AbstractSTUDY DESIGN.: Case report and literature review. OBJECTIVES.: To report the very rare case of a mature intramedullary teratoma with exophytic extension localized to the uppermost cervical spinal level in a 65-year-old woman and review the pertinent medical literature. SUMMARY OF BACKGROUND DATA.: Cervical intramedullary teratomas are extremely rare in adults, especially in patients older than 50 years. METHODS.: The patient presented with progressive ataxia, mild bilateral kinetic hand tremors, and dizziness. Magnetic resonance imaging revealed an intramedullary 1.7 x 1.3 x 2.3 cm mass at C1 with exophytic extension. A C1-C2 laminectomy and a partial suboccipital craniotomy were performed, followed by a subtotal microscopic resection of the tumor. Pathology was consistent with a mature teratoma. RESULTS.: After surgery, the patient's ataxia, tremor, and dizziness resolved almost immediately. CONCLUSION.: This report presents the very rare case of a mature intramedullary teratoma located in the upper cervical spine of an elderly patient, possibly the oldest patient documented with this type of lesion. The authors recommend a conservative subtotal surgical resection of cervical intramedullary tumors because it may improve symptoms that relate to direct mechanical cord compression and avoid further harm from a gross resection.
