Liver Hemangioma

Hepatic hemangiomas have not been reported to undergo malignant transformation into liver cancers. Most hemangioma are not causing any symptoms (asymptomatic) and surgical liver resection is not necessary. However, some of them grow to a large size and cause mechanical pressure or compression to the liver capsule and/or other surrounding organs (stomach, small bowel, colon, diaphragm, chest wall, rib, bile ducts). A large hemangioma can cause dull right upper abdominal pain, persistent back pain, nausea, discomfort, and right shoulder pain. A large hemangioma that is close to the liver capsule leads to a slightly higher risk of bleeding with abdominal trauma.

Giant Hepatic Hemangioma

Hepatic hemangiomas are benign mesenchymal hepatic growths that often present as solitary lesions and are usually located in the right lobe. Depending on the size, they are characterized as capillary hemangiomas (<3 cm), medium hemangiomas (between 3 and 10 cm) and giant or cavernous hemangiomas (>10 cm)...

Hemangioma Liver Lesions

Hemangioma liver lesions are noncancerous, abnormal masses of tangled blood vessels found in the liver. Also referred to as hepatic hemangiomas and cavernous hemangiomas, a liver hemangioma will typically occur as a single collection of abnormal vessels. In rare cases, they may form as a group or cluster.

Hepatic hemangioma -review

Hepatic hemangiomas are benign tumors of the liver consisting of clusters of blood-filled cavities, lined by endothelial cells, fed by the hepatic artery. The vast majority of HH are asymptomatic, most often being discovered incidentally during imaging investigations for various unrelated pathologies.

Hepatic Hemangioma: Review of Imaging and Therapeutic Strategies

Hepatic hemangiomas are the most common benign liver tumors. Typically, small- to medium-sized hemangiomas are asymptomatic and discovered incidentally through the widespread use of imaging techniques. Giant hemangiomas (>5 cm) have a higher risk of complications. A variety of imaging methods are used for diagnosis. Cavernous hemangioma is the most frequent type, but radiologists must be aware of other varieties.

Hepatic Hemangioma: Understanding a Benign Liver Tumor

In many cases, hepatic hemangiomas do not cause any noticeable symptoms and are discovered incidentally during imaging tests for other conditions. However, in some instances, larger hepatic hemangiomas or those located in certain areas of the liver may cause symptoms...

Hepatic Hemangiomas: Spectrum of US Appearances on Gray-scale, Power Doppler, and Contrast-Enhanced US

Because US plays a key role in the initial evaluation of hepatic hemangiomas, knowledge of the entire spectrum of US appearances of these tumors is important. Most hemangiomas have a distinctive US appearance, and even with those with atypical appearances on conventional gray-scale US, specific diagnoses can be made using pulse-inversion harmonic US with contrast agents.

Infantile hepatic hemangiomas: looking backwards and forwards

Infantile hepatic hemangiomas (IHHs) are common benign tumors seen in the liver of infants. IHHs are true infantile hemangiomas (IHs) and have phases of proliferation and involution parallel to those of cutaneous IHs.

Natural history of hepatic hemangiomas as a guide for surgical indication

The majority of hepatic hemangiomas are asymptomatic and complications are rare. Hemangioma size alone is not indication for surgery in asymptomatic patients. Surgical indications are limited to patients with severe symptoms, complications, or suspicious lesion. Most hemangiomas, even giant hemangiomas, can be managed conservatively.

The Natural History and Management of Hepatic Hemangioma

Hepatic hemangiomas are the most common benign tumors of the liver. Most hemangiomas are small and asymptomatic; therefore, these tumors have little clinical significance and require no treatment. In view of this, little is known of the natural history and growth pattern of these tumors, and their appropriate management is still not clearly defined.

The Unexpected High Incidence of Hepatic Hemangiomas...

The use of grayscale ultrasonography is widely accepted for the detection of focal hepatic lesions. Hemangiomas are among the most common benign lesions and are frequently encountered as an incidental diagnostic finding.

Things to know about liver hemangiomas

Liver hemangioma presents as an incidental finding during abdominal ultrasound and is described as a solitary or multiple lesion. They may be limited to one lobe (more so in the right lobe) or extend to the entire liver. According to their size, they can be small or giant (>5 cm) and can be from 1 mm to 50 cm long. Liver hemangiomas are classified according to their nature as cavernous, capillary and sclerosing hemangiomas; The latter are characterized by degeneration and replacement of fibers and may be misdiagnosed as melanoma

What is changing in indications and treatment of hepatic hemangiomas. A review

Patients affected by hemangioma usually have their tumor diagnosed by ultrasound abdominal examination for a not well defined pain, but pain persist after treatment of the hemangioma. The causes of pain can be various gastrointestinal pathologies including cholelithiasis and peptic ulcer disease.The malignant trasformation is pratically inexistent.
