We present a case of intraosseous neurilemmoma of the fibula in a 56-year-old woman. The case showed the typical radiographic appearance except for the presence of spotted calcifications that mimicked a cartilaginous tumor. Enhanced MR images revealed the heterogeneity of the tumor, which consisted of Antoni type A and B tissue.

Discontinuous MVFs generally caused by mild outer force, and often occurred at the thoracolumbar junction. Continuous MVFs, frequently, were caused by high-energy trauma.
