Findings on imaging.. Notes: (A) Plain X-ray images show the apophysis of the bone on the lateral side of the femoral diaphysis. (B) Magnetic resonance T2-weighted fat-suppressed image shows the high signal intensity at the diaphysis. (C) Bone scintigraphy reveals an accumulation in the right femoral diaphysis.

We detected a stress fracture-like lesion that formed an eminence distal to the lateral cortical bone of the right femoral diaphysis (Figure 1A). Magnetic resonance imaging revealed low T1 signal with a 2 cm width, abnormally high T2 signals, and short inversion time inversion recovery for the right femoral diaphysis (Figure 1B). Bone scintigraphy revealed an abnormal accumulation in the distal right femoral diaphysis (Figure 1C).
MMA resin-embedded V bone stain.. Notes: A slight double-labeling of tetracycline can be observed. The trabeculae were narrow, and both osteoblasts and osteoclasts were decreased.. Abbreviations: MMA, methyl methacrylate; V bone, villanueva bone.

The trabeculae were narrow, and the number of osteoblasts and osteoclasts had decreased (Figure 2).
