title: Epidermoid cysts of the spleen.
abstract: In the two cases presented here, the sonographic findings were unique. At low gain settings the rounded masses appeared sonolucent and smooth walled. As the gain was increased, multiple internal echoes appeared close to the inner wall, indicating the thick and irregular wall lining. It is presumed that these echoes were produced by the trabeculae. It is felt that the sonographic findings in epidermoid cysts of the spleen may be diagnostic, obviating the need for arteriography.
