99mTc methylene diphosphonate (MDP) planar scintigraphy images of the patient. Flow (a) and pool (b) Anterior; (c) Posterior) images are unremarkable. On delayed images, mild focal uptake noted in the region of great toe (arrow) [R: Right]

Flow [Figure 1a] and pool images [Figures 1b and c] of the feet were unremarkable. Delayed planar imaging acquired three hours after radiotracer injection showed a faint focal area of tracer uptake in the region of the right great toe [Figure 1d].
Single photon emission tomography-computed tomography (SPECT-CT) images of feet. CT images (a) do not show any abnormality of right lateral sesamoid (arrow). SPECT (b) and SPECT-CT (c) images show focal uptake of radiotracer in right lateral sesamoid (arrow) [R: Right]

CT images were unremarkable [Figure 2a]. SPECT [Figure 2b] and SPECT-CT [Figure 2c] images showed focally increased radiotracer uptake in the lateral right sesamoid bone.
Volume-rendered 99mTc methylene diphosphonate (MDP) single photon emission tomography-computed tomography (SPECT-CT) images of right foot. The volume of focal uptake of SPECT (arrow) is superimposed on the volume-rendered CT images. Characteristic pattern of uptake in the sesamoid bone is seen

Volume-rendered SPECT-CT image [Figure 3] showed the radiotracer uptake in the right lateral sesamoid bone.
