    Abstract:
    Oligodendroglioma of the spinal cord is a rare tumor that most often presents with spinal cord symptoms. The authors present a case of spinal cord oligodendroglioma that was associated with cerebral rather than spinal cord symptoms. A 30-year-old woman developed nausea, vomiting, and severe headaches. Magnetic resonance imaging of the brain showed meningeal enhancement. The patient underwent a craniotomy with biopsies of the meninges and brain. The biopsy findings revealed an abnormal arachnoid thickening without tumor cells. The patient later developed hydrocephalus and underwent shunt placement. Cerebrospinal fluid cytological findings were negative for tumor cells or infection. She was found to have a cervical cord lesion at C3-4 that was initially nonenhancing but later enhanced after Gd administration. Biopsy of the cord lesion with partial resection showed a WHO Grade II oligodendroglioma with 1p and 19q deletions determined by fluorescence in situ hybridization. Neurooncological treatment with tumor radiation and temozolomide (Temodor) resulted in improvement in radiographic findings, symptoms, and long-term survival. This paper presents an extensive review of the literature, which revealed only 2 other reported cases of cerebral symptoms in adults that preceded spinal cord symptoms in a patient with oligodendroglioma of the spinal cord. It is also the first reported case of oligodendrogliomatosis due to a cervical spinal cord oligodendroglioma with 1p and 19q deletions.
