Diagnostic Ultrasound - Abdomen and Pelvis
Spleen Fat in splenic hilum Left hemidiaphragm Spleen CT CORRELATION Anatomy: Abdomen Tail of pancreas Left hemidiaphragm Renal pyramids Spleen Left kidney Left psoas muscle Stomach Left hemidiaphragm Spleen Splenic vein Accessory spleen (Top) Oblique correlative multiplanar reconstruction CT of the spleen is shown. Note the fat around the splenic hilum and the extension of the pancreatic tail towards the splenic hilum. This allows the pancreatic tail to be visualized by ultrasound using the spleen as an acoustic window. (Middle) Oblique correlative multiplanar reconstruction CT shows the relationship between the spleen and the kidney. (Bottom) Oblique correlative multiplanar reconstruction CT of the accessory spleen in the splenic hilum is shown. The accessory spleen simulates the appearance of a normal spleen on imaging; this identical appearance prevents it from being mistaken for pathology. 33
Spleen Anatomy: Abdomen SPLENIC VESSELS Left hepatic lobe Pancreas Left renal vein Inferior vena cava Splenic vein Superior mesenteric artery (SMA) Aorta Splenic vein Superior mesenteric artery Left renal vein Aorta Left hepatic lobe Splenic artery Common hepatic artery Portal vein Inferior vena cava Splenic vein Celiac artery Abdominal aorta (Top) Midline transverse anterior grayscale ultrasound of the splenic vein is shown. The splenic vein is located deep to the pancreatic body. Note the left renal vein course between the SMA and aorta. (Middle) Color Doppler of the same area shows the normal direction of flow in the splenic vein, towards the liver (hepatopetal). Note the change in color from red to blue, which is due to the position of the transducer, aligned at the midpoint of the vein. Using the information provided by the color bar, the red portion of the splenic vein is blood flowing towards the transducer (away from the spleen), and the blue is blood flowing away from the transducer (towards the the liver). (Bottom) Power Doppler of the upper abdomen at midline shows the origin of the splenic artery from the celiac axis. The celiac artery branches into the splenic artery, common hepatic artery, and left gastric artery (not shown). After its takeoff, the splenic artery typically has a tortuous course. The branching of the celiac axis, as shown in this image, has been referred to as the "seagull" sign. 34
