The splenic lymph nodes are found at the splenic hilum and in relation to the tail of the pancreas (pancreaticolienal lymph nodes). [1] [2] Their afferents are derived from the stomach, spleen, and pancreas. The splenic lymph nodes empty into the suprapancreatic, infrapancreatic and omental lymph nodes, which then drain to the coeliac nodes and ...
Splenic infarct appears as a wedge-shaped area of splenic tissue with the apex pointed toward the hilum and the base of the splenic capsule. As the infarction matures, the affected tissue may normalize, liquefy or become contracted or scarred. Abdominal ultrasound has also been used to detect splenic infarction. Ultrasound findings of the ...
The most common locations for accessory spleens are the hilum of the spleen and adjacent to the tail of the pancreas. They may be found anywhere along the splenic vessels, in the gastrosplenic ligament , the splenorenal ligament , the walls of the stomach or intestines , [ 3 ] [ 4 ] the pancreatic tail , [ 5 ] [ 6 ] the greater omentum , [ 7 ...
Hilum of the liver. In human anatomy, the hilum (/ ˈ h aɪ l ə m /; pl.: hila), sometimes formerly called a hilus (/ ˈ h aɪ l ə s /; pl.: hili), is a depression or fissure where structures such as blood vessels and nerves enter an organ. Examples include: Hilum of kidney, admits the renal artery, vein, ureter, and nerves
Enlargement of the spleen is a requirement for the diagnosis of SMZL and is seen in nearly all people affected by SMZL (often without lymphadenopathy). [1] Aside from the uniform involvement of the spleen, the bone marrow is frequently positive in patients with SMZL displaying a nodular pattern with morphology similar to what is observed in the splenic hilar lymph nodes.

The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein. Roughly, the portal venous system corresponds to areas supplied by the celiac trunk , the superior mesenteric artery , and the inferior mesenteric artery .
Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm, after aneurysms of the abdominal aorta and iliac arteries. [2] [3] They may occur in pregnant women in the third trimester and rupture carries a maternal mortality of greater than 50% and a fetal mortality of 70 to 90%.
The smaller veins unite to form larger veins that do not accompany the arteries, but soon enter the trabecular sheaths of the capsule, and by their junction form six or more branches, which emerge from the splenic hilum, and, uniting, constitute the splenic vein, the largest radicle of the portal vein.
