Reportability--Brain and CNS: Are lipomas of the spinal column reportable as a benign tumor of the central nervous system (CNS)? This is seen occassionally at our pediatric facility.
Spinal cord tumors (including lipomas) are reportable when they arise in the spinal dura or nerve root. The tumor must be of the spinal cord itself or within the spinal cord dura. Spinal cord tumors are reportable when they arise in the intradural space. A reportable intradural tumor can be either intramedullary or extramedullary. Extramedullary intradural spinal tumors are reportable. A spinal tumor originating in the extradural space is not reportable. If it is outside the dura, it is not reportable because it would be outside the CNS. They are not reportable when they arise in the peripheral nerves.
