Male, 6 years old, with neuroblastoma, off therapy evaluation. Assess for progression of disease. Lobular enhancing masses are again seen within the anterior paraspinal tissues bilaterally.On the left, tumor becomes apparent first at the T4 level continuing down to the T10 level. There has been no change in craniocaudal extent. Likewise, the maximal transaxial dimension is not significant changed at 26 x 18 mm.On the right, tumor is redemonstrated within the right T4-5 neural foramen and extending between the fourth and fifth ribs. Tumor is also evident extending between the fifth and sixth ribs. This latter lesion measures 23 x 10 mm which, again, is not significantly changed from prior.No evidence of any new lesion is detected. A mild scoliotic deformity is evident. Spinal alignment, vertebral body morphology and marrow signal characteristics are otherwise unremarkable. Mildly prominent mediastinal and right hilar lymph nodes are unchanged and nonspecific.
Stable bilateral anterior paraspinal masses are seen with no evidence to suggest any new or progressive lesions.
