What is it
Hemangioma consists of cavities filled with blood and lined with vascular cells; The cavernous variant is more common. It apparently forms in utero as a vascular malformation, and is discovered by chance in adulthood. Most formations do not exceed a few centimeters and remain unchanged for years. Large hemangiomas are called hemangiomas more than five centimeters, and giant hemangiomas are more than ten centimeters, but even they often proceed calmly. It is important to understand: hemangioma does not affect liver function, does not cause an increase in liver enzymes and does not turn into a malignant tumor.
- A tangle of dilated vessels in the liver
- Most often congenital vascular anomaly
- Usually small and stable
- Large is considered more than 5 cm
- Does not affect liver tests
- Doesn't turn into cancer
Symptoms
The vast majority of hemangiomas do not manifest themselves in any way and remain an incidental finding. Complaints are possible if they are large in size, when the formation stretches the liver capsule or compresses neighboring organs: then dull heaviness and aching pain in the right hypochondrium, a feeling of fullness after eating, and sometimes nausea appear. Complications are rare: bleeding into the mass causes increased pain, and rupture with bleeding is an extremely rare event, usually associated with abdominal trauma. If a person with a hemangioma experiences jaundice, weight loss, or persistent pain, look for another cause for these symptoms.
- Most often asymptomatic
- Heaviness and aching pain on the right side with large sizes
- Feeling full after eating
- Increased pain with hemorrhage into the mass
- Rupture is an extremely rare complication, usually after injury
How is the diagnosis confirmed?
On ultrasound, a typical hemangioma looks like a homogeneous formation with clear, even contours, and in a person without risk factors this is often enough. If the size is significant, the picture is atypical, or there is a history of cancer, a clarifying study is prescribed. Magnetic resonance imaging with contrast is most revealing; contrast accumulation is characteristic from the periphery to the center; Multiphase computed tomography is also informative. Biopsy for suspected hemangioma is not usually performed due to the risk of bleeding and is not required when the imaging pattern is typical.
- Ultrasound of the liver as the first method
- Magnetic resonance imaging with contrast
- Multiphase computed tomography
- Characteristic type of contrast accumulation
- Liver tests to rule out other causes
- Biopsy is usually not indicated
Is treatment and observation necessary?
In most cases, hemangioma does not require any treatment. With a typical picture and small size, a single confirmation of the diagnosis is sufficient, sometimes with a control ultrasound after 6–12 months; If stable, further regular monitoring is often not necessary. Large formations are observed more often. No drugs, herbs or supplements will reduce hemangioma, and “liver cleanses” are useless and unsafe. There are no dietary restrictions. It is wise to avoid abdominal trauma and contact sports for really large lesions, and to report hemangioma to your doctor before surgery and examinations.
- Most often, confirmation of the diagnosis is sufficient
- Control ultrasound for large sizes
- There are no medications that reduce hemangioma
- No dietary restrictions
- Be careful with abdominal injuries with giant masses
- Report findings to physicians during other procedures
When is surgery considered?
Surgical treatment is discussed rarely and for specific indications: persistent pain clearly associated with the formation, rapid growth, compression of the bile ducts or blood vessels, complications such as bleeding, and the inability to exclude a malignant tumor. Options include removal of the formation, resection of part of the liver, and in some cases embolization of feeding vessels. The decision is made by the surgeon and gastroenterologist jointly, weighing the risk of intervention and the real benefits. Size itself without symptoms is usually not a reason for surgery, so “remove just in case” is the wrong tactic.
- Persistent pain associated with mass
- Rapid growth under control
- Compression of the bile ducts and vessels
- Complications with bleeding
- Inability to exclude malignancy
- Size without symptoms is not a reason for surgery
