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 ...
Other causes of splenomegaly (for example, Gaucher disease or hemoglobinopathies) can also predispose to infarction. Splenic infarction can also result from a sickle cell crisis in patients with sickle cell anemia. Both splenomegaly and a tendency towards clot formation feature in this condition.
All people with ALPS have signs of lymphoproliferation, which makes it the most common clinical manifestation of the disease. The increased proliferation of lymphoid cells can cause the size of lymphoid organs such as the lymph nodes and spleen to increase (lymphadenopathy and splenomegaly, present in respectively over 90% and over 80% of patients).
There is no real treatment for Felty's syndrome, rather the best method in management of the disease is to control the underlying rheumatoid arthritis. Immunosuppressive therapy for RA often improves granulocytopenia and splenomegaly; this finding reflects the fact that Felty's syndrome is an immune-mediated disease.
Splenomegaly can result in hematologic disturbances and abdominal pain and can increase the risk for splenic rupture, which also causes spleen pain, from blunt trauma, resulting in life-threatening internal bleeding. [2] Many conditions can cause splenomegaly, such as various infections, liver disease, and cancer. [2]
Splenomegaly: Medical imaging: Largest dimension of over 11 cm, [27] [28] or craniocaudal height of 13 [29] cm. Moderate splenomegaly: the largest dimension is between 11–20 cm [27] Severe splenomegaly: the largest dimension is greater than 20 cm [27] Autopsy: Weight over upper limit of standard reference range, of 230 g (8.1 oz) [12] [13 ...
Hepatosplenomegaly (commonly abbreviated HSM) is the simultaneous enlargement of both the liver (hepatomegaly) and the spleen (splenomegaly).Hepatosplenomegaly can occur as the result of acute viral hepatitis, infectious mononucleosis, and histoplasmosis or it can be the sign of a serious and life-threatening lysosomal storage disease.
The basic pathology is some kind of obstructive pathology in the portal, hepatic or splenic vein that causes obstruction of venous blood flow from the spleen towards the heart. The cause of such obstruction may be abnormalities present at birth (congenital) of certain veins, blood clots, or various underlying disorders causing inflammation and ...
