Schwannomas adherent to the spinal cord are rare and include both intramedullary (subpial) and combined intra- and extramedullary lesions. Here, a 60-year-old male initially presented with a combined intra\/extramedullary schwannoma with dense adhesions to the spinal cord; at surgery, this proved to be a peripheral schwannoma with broad pial adhesions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st2\">\n                    <jats:title>Case Description:<\/jats:title>\n                    <jats:p>A 60-year-old male presented with severe paraparesis attributed to a dorsal thoracic T11 tumor. Chronic hemodialysis precluded performing a contrast magnetic resonance. Intraoperative ultrasonography showed a well-defined, multi-cystic, and dorsal lesion without intramedullary extension. After dural opening, the tumor was tightly adherent to the dorsal spinal cord\/pia. A staged internal decompression improved tumor mobility, allowing the tumor to be progressively dissected away from its broad-based pial adhesion\/vasculature. Finally, a clean cleavage plane between the tumor capsule and spinal cord confirmed that the tumor was an extramedullary, broad-based pial schwannoma that was totally resected without neurological sequelae.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"st3\">\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Peripheral spinal schwannomas may occasionally exhibit broad-based pial adhesions that mimic intramedullary (subpial) or combined intra\/extramedullary lesions.
