Overview
A hepatic hemangioma is a noncancerous liver tumor made of dilated (widened) blood vessels and is the most common primary liver tumor.
Historical Perspective
Classification
Pathophysiology
- They arise from the endothelial cells that line the blood vessels and consists of multiple, large vascular channels lined by a single layer of endothelial cells and supported by collagenous walls.
Causes
There are no established causes for hepatic hemangioma.[1]
Epidemiology and Demographics
Prevalence
- The prevalence of hepatic hemangioma is up to 7% in normal adult population.[2]
Risk factors
Screening
Differentiating Hepatic hemangioma from other Diseases
Hepatic hemangioma must be differentiated from other diseases such as hepatic metastases, hepatocellular carcinoma, hepatic cyst.[3]
Natural History, Complications and Prognosis
Diagnosis
Physical Examination
They are frequently asymptomatic and incidentally discovered at imaging, surgery, or autopsy. Hepatic hemangioma is usually not discovered until medical pictures are taken of the liver for some other reason. If a cavernous hemangioma ruptures, the only sign may be an enlarged liver.
Laboratory Findings
Findings consistent with anemia (hemolytic anemia) are evident.
Treatment
