A rare case of suspected intravascular large B-cell lymphoma forming nodular masses in the brain and around the prostate and seminal vesicle

Abstract

Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of diffuse large B-cell lymphoma (DLBCL). Furthermore, tumorigenesis is extremely rare. An 80-year-old man was admitted to our hospital with nervous symptoms. Imaging tests showed a brain tumor and mass lesions in the seminal vesicle and retroperitoneum. Transrectal biopsy of the seminal vesicle helped diagnose the patient with DLBCL. The patient's general status deteriorated rapidly, and he died on the 23rd day after admission. An autopsy was performed and the pathological diagnosis was DLBCL, specifically suspected as IVLBCL, with nodular masses in the brain and seminal vesicle.
