Figure 1
Figure 1 Ultrasonography and computed tomography (CT) of the splenic lesion. A: Gray-scale ultrasonography shows a homogenous and hypoechoic mass at the mid-portion of the spleen; B: Color Doppler sonography shows multiple color circular flow signals within the mass; C: CT shows a slightly lower-density mass in the spleen (arrows); D: The mass demonstrated strong enhancement after the intravenous administration of contrast material.
Figure 2
Figure 2 Magnetic resonance imaging (MRI) of the splenic lesion. A: T1-weighted MRI shows the isointense mass (arrows); B: The mass is mildly hyperintense in the T2-weighted MRI; C: The early phase of dynamic MRI shows diffuse heterogeneous enhancement of the mass; D: The mass becomes more enhanced during the delayed phase.

Figure 3 Macroscopic appearance of the resected spleen showing a circumscribed mass measuring 2. 5 cm × 2.4 cm in diameter (arrows).
Figure 4
Figure 4 Pathology of the splenic lesion. A: Microscopically, the mass is composed of predominantly a red pulp splenic sinusoidal structure accompanied by lymphocytes and macrophages. Atypical cells or mitosis were not observed; B: The endothelial cells lining the sinusoidal structure are immunoreactive for CD8.
