What is cavernous hemangioma in the liver?
A liver hemangioma (he-man-jee-O-muh) is a noncancerous (benign) mass in the liver made up of a tangle of blood vessels. Also known as hepatic hemangiomas or cavernous hemangiomas, these liver masses are common and are estimated to occur in up to 20% of the population.
Is liver hemangioma life threatening?
In severe cases, a larger hemangioma can rupture. This can interfere with organ function and cause bleeding into the abdomen or widespread blood clotting. It can lead to heart failure and can be fatal.
Can cavernous hemangioma of the liver cause pain?
Hemangiomas greater than 4 cm, however, tend to cause abdominal pain and discomfort. The most common symptoms are right upper quadrant pain, generalized abdominal pain, or abdominal fullness.
Can cavernous hemangioma cause pain?
Cavernous angiomas in many parts of the brain and spinal cord can cause weakness or numbness in arms or legs. In some areas, such as the thalamus, they can also cause pain.

What is cavernous hemangioma?
Cavernous hemangiomas are vascular malformations characterized pathologically by large, thin-walled, and cystically dilated blood vessels. They are rare vascular tumors of the ocular surface; unlike capillary hemangioma, lymphangioma, and pyogenic granuloma which are more common. [1,2]
How reliable are Ultrasonographic findings in the diagnosis of hemangiomas?
While small hemangiomas (less than 3 cm) have a characteristic ultrasonographic appearance, lesions larger than 3 cm in diameter may have a whole host of ultrasonic findings and this technique becomes less reliable in making the diagnosis.
What are the complications of a hemangioma?
Complications depend on the size and location of the hemangioma, and include: Compression (pushing) against surrounding organs such as the stomach (leading to feelings of fullness soon after beginning a meal); bile ducts (leading to jaundice ); or the liver capsule (which causes pain)
