Primary polymorphous hemangioendothelioma of the spinal cord. Case report.
A case of polymorphous hemangioendothelioma of the spinal cord is described. This 55-year-old woman presented with an 18-month history of lower-extremity sensorimotor deficit. A magnetic resonance image revealed an enhancing, intradural, extramedullary nodule at the T 1-2 level. On gross inspection, the lesion measured 3.5 cm and was firmly attached to spinal cord parenchyma and adjacent nerve roots. It was completely removed. Fourteen months after surgery the patient's neurological deficit had resolved. Polymorphous hemangioendothelioma is a rare vascular tumor of borderline malignancy. Most occur in lymph nodes. None has been reported to occur in the central and peripheral nervous system. Based on current experience, resection and close follow up seems the best therapeutic approach.
