What causes massive splenomegaly?
The most common aetiologies of massive splenomegaly include haematological disorders (chronic myeloid leukamia, agnogenic myeloid metaplasia, polycythaemia vera, essential thrombocythaemia, indolent lymphomas, hairy cell leukaemia, β-thalassaemia major), infectious diseases (visceral leishmaniasis, malaria) and …
Does cirrhosis cause splenomegaly?
Liver disease such as cirrhosis, or liver scarring, can cause the blockage of blood flow through the liver, thus causing blood to back up in the portal vein resulting in increased pressure or portal hypertension. As a result, the spleen becomes engorged with blood, leading to splenomegaly.
Why does splenomegaly occur in cirrhosis?
In this condition, splenomegaly is not only caused by portal congestion, but it is mainly due to tissue hyperplasia and fibrosis. The increase in spleen size is followed by an increase in splenic blood flow, which participates in portal hypertension actively congesting the portal system.
What is massive splenomegaly?
Healthcare professionals consider splenomegaly when the spleen is anywhere from 12 to 20 centimeters (cm) (4.7 to 7.9 inches [in]) in length and weighs more than 400 grams (g) (0.88 pounds [lb]). Massive splenomegaly occurs when the spleen is larger than 20 cm (7.9 in) or weighs more than 1,000 g (2.2 lb).
Why does spleen enlarge with liver disease?
Enlargement of the liver can also cause enlargement of the spleen because the two organs are close to each other. When the liver increases in size, it places extra pressure on the spleen. This pressure affects blood flow to the spleen, which can cause it to swell and get bigger.
How does cirrhosis cause Hypersplenism?
Hypersplenism is a common complication in patients with chronic liver diseases, leading to decreases in platelet and hemoglobin levels, and correlates with the severity of cirrhosis. Splenomegaly is often used radiologically as an indicator of cirrhosis.
Is splenomegaly serious?
An enlarged spleen can reduce the number of healthy red blood cells, platelets and white cells in your bloodstream, leading to more frequent infections. Anemia and increased bleeding also are possible. Ruptured spleen. Even healthy spleens are soft and easily damaged, especially in car crashes.

May show hyponatraemia and azotaemia. The underlying cause for the liver disease can be determined by biopsy (Mallory bodies). Helpful in determining splenomegaly, especially in obese patients. In the presence of cirrhosis and portal hypertension, a biopsy is likely to add value or change management.

When to use the spleen in liver cirrhosis?
Clinically, splenomegaly has been associated with a poor prognosis in liver cirrhosis and utilized during radioactive or acoustic examinations as an index for the non-invasive assessment of esophageal varices and bleeding risks [ 1, 21, 22 ].
When to know if you have massive splenomegaly?
Massive splenomegaly is variably defined, including when the spleen is 5 standard deviations above the mean normal volume (about 943 cm 3 ) 4, heavier than 1000 g 5 or 1500 g 8, longer than 18 cm 8, or extending into the pelvis or across midline 4.
