Magnetic resonance imaging is useful fr diagnosing bone and soft tissue tumors. We report a patient with a schwannoma which gradually grew into a huge mass over a 12 year period. The deagnosis was possible using CT imaging, MRI, amgiogrephy, scintigraphy, and biospy. We recommend that MRI (especially, Gd-enhanced MRI) is useful for detecting the solid area of a huge systic mass for biopsy.
