When she came to our hospital in November 1996, an ambulatory tumor was palpable at the carpal tunnel. She had sensory disturbance and numbness in the median nerve area. The distal motor latency was 5.1 msec. Roentgenogram did not show tumor. In magnetic resonance imaging (MRI), tumor showed high intensity in T2 image. In December 1996 surgery was performed.
