Neurilemmomas are benign tumors that arise from Schwann cells. They are rar
ely found on bone. We describe a neurilemmoma in a 45-year-old patient that
affected the distal metaphysis of the radius. Only 1 previous case has bee
n described in the literature. We discuss the clinical presentation, the ra
diographic aspect, particularly the magnetic resonance imaging characterist
ics, and the microscopic findings. (J Hand Surg 2000;25A:365-369. Copyright
