Diagnostic Ultrasound - Abdomen and Pelvis
Peritoneal Spaces and Structures Liver RIGHT SUPRAMESOCOLIC SPACE: LESSER SAC Anatomy: Abdomen Stomach Pancreas Superior mesenteric artery Abdominal aorta Lesser sac loculated collection (with artifactual echoes) Splenic vein Left lobe of liver Fluid in lesser sac Stomach with fluid Fluid in lesser sac Splenic vein Aorta Pancreas Right subphrenic space Anasarca Hepatorenal fossa fluid Left lobe of liver transplant Left anterior perihepatic space Lesser sac fluid Colon Tip of spleen Posterior perisplenic space Perisplenic collaterals (Top) Subxiphoid transverse grayscale ultrasound shows a fluid collection in the lesser sac, which extends to the left, behind the stomach and anterior to the pancreas. The lesser sac is part of the right supramesocolic space and communicates with the rest of the peritoneal cavity through the epiploic foramen (of Winslow). (Middle) Subxiphoid transverse color Doppler ultrasound of the same patient shows moderate fluid in the lesser sac posterior to the stomach. The splenic vein was dilated in this patient, with portal hypertension status post liver transplant. (Bottom) Axial CECT of the same patient shows fluid in the lesser sac and peritoneal cavity, as well as diffuse anasarca. 93
Peritoneal Spaces and Structures Anatomy: Abdomen LEFT SUPRAMESOCOLIC SPACE Falciform ligament Fluid in supramesocolic space Left portal vein Caudate lobe Inferior vena cava Vertebral body Fluid in left subphrenic space Spleen Left hemidiaphragm Left kidney Left pleural effusion Left lobe of liver Lesser sac fluid Perisplenic fluid Septation Splenorenal ligament Inferior spleen (Top) Subxiphoid transverse grayscale ultrasound shows fluid anterior to the left lobe of the liver that is localized to the left, posterior subhepatic space. Incidental calculi are seen within a dilated intrahepatic biliary duct. (Middle) Longitudinal grayscale ultrasound of the left upper quadrant shows a small amount of perisplenic fluid extending under the left hemidiaphragm. The left subphrenic space is separated from the right subphrenic space by the falciform ligament. (Bottom) Transverse grayscale ultrasound of the left upper quadrant reveals fluid in the perisplenic space and lesser sac. 94
