?Introduction to the cavernous
Hemangioma

?

Cavernous Hemangioma of the liver (hepatic hemangioma) is a common
benign diseases of liver, soft texture, most clearly with the
adjacent tissue boundaries, manifested in the blue-violet anhong,
cystic uplift, solid leaf or nodular. Its causes are not that many
believe originated in the fetal liver and vascular Hamartoma bud,
there are also people who believe and estrogen levels, as a result of
the female morbidity related to men's 6 times. The disease can occur
at any age, as many as solitary, located in the right lobe of liver,
10% more fat, can be distributed on a single side or double side lobe
of liver. Peking Union Medical College Hospital liver surgery du

The disease develops slowly, the course can be up to several years to
decades, tumor hours without symptoms, more because of the physical
line imaging or other operative found. Small hemangiomas multiple
asymptomatic, increased cancer may be associated with compression,
abdominal discomfort, postprandial full zhanggan and other symptoms.
In addition, you can have with fibrous tissue, machine of thrombus,
can cause recurrent thrombosis induced liver tumours swelling,
retraction capsular swelling and pain. Rare tumor rupture can cause
hemorrhagic shock, acute abdominal symptoms. Small hemangiomas can be
formed in the liver, causing arteriovenous fistula return increase,
leads to congestive heart failure. Examination in general no obvious
signs, when the tumor is large, you can reach masses on the abdomen,
the surface is smooth, medium or soft lobulated, SAC sexy and
different levels of compression, typically no tenderness, or only
mild tenderness.

Cavernous Hemangioma in patients with liver function test, AFP,
hepatitis, antibodies and other aspects of performance as normal.
On a clinical diagnosis. Ultrasound-guided disease manifestations can
be divided into three types: echogenic model: this model is more
common, a round or oval, sharp edges or sharp echogenic light mission,
as many of the blood-the blood vessel wall interface of reflecting,
with characteristic. Internal echo into evenly distributed and not
even two, uneven light panel visible small solid network-like low
echo area, its ECHO slightly enhanced edge. This type of mixed type:
lack of clarity or fuzzy edges, unequal distribution of internal echo,
ECHO for strong and irregular anechoic zones. Cuff: sharpness,
echogenic band, internal to the irregular shape without ECHO.

CT, visible in solitary or multiple round or class circle of low
density range, clear the border, a few visible shadow small
calcification density, also visible in lower density anomaly.
Enhanced scanning most lesions are "fast forward and slow out of the"
substantive strengthening, reinforcement from edge to centre of
fibrosis or thrombosis part always low density. The different
manifestations and CT of the histological type, thin-walled-lacuna,
contrast agents into many stay longer and gradually disseminated,
could eventually be delay scans are density; thick-interval
organization more than small, contrast is not easy to enter or access,
performance-enhancement is not obvious or completely enhanced
performance hybrid '; some enhancements and some non-obvious enhanced
mixed lesions.

In T1-weighted MRI images on round or oval, smooth edge clear,
uniform low signal or signals in T2-weighted images for high signal
area, and with the echo time extended its signal, the signal in black
liver against the formation of a typical "bulb collection." Line scan,
dynamic contrast-enhanced Gd-DTPA lesions are significantly more
durable tempered, concentric focus is. Real increase and subsequent
is liver Hemangioma Super filling. T2-weighted as hepatic Hemangioma
on average higher than metastatic tumors and liver tissue can be used
as identification.

Radionuclide liver scanning: static scan liver lesions characterized
by sparse zones or radiation radiation defects; dynamic imaging
arterial and venous phase respectively to Imaging or image, but the
liver blood pool Imaging balance period of radioactive strength
higher than normal liver tissue, performance for the limitation,
clear excess filling zone. "Slow infusion" phenomenon is one of the
characteristic features of hepatic Hemangioma. But in recent years
follow-up ultrasound, CT, MRI applications increase and diagnostic
sensitivity and specificity of the application.
Diagnosis of hepatic angiography for Hemangioma, but because of their
traumatic, clinical application.

Cavernous Hemangioma is considered to be a benign tumor of the liver,
the tumor diameter "5cm, silent, without treatment, regular review
and follow-up; if there are obvious symptoms, near major vascular
tumors or cannot rule out the possibility of liver cancer, you may
consider surgery. Tumor diameter 5-10cm recommended elective surgical
resection of liver tumor is located; and as the edge of the
occurrence probability of traumatic rupture, it is recommended that
early surgery; tumor diameter > 10cm is usually suggested lines of
surgery, or liver transplantation. For patients with multiple
Hemangiomas, consider one with, or combined banding surgery. Surgical
excision including traditional open surgery, part of the necessary
joint open-chest, I section has extensive laparoscopic resection of
liver Hemangioma, greatly improved patient postoperative recovery.

If patients generally cannot withstand surgery, embolization can be
considered, but Interventional often cannot control the Hemangioma of
growth. At present some scholars begin using radio frequency, γ
knife, used to treat liver Hemangioma, Hemangioma of the relatively
large size of ineffective and long-term results.
