Radioembolization of the spleen: a revisited approach for the treatment of malignant lymphomatous splenomegaly

Abstract

Intraarterial administration of (90)Y microspheres to the spleen in patients with malignant lymphoma was mentioned once in the literature in 1973. This case study illustrates the potential indication of selective internal radiotherapy in a heavily pretreated patient with highly refractory disease with a marginal zone lymphoma in leukemic phase and symptomatic splenomegaly. We describe the clinical course of disease; the biological and clinical response to the treatment after radioembolization; and simulation and dosimetry by multimodal imaging via single-photon emission computed tomography and computed tomography. The advantages of radioembolization for the management of lymphomatous splenomegaly are discussed.
