Spontaneous regression of stage III neuroblastoma: A case report

Figure 2 The volume of the tumour (red part) was 193. 6 mL according to the three-dimensional reconstruction of the abdominal enhanced computed tomography images with a computer-assisted surgery system (Hisense CAS) upon admission. The boundary of the tumour was infiltrative. The tumour was surrounded by important retroperitoneal vessels such as the inferior vena cava, renal artery, renal vein, and abdominal aorta, as seen by rotating the three-dimensional images at any angle.
