Extramedullary hematopoiesis (EMH) has been reported in various organs. However, its manifesta-tion as a focal tumor-like splenic lesion is rare. Here, we report a case of EMH in an 85-year-old female presenting as a well-defined intrasplemic mass of 12cm on sonography and computed tomography. Splenectomy was performed under the impression of splenic tumor,and intrasplenic focl EMH was diag-nosed histopathologically.
