Physical examination revealed bony hard swellings involving the whole of left thigh and anterior part of the left mid-shin (Figures 1A,B). Radiograph of the affected part showed a deformed left femur and left ischium with multiple expansile lytic areas (Figure 1C).
(A,B) Bone scintigraphy image, anterior view showing increased tracer uptake involving the left ischium, femur and part of tibia at baseline (A) and slightly reduced tracer uptake at the left femur when followed up at 6 months (B). (C,D) Bone scintigraphy image, posterior view showing increased tracer uptake involving the left ischium, femur, and part of tibia at baseline (C) and slightly reduced tracer uptake at the left femur when followed up at 6 months (D).

Bone scintigraphy showed increased tracer uptake involving the left ischium, femur and part of tibia (Figures 2A,C, anterior and posterior views, respectively). The anterior uptake values at left thigh and left tibia at baseline were 3.07 and 3.55, respectively (Figure 2A); at 6 months, the corresponding values were 2.43 and 3.60, respectively (Figure 2B). Similarly, the posterior uptake values at left thigh and left shin at baseline were 2.25 and 1.46, respectively (Figure 2C); the corresponding values at 6 months follow-up were 1.68 and 1.48, respectively (Figure 2D) (summarized in Table 1).
