Ewing sarcoma is a malignant tumour of the bone that sometimes presents extraskeletal involvement, with the epidural location being rare. We report the case of a 45-year-old woman with paresthesia, paresis and urinary retention. Magnetic resonance imaging showed an epidural mass from C6 to D3. Laminectomy from C7 to D2 and partial resection of the lesion was performed. Pathological analysis was consistent with Ewing sarcoma. The patient received chemotherapy and radiotherapy, without evidence of disease at 8 months follow-up. A review of the literature on all published cases of extraskeletal Ewing sarcoma with epidural involvement is presented.

Hemangioblastomas are low-grade, highly vascular tumors commonly associated with von Hippel-Lindau (VHL) syndrome and most often appearing in the cerebellum. They very rarely occur in the spinal nerve roots, and an origin in the filum terminale is exceptional with no instances of multiple hemangioblastomas of the filum terminale reported in the literature. Because of their vascular nature, these lesions can enlarge and become symptomatic in the context of the changes that take place during pregnancy, as has been noted with cerebellar hemangioblastomas. In any case, the evolution of spinal hemangioblastomas during pregnancy is not well known given its rarity. The conjunction of both processes--that is, multiple hemangioblastomas arising in the filum terminale and pregnancy--is unique. The authors describe the case of a 41-year-old woman with multiple hemangioblastomas of the filum terminale and no other evidence of VHL syndrome, in whom pregnancy precipitated symptoms. The interruption of gestation led to a remission of the symptoms. The literature concerning filum terminale hemangioblastomas and pregnancy is also reviewed.
