Perinephric Extramedullary Hematopoiesis

Fig. 8-186. Perirenal extramedullary hematopoiesis in a patient with agnogenic myeloid metaplasia (idiopathic myelofibrosis).

(a) CT and (b) coronal Tl-weighted MR scan demonstrate bilateral perirenal tissue (arrowheads) with distinguishable nodules of extramedullary hematopoiesis (open arrow). Needle biopsy confirmed the presence of hemopoietic tissue. There is severe splenomegaly with splenic nodules of extramedullary hematopoiesis (black arrow), hepatomegaly, and osteomyelosclerosis of the vertebral bodies. (Reproduced from Rapezz et al.257)
