Is hemangioma in liver serious?
The hemangioma, or tumor, is a tangle of blood vessels. It’s the most common noncancerous growth in the liver. It’s rarely serious and doesn’t turn into liver cancer even when you don’t treat it.

An atypical hemangioma is a hemangioma that does not present with a classical imaging appearance and may resemble a more aggressive type of lesion [14]. Different dis- tributions of tissue content within these lesions results in this idiosyncrasy.
What size liver hemangioma needs surgery?
The main indication for surgery is giant (> 10 cm) liver hemangioma, with or without symptoms. Laparoscopic hepatectomy was an effective option for hepatic hemangioma treatment. For extremely giant hemangiomas, 3D image reconstruction was indispensable. Hepatectomy should be performed by experienced hepatic surgeons.
What is an atypical hemangioma of liver?
Atypical hemangioma is a variant of hepatic hemangioma with atypical imaging finding features on CT and MRI that can be confused with hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and mixed hepatocellular cholangiocarcinoma (HCC-CC).

Atypical vertebral hemangioma: an aggressive form of a benign disease.

How is liver hemangioma treated?
Treatment
- Surgery to remove the liver hemangioma. If the hemangioma can be easily separated from the liver, your doctor may recommend surgery to remove the mass.
- Surgery to remove part of the liver, including the hemangioma.
- Procedures to stop blood flow to the hemangioma.
- Liver transplant surgery.
- Radiation therapy.
How do you stop a liver hemangioma from growing?
Without a blood supply, the hemangioma may stop growing or shrink. Two ways to stop the blood flow are tying off the main artery (hepatic artery ligation) or injecting medication into the artery to block it (arterial embolization).
Do liver hemangiomas need treatment?
If your liver hemangioma is small and doesn’t cause any signs or symptoms, you won’t need treatment. In most cases a liver hemangioma will never grow and will never cause problems. Your doctor may schedule follow-up exams to check your liver hemangioma periodically for growth if the hemangioma is large.
However, some hemangiomas do not have these stereotypical characteristics. Atypical hemangiomas, which may vary in appearance, include those that are hypointense on T1-weighted images but retain the typical characteristics on T2-weighted and fat-suppressed postcontrast images (2).
Are atypical hemangiomas common?
VH are the most common spine tumors with an estimated incidence of 1.9-27% in the general population. Rarely, vertebral hemangiomas can exhibit extraosseous expansion with resulting compression of the spinal cord.
Can liver hemangiomas turn cancerous?
Liver hemangiomas are the most common type of benign liver lesions. They’re made up of tangled clumps of blood vessels. Most don’t cause symptoms and don’t need to be removed. They don’t turn into cancerous tumors.
Is an atypical hemangioma a tumor?
Hemangiomas are noncancerous (benign) tumors made of abnormal blood vessels. They’re common and can occur anywhere in the body: your skin, muscles, internal organs or bones.
Can liver hemangiomas be cancerous?
Although many people refer to them as tumors, hemangiomas are not malignant and do not become cancerous. There is no evidence to suggest that people who do not treat a liver hemangioma can develop liver cancer.
Can a hemangioma be cancerous?

What size liver hemangioma should be removed?
TAE is recommended to reduce hemangioma size, especially when the tumor is larger than 20 cm in diameter [13,14,15,16], and is used in cases of preoperative hepatic hemangioma rupture [17].
Can a hemangioma become cancerous?
Most hemangiomas occur on the surface of the skin or just beneath it. They often develop on the face and neck, and can vary greatly in color, shape, and size. Because hemangiomas very rarely become cancerous, most do not require any medical treatment.
