Spleen of an Elderly White Male, Gross Anatomy

Description

Framed within a semi-transparent anterior view of an elderly male torso, the spleen appears in the left upper quadrant, tucked deep to ribs 9 through 11 and lying lateral to the gastric fundus and superolateral to the left colic flexure. Its smooth diaphragmatic surface faces posterolaterally toward the diaphragm, while the visceral surface turns medially toward the stomach, left kidney, and tail of the pancreas at the hilum. Superiorly it sits under the left hemidiaphragm adjacent to the basal lung, and inferiorly it tapers toward the costal margin. Orientation is easy to read against the rib cage, vertebral column, and upper abdominal viscera. That diaphragmatic surface matters in blunt thoracoabdominal trauma, where left lower rib fractures and sudden rises in intra-abdominal pressure can lacerate splenic parenchyma and precipitate intraperitoneal hemorrhage. Surgeons also teach splenectomy planning from these relationships, because mobilization along the splenorenal and gastrosplenic ligaments brings the splenic hilum into view where the splenic artery and vein course near the pancreatic tail. Age context is clinically relevant. The elderly spleen may be smaller and more friable, and prior infarcts or capsular adhesions can alter operative planes. Use this full-body layout to anchor lectures in gross anatomy and radiologic correlation, pairing the organ position with CT abdomen teaching points and with physical exam discussions of when splenomegaly becomes palpable below the left costal margin. It also fits patient-facing materials explaining left upper quadrant pain after trauma, or publisher diagrams introducing lymphatic and reticuloendothelial filtration in systemic physiology.
