SEER Inquiry System - Question 20130148 Details

Are any of the following cases reportable?

Example 1: Clinical Diagnosis: Extradural spinal cord tumor compatible with schwannoma. What assumptions should be made about reportability if the tumor is described as being extradural? The extradural spinal cord includes epidural fat surrounding the thecal sac and exiting nerve roots. Does this mean there are not nerve roots in the extradural spinal cord?

Example 2: Final Pathologic Diagnosis: Designated "C3-4 nerve sheath tumor" excision: Morphologic and immunohistochemical findings consistent with cellular schwannoma. When stated to be a "nerve sheath tumor" does that mean peripheral nerve (C47_) involvement or nerve root (C72_) involvement?

Example 3: Final Pathologic Diagnosis: T-8 vertebral tumor resection: Schwannoma with degenerative changes (calcification, cyst formation) - ganglion and nerve are identified. There is no mention clinically or pathologically whether this tumor is "intradural" or "of the nerve root." In the absence of information about whether the location of the tumor is intradural or involving the nerve root, is it assumed that it does involve this part of the spinal cord when a specific vertebrae is removed?
