We report a case of a 21-year-old woman presenting with quadriplegia which was initially diagnosed with an epidural abscess in view of her MR scan and raised inflammatory marker levels. Histology revealed an epidural extra-osseous Ewing's sarcoma (EES). Epidural location of EES is a very rare
In 1977, a program of early, wide-field radiation therapy (RT) to the central nervous system and repeated lumbar intrathecal (IT) medications along with systemic chemotherapy was begun by the Intergroup Rhabdomyosarcoma Study (IRS) for patients younger than 21 years of age with cranial parameningeal
Two patients, aged 24 and 19 years, who had undifferentiated lymphoma, developed the acute onset of focal neurologic deficits 10 days after treatment with moderate-dose methotrexate (2.76 g/m2 by 42-hour intravenous infusion) and 12.5 mg of intrathecal methotrexate. Prior chemotherapy also included
C2 vertebral body (axis) lesions are often approached anteriorly combined with posterior stabilization of craniovertebral junction (CVJ). The anterior approach has its limitations. A posterolateral corridor is an alternative access to the C2 body lesions, and this alone may suffice in Seven patients with bone or soft tissue sarcomas but without metastatic CNS disease developed a chronic leukoencephalopathy after high-dose (8000-15,000 mg/m2) iv methotrexate (MTX) chemotherapy with leucovorin (LV) rescue. Approximately 12 MTX-LV treatments were administered over a 3-7 month
