Usually, liver hemangiomas are discovered incidentally during routine physical examination and ultrasound. So what are the characteristics of liver hemangioma on ultrasound?
1. Overview of liver hemangioma
Liver hemangioma is a benign tumor. Hemangiomas can form anywhere in the body, however, the liver is the most common site where hemangiomas appear. Liver hemangioma is a tumor with many blood vessels. This is a rare disease and occurs more often in women than in men.

Many studies suggest that female sex hormones can contribute to hemangiomas in the liver in women.
In the liver, hemangiomas usually appear in the right liver and located in the subcapsular region, with a size of a few mm to 3-4 cm. Patients are usually found to have a single tumor of small size, but there are also cases of patients with multiple hemangiomas or large tumors.

CT scan: CT scan is a computerized tomography technique that uses X-rays to record, process, and build images of liver slices. MRI scan: An MRI scan, also known as magnetic resonance imaging, is an imaging technique that uses radio waves and a magnetic field to recreate images of the liver. Radiographs: Liver hemangiomas can also be diagnosed by radiography. This is a technique to reconstruct the liver image using radioactive isotopes.

3. Liver hemangioma on ultrasound
Among the diagnostic methods for liver hemangiomas mentioned above, liver ultrasound helps to detect and classify hemangiomas as typical or atypical.Typical liver hemangioma: This is a common form, with the average tumor size being less than 3cm. The image of liver hemangioma on ultrasound is a homonymous and hyperechoic mass, clearly demarcated, and the posterior region is hyperechoic. In the central region of the lesion may be hypoechoic or thin. Atypical hepatic hemangiomas: On ultrasound, atypical liver hemangiomas may be hypoechoic, homophonic or non-echoic. Hypoechoic occurs in the case of fatty liver, hematopoietic tumors can reduce the sound compared to the adjacent parenchyma. Non-homonymous occurs in the case of cirrhosis, liver thrombosis, tumor bleeding, or liquefied tumor, pseudocyst, at this time the image of liver hemangioma on ultrasound is a large mass, non-homonymous, regional hyperechoic periphery, hypoechoic or central hollow. Homophones are rare.

4. What to do when detecting liver hemangiomas on ultrasound?
Patients should not be too worried when detecting liver hemangiomas on ultrasound, because this is a benign tumor and can be treated. As mentioned above, most cases of hemangiomas in the liver are small in size and do not require treatment.Currently, there are no drugs that can reduce or completely eliminate the tumor. For rare cases of large hemangiomas, in order to prevent the tumor from bursting and bleeding or causing pain, the patient is now treated with one of the methods such as surgical removal of part of the liver hemangioma. or radiotherapy to embolize the artery feeding the tumor, ...
The liver hemangioma on ultrasound can be a very large hypoechoic or non-homogenous mass, depending on the typical or atypical form. Most cases of liver hemangiomas are small in size and do not require treatment. Only treat in case the tumor is large and painful, preventing tumor rupture and life-threatening visceral bleeding.
Although, liver hemangioma is a benign tumor, but when there is a history of liver diseases, the patient should have regular health check-ups to promptly detect the disease, providing a high chance of treatment.
