비장의 비외상성 양성병변

Abstract

The spleen is one of the largest organ in the reticuloendothelial system and plays an important role in theac-tivation of immune response. It is the organ most commonly injured after blunt abdominal trauma, and malig-nantlesions such as lymphoma, or these due to metastasis, occur not infrequently. Even so, it is ignored even inabdominal ultrasonography. Some benign splenic lesions, however can cause severe symptoms and result in high mortality, and their accurate diagnosis is therefore essential. This study describes the imaging findings andhistopathologic features of various nontraumatic benign splenic lesions.
