As portal hypertension sets in, there is resistance to venous outflow with subsequent development of venous congestion in spleen attributable to erythrocyte accumulation within the red pulp of spleen. Since vascular impedance depends on arterial resistance, venous compliance and venous congestion, an increase in venous congestion within the spleen leads to reduced diastolic velocities in the splenic artery and subsequently elevated resistance indices20.
The red pulp of spleen was replaced by a proliferation of lymphoid cells and a high concentration of neoplastic cells resembling the germ tumor cells found in the testis.
