A Case of Retroperitoneal Synovial Sarcoma in Pregnancy Treated with Antepartum Doxorubicin plus Ifosfamide Chemotherapy

Figure 1

Radiology of synovial sarcoma case. Magnetic resonance imaging prior to treatment (a, b) demonstrating the large retroperitoneal mass. (a) Fluid sensitive axial image shows the mass partially encasing the abdominal aorta and compressing and displacing the inferior vena cava. Mild right hydronephrosis is evident. (b) T2 coronal image showing extensive encasement of the aorta and right renal artery by the large retroperitoneal mass. Computed tomography imaging post 3 cycles (c, d) and 6 cycles (e, f) of neoadjuvant chemotherapy demonstrating treatment response as evidenced by marked decrease in tumor size, decreased mass effect on the vena cava, resolution of right hydronephrosis, and deceased tumor density (suggestive of necrosis).
