Abstract
The spleen can be affected by a variety of diseases. Some of them are readily identified as variations of normal or benign diseases on imaging. However, for a substantial number of focal splenic abnormalities, the diagnosis can be difficult so that histopathologic analysis may be required for a definite diagnosis. In this review, the typical splenic abnormalities that can be diagnosed with imaging with a high degree of confidence are illustrated. The complementary role of computed tomography (CT), magnetic resonance imaging and positron emission tomography/CT that helps make a diagnostic approach is discussed. Finally, current applications and future trends of radiomics and artificial intelligence for the diagnosis of splenic diseases are addressed.

Abstract
Splenic hamartoma (SH) is a rare, benign lesion. We present 2 cases, both in females (2 and 30 years, respectively) with multiple urinary tract infections, and left upper quadrant abdominal pain. Immunohistochemical staining with factor VIII displayed intense diffuse staining in the SH with corresponding weak staining in the adjacent spleen. CD31 showed a reverse pattern from that of factor VIII. CD34 staining pattern was identical in both the spleen and the SH. Ultrastructurally, the SH showed endothelial cells with relatively empty cytoplasm, scattered Weibel Palade bodies, and lining by basement membrane surrounded by fibrous long-spacing collagen. Our study highlights the unique immunohistochemical profile of SH. The ultrastructural features are interesting, although their diagnostic significance remains to be confirmed in future studies.
