|Patient: 1 year 9 month 17 day old female|
|History: 21-month-old infant girl who has had salvage chemotherapy for recurrent neuroblastoma. Imaging is requested to evaluate extent of disease.|
|Findings: MIBG findings: Increased uptake in a left paraspinal mass in the lower abdomen that is unchanged and that correlates with a mass on CT. There is also a linear area of activity just medial to the left paraspinal mass that is unchanged and that correlates with extension of the mass into the spinal canal on the CT images.|
MR findings: Large left paraspinal mass demonstrating diffuse homogeneous contrast enhancement. Again this measures 3.3 x 2.6 x 6.6 cm. There is an intraspinal component to the mass which is also unchanged in size and measures approximately 2.2 cm transverse. The mass extends into the spinal canal from T12 to S1 and involves the neural foramen on the left side at T12-L1, L1-L2, and L2-L3. The portion of the mass which is within the spinal canal displaces the thecal sac to the right and spinal cord and cauda equina are removed into the right lateral recess. A masslike configuration of the matted nerve roots at the cauda equina is unchanged.
|Diagnosis: Spinal extension of metastatic neuroblastoma.|
