This report is of a patient with foramen magnum papillary meningioma. The condition is rare and this report highlights its unusual 10-year clinical course. Angiographic features underestimated the extreme vascularity at the initial surgery when the diagnosis was made. Subsequently, multiple debulking and decompression procedures were performed to prevent cord compression. Multiple lesions with similar histopathological features developed in the thoracic and lumbosacral spine and a recurrence occurred at the skull base.
