摘要
A 3-year-old boy presented with a rare case of spinal cord pilocytic astrocytoma. Total removal of the spinal cord tumor was impossible and chemotherapy was chosen for adjunctive therapy. He was given a craniotomy, temozolomide, and chemotherapy. Despite high overall response rates to chemotherapy in low-grade astrocytomas, MRI showed no significant tumor regression. An F-18 FDG PET/CT to evaluate treatment response showed an elongated hypermetabolic spinal cord tumor from C1 to T7. Intense FDG uptake indicated a significant residual pilocytic astrocytoma. Because of his poor response to chemotherapy, the patient was referred for radiotherapy.
