Axial T2 ‐ weighted magnetic resonance image (repetition time, 3500 msec; echo time, 96 msec), made at the distal level of the leg, showing a fatty tumor with central signal voids (arrow). Akira Ogose et al. J Bone Joint Surg Am 2002;84: ©2002 by The Journal of Bone and Joint Surgery, Inc.
Operative photograph showing the exposed fibrofatty tumor intermixed with the swollen superficial peroneal nerve (arrow). Akira Ogose et al. J Bone Joint Surg Am 2002;84: ©2002 by The Journal of Bone and Joint Surgery, Inc.
Low-power micrograph of a histological section, made at almost the same level as Fig. 2-B, showing that the signal voids on magnetic resonance images correspond to the nerve fascicles and the perineural fibrosis (magnification, 5).
