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.
It is a crescent-shaped space, encompassed by the lower edge of the left lung, the anterior border of the spleen, the left costal margin and the inferior margin of the left lobe of the liver. Thus, its surface markings are respectively the left sixth rib superiorly, the left mid axillary line laterally, and the left costal margin inferiorly.
A person can puncture their spleen if they crack their rib. Because there is a strong flow of blood in the spleen, there is a higher chance of excessive bleeding. Cirrhosis is a complication of many liver diseases characterized by abnormal structure and function of the liver. The diseases that lead to cirrhosis do so because they injure and ...
Abdominal ultrasonography of the liver, as a sagittal plane through the midclavicular line, with some standard measurements [2] Right lobe of the liver at the midclavicular line at ages 0 to 7 [16] Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span.
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 ...

The spleen is a lymphatic organ, which means it is largely involved in the immune system and immune responses. When the spleen becomes enlarged, it is a strong sign of infection somewhere in the body and can be caused by inflammatory conditions such as rheumatoid arthritis.
The left colic flexure or splenic flexure (as it is close to the spleen) is the sharp bend between the transverse colon and the descending colon.The splenic flexure receives dual blood supply from the terminal branches of the superior mesenteric artery and the inferior mesenteric artery.
