Massive hepatosplenomegaly before splenectomy. A) Magnetic resonance imaging (MRI) revealed enlargement of especially the spleen on axial projection. The splenic enlargement resulted in a compression of the bladder (H = Head, F = Foot, R = Right, L = Left). B) On sagittal MRI projection, compression of the left kidney was seen. The compression of other intraabdominal organs impeded alimentation (H = Head, F = Foot, A = Anterior, P = Posterior). C) On Doppler sonography, the portal vein was relatively prominent with a width of 1 cm. Portal vein blood flow was markedly increased. D) During surgery, the extent of splenomegaly was documented. The organ had a weight of 1.2 kg.
