The Pathologic Spleen

  • Francis S. Weill

Abstract

The enlarged spleen is particularly easy to examine ultrasonographically, even if it does not extend beyond the costal margin. The criteria of splenomegaly have already been mentioned. The anteroposterior diameter of the spleen increases, the spleen extending from the region of the kidney to the left lobe of the liver (Figs.28.1–28.5). The extension of the spleen to the right may displace the left lobe of the liver (Figs. 28.2, 28.3, 28.6). The spleen also enlarges transversely. Its medial surface may become slightly convex (Figs. 28.1, 28.6). Transverse enlargement of the spleen may be accompanied by flattening of the left kidney (Fig. 28.7). The size of the spleen also increases along its craniocaudal axis, extending beyond the lower pole of the kidney. This appearance is demonstrated in coronal sections (Figs.28.3g, 28.7). Sagittal sections of the left upper quadrant may show the spleen extending under the left lobe of the liver (Fig. 28.8).
