Accessory spleens may be formed during embryonic development when some of the cells from the developing spleen are deposited along the path from the midline, where the spleen forms, over to its final location on the left side of the abdomen by the 9th–11th ribs. The most common locations for accessory spleens are the hilum of the spleen and ...
Polysplenia is a congenital disease manifested by multiple small accessory spleens, [1] rather than a single, full-sized, normal spleen.Polysplenia sometimes occurs alone, but it is often accompanied by other developmental abnormalities.
Splenosis in the abdominal category may occur in up to 65% of traumatic ruptures of the spleen. [3] Splenosis in the thoracic cavity is rarer, because it requires the simultaneous rupture of the diaphragm. The implantation of spleen tissue under the skin may result from abdominal surgery or gunshot wounds. Splenosis of the brain or liver is ...
Left testis in scrotal position with adherent accessory spleen. Splenogonadal fusion is separated into two types: Continuous (55%): The native spleen is connected to the gonad. The connection occurs through a cord of splenic tissue or fibrous band. Discontinuous (45%): Ectopic splenic tissue is present and attached to the gonad.
The spleen is 1 by 3 by 5 inches (3 by 8 by 13 cm), weighs approximately 7 oz (200 g), and lies between the ninth and eleventh ribs on the left-hand side and along the axis of the tenth rib. The weight varies between 1 oz (28 g) and 8 oz (230 g) (standard reference range ), [ 12 ] correlating mainly to height, body weight and degree of acute ...
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
Splenomegaly is an enlargement of the spleen. [1] The spleen usually lies in the left upper quadrant (LUQ) of the human abdomen.Splenomegaly is one of the four cardinal signs of hypersplenism which include: some reduction in number of circulating blood cells affecting granulocytes, erythrocytes or platelets in any combination; a compensatory proliferative response in the bone marrow; and the ...
Acquired asplenia occurs for several reasons: . Following splenectomy due to splenic rupture from trauma or because of tumor; After splenectomy with the goal of interfering with splenic function, as a treatment for diseases (e.g. idiopathic thrombocytopenic purpura, thalassemia, spherocytosis), in which the spleen's usual activity exacerbates the disease
