Accessory spleen is a manifestation of congenital abnormal spleen development. It is the growth of spleen-like tissue in addition to the spleen. Surgical excision is required. This is not a good sign.

Accessory spleen refers to a congenital ectopic spleen tissue that exists outside the normal spleen and is structurally similar and functionally identical to the spleen.

Accessory spleen is less rare, occurring in about 10% to 30% of cases. Most accessory spleens are present near the hilum of the spleen, and in some cases also occur near the splenic pedicle or splenic vessels, or the tail of the pancreas. The accessory spleen is an important tissue structure because in some cases, such as when the patient has a traumatic splenic rupture and needs to have the spleen removed, the preservation of the accessory spleen is important for the patient.

Causes and diagnosis of accessory spleen1. The accessory spleen is caused by congenital dysplasia.

2. Failure of primitive splenic-bud fusion during embryonic development.

3. Ectopic splenic bud formation during embryonic development.

4. During embryonic development, part of the spleen bud is separated from the main spleen.

The main tests to confirm the diagnosis of accessory spleen are abdominal ultrasound, abdominal CT and other imaging examinations. The interior is a uniform fine punctate echo, and the echo intensity is similar to that of the main spleen, and the boundary with the main spleen is clear. The accessory spleen appeared round or quasi-circular in the thin-slice CT of the abdomen, with clear boundaries and uniform density, and was significantly uniformly enhanced after enhancement, and the density of the main spleen was similar to that of the main spleen on noncontrast and contrast-enhanced scans.

Hello, check hepatitis B five items, if the surface antibody of hepatitis B, that is, the second item is positive, it means that the hepatitis B infection has been cured or hepatitis B vaccine has been injected, this situation is not needed.

If one or more of the other tests are positive, it means that you are infected with hepatitis B, and you need to check your liver function and hepatitis B DNA, and if there is any abnormality, you need to protect yourself and be antiviral**.

3. The spleen is ascending and clearing: rising, for rising and losing cloth; Qing is a subtle substance. This means that the spleen has the function of absorbing nutrients such as water valley subtleties and infusing them to the heart, lungs, and leaders, and then transforming qi and blood through the action of the heart and lungs to nourish the whole body and maintain a relatively constant position of the internal organs of the human body.

The accessory spleen is something that grows outside the spleen and has the same composition as the spleen. Usually from the accessory spleen dress mechanism mechanism, location, symptoms, etc., if the body due to the accessory spleen abnormal performance, should be timely medical examination, and the corresponding **.

1. Mechanism of occurrence.

Accessory spleen refers to the formation of organs similar to the normal spleen structure and function when one or several interstitial cell masses cannot be fused with the spleen, and the blood supply of the accessory spleen mainly comes from the splenic artery, and in most cases no abnormal changes occur;

2. Location. It is more common in the location of the splenic antle, and can also appear in the spleen pedicle, omentum and other parts, or distal metastasis to mesenteric ovaries and other parts;

3. Symptoms. Most have no symptoms. There is also the possibility of abnormal lesions such as rupture, hemorrhage, hyperplasia, infarction, etc., which are manifested as hemolytic anemia symptoms such as headache, fatigue, jaundice, splenomegaly, and fever.

Episplenic hyperplasia, rupture, or bleeding may cause symptoms of hypovolemia such as vague epigastric pain, rapid pulse, and dizziness. When the parasplenic is embolized or infarcted, it is manifested as severe epigastric pain that may radiate to the left shoulder, or accompanied by symptoms such as nausea and vomiting.

4. Inspection. Accessory spleen is usually discovered incidentally during ultrasonography or surgery of other abdominal organs. CT shows round or oval nodules, resembling lymph nodes. MRI can help distinguish the accessory spleen from other abdominal masses;

5、**。Symptomatic accessory spleen usually does not need to be surgified**, and surgical resection should be performed in the event of complications such as intestinal obstruction, splenic rupture and bleeding**. In addition, because the accessory spleen is supplied to the splenic artery, if the hematologic disorder causes hypersplenism, the accessory spleen needs to be removed along with the spleen, and in other cases the accessory spleen is usually preserved.
