title: Primary dumbbell-shaped epidural myxoid liposarcoma of the thoracic spine: A case report and review of the literature.
abstract: Myxoid liposarcoma frequently occurs in the deep soft tissue of the extremities, particularly in the thigh. The present study describes an extremely rare case of primary dumbbell-shaped epidural myxoid liposarcoma of the thoracic spine occurring in a 22-year-old woman. Although preoperative magnetic resonance imaging findings were thought to be compatible with schwannoma, the pathological diagnosis of the resected tumor was myxoid liposarcoma. The patient underwent three courses of adjuvant chemotherapy with doxorubicin and ifosfamide, and exhibited no symptoms or signs of local recurrence or metastasis for 18 months post surgery. The present case suggests that, when radiologically diagnosing spinal epidural tumors, clinicians should consider the possibility of myxoid liposarcoma.
