Medial Orientation of the Splenic Gastric Impression

Description

Medial (visceral) surface of the spleen is presented with emphasis on the facies gastrica, the broad concave gastric impression formed by the fundus and proximal body of the stomach. The depression occupies the anterosuperior portion of the medial surface, while the splenic hilum lies more medial and slightly inferior, interrupting the visceral contour where the splenic vessels enter and leave. Along the posterior part of this surface, the relationship trends toward the renal impression, with the intervening ridge reflecting the change in contact from stomach to left kidney. Curvature and contact anatomy are the story here. Gastric impression anatomy matters when you are correlating physical relationships with imaging and operative findings in the left upper quadrant. Fundal distension or acute gastric dilatation can alter splenic position and tension on the gastrosplenic ligament, a setup that increases concern for traction-related splenic capsular injury during upper GI surgery or difficult endoscopy. The same topography guides interpretation of splenic displacement by subphrenic collections and helps explain why left diaphragmatic irritation from perisplenic fluid can coexist with proximal gastric symptoms. Small landmarks, real consequences. Use this view in gross anatomy and abdominal viscera labs to teach the logic of visceral impressions, and in surgical education for laparoscopic fundoplication, sleeve gastrectomy, or splenectomy planning where the hilum and stomach adjacency drive safe dissection planes. It also fits radiology teaching files for CT correlation of stomach fundus position against the splenic medial surface, including cases of perigastric mass effect.
