Cervical meningioma masquerading as schwannoma: two cases and a review of the literature.

Two patients presenting with intradural, extramedullary, transforaminal ''dumbbell-shaped'' tumors are discussed. While imaging studies were strongly suggestive of schwannoma, both patients were diagnosed with meningioma. Presentation, imaging studies, operative intervention and pathology are described. Due to the difficulty in achieving complete resection, and the propensity for recurrence, long-term follow-up is recommended.
