A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
A cavernous liver hemangioma or hepatic hemangioma is a benign tumour of the liver composed of hepatic endothelial cells. It is the most common liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging. Liver hemangiomas are thought to be congenital in origin. [10]
Cavernous hemangiomas located in the brain or spinal cord are referred to as cerebral cavernomas or more usually as cerebral cavernous malformations (CCMs), [13] [2] and can be found in the white matter, but often abut the cerebral cortex. When they contact the cortex, they can represent a potential seizure focus for the patient.
Cavernous hemangiomas (also called hepatic hemangioma or liver hemangioma) are the most common type of benign liver tumor, found in 3%– 10% of people. [2] They are made up of blood clusters that are surrounded by endothelial cells. [5] These hemangiomas get their blood supply from the hepatic artery and its branches. [5]
An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. [1] [2] Other names include capillary hemangioma, [6] "strawberry hemangioma", [7]: 593 strawberry birthmark [8] and strawberry nevus. [6] and formerly known as a cavernous hemangioma.
Focal nodular hyperplasia is not a neoplasm; it is believed to result from localized hyperplastic hepatocyte response to an underlying congenital arteriovenous malformation. [2] It consists of normal liver constituents in an abnormally organized pattern, grows in a stellate pattern and may display central necrosis when large. [5]
An infantile hemangioma, also called a strawberry angioma, on a child's arm. Angiomas usually appear at or near the surface of the skin anywhere on the body, and may be considered bothersome depending on their location. However, they may be present as symptoms of another more serious disorder, such as cirrhosis. When they are removed, it is ...
[2]: 601 However, EPA has involved the testicle, [6] [9] deep muscle tissue as a neoplastic transformation of a larger existing benign cavernous hemangioma, [10] bone [11] and spleen, and has been found in adults. [7] [11] [12] Some reports indicate a good prognosis [13] but metastasis is occasionally seen.
