Organ-associated pseudosarcomatous myofibroblastic proliferation with ossification in the lower pole of the kidney mimicking renal pelvic carcinoma: A case report

Figure 1 Imaging examination of our case of renal organ-associated pseudosarcomatous myofibroblastic proliferation. A: Computed tomography showed a heterogeneous mass (indicated with arrows) of 6 cm in diameter at the left pyeloureteral junction; B: Magnetic resonance imaging showed that the left renal pelvis was occupied by a cystic and solid mass (indicated with arrows) with calcification or ossification.
