Medial Representation of the Splenic Pancreatic Impression

Description

Medial aspect of the spleen is rendered with attention to its visceral (gastric) surface, where the impressio pancreatica forms a shallow concavity along the inferomedial region near the splenic hilum. The pancreatic tail lies medial to the splenic parenchyma, approaching the spleen within the splenorenal (lienorenal) ligament, so the resulting pancreatic impression sits posterior to the gastric impression and superior to the colic impression. Hilary landmarks for entry and exit of the splenic artery and vein frame this area, and the relationship to the left kidney and suprarenal region is implied by the medial orientation. Subtle topography matters here. Recognizing the splenic pancreatic impression has practical value when teaching how the pancreatic tail reaches the left upper quadrant and why it is the portion of the pancreas most closely associated with the spleen. In distal pancreatectomy, mobilization of the splenic flexure and division of the splenorenal attachments bring the surgeon directly into this plane, where the splenic vessels and short gastric vessels dictate whether a spleen-preserving approach is feasible. Radiologically, this relationship helps explain why pancreatic tail lesions can abut the splenic hilum and why splenic vein thrombosis from pancreatitis may present with left-sided portal hypertension and isolated gastric varices. Use this artwork in gross anatomy lab manuals, abdominal viscera lectures, and atlas plates that distinguish visceral surface impressions (impressiones) of the spleen with Terminologia Anatomica nomenclature. It also fits surgical education content on left upper quadrant approaches and imaging teaching files correlating organ impressions with CT and MRI anatomy.
