomas are primarily classified according to pathology and morphology into cavernous hemangiomas, sclerosing hemangiomas, epithelioid hemangiomas, capillary hemangiomas, and intravascular endothelial cell tumors. Clinically, physicians develop management strategies based on the type, size, location of the hemangioma, and the patient's symptoms. Most small, asymptomatic lesions require only periodic ultrasound follow-up.

Are liver hemangiomas hereditary?

In general, hepatic hemangiomas are not hereditary diseases and are usually not passed on genetically. Regular monitoring of the size and morphology of the hemangioma via ultrasound is recommended, with annual follow-up examinations. It is advisable to avoid alcohol consumption and staying up late to reduce the metabolic burden on the liver and prevent stimulating hemangioma growth. Additionally, medications that may affect hormone levels should be avoided.

What does it mean to have nodules on the liver, and what should be done?

In general, the main causes of liver nodules include intrahepatic bile duct stones, hepatic hemangioma, viral hepatitis, alcoholic liver disease, and hepatocellular adenoma. Depending on the specific condition, treatments such as conservative management, medication, or surgical intervention may be selected to improve outcomes. In daily life, it is important to control alcohol intake and avoid excessive drinking, maintain a balanced diet, and reduce consumption of high-fat and high-sugar foods.

How is a hemangioma on the liver treated?

In general, hepatic hemangiomas may be caused by genetic factors, hormonal fluctuations, abnormal proliferation of vascular endothelial cells, intrahepatic vascular malformations, abnormal repair following liver injury, and other factors. It is recommended to seek timely medical attention, determine the size and location of the hemangioma, and then follow the doctor's guidance for improvement through regular monitoring, medication, surgical treatment, or other appropriate methods.
