“…Dürr et al (2001) described excision of a pseudotumor of the fifth metatarsal in a fifty-six-year-old woman 5 . Abu Hassan reported a 4-cm-long toothpick completely embedded in bone within the metatarsal head of a young female that was initially suspected of being an osseous tumor 6 . A preoperative MRI identified the toothpick within the bone prior to it being surgically removed.…”

“…More commonly, a penetrating foreign body in the foot, particularly a wooden object, can lead to cellulitis, osteomyelitis, or an apparent ''pseudotumor.'' [4][5][6][7][8][9] However, foreign bodies in the foot do not appear to migrate far, in contrast to those in the upper extremity, which can migrate along some distance [10][11][12] . We report a case of a toothpick penetrating a child's foot and migrating a sufficient distance to be undetectable with conventional imaging techniques.…”

A 23-year-old man referred by his primary care physician presented with a 1.5-year history of progressive left ankle pain and swelling. He recalled no history of trauma other than stepping on a horseshoe crab when he was 8 years old and having the tail removed in a local emergency department. He denied recent fevers, chills, night sweats, weight loss, or weight gain. Physical examination revealed substantial nonpitting edema around the hindfoot region extending up the distal 1 .3 of his leg. There was no skin discoloration. He had mild tenderness to palpation along the peroneal and posterior tibial tendons. There was normal strength and sensation in the foot and leg. No lymphadenopathy was noted. His laboratory values, including complete blood count, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), uric acid, rheumatoid factor, and Lyme titer were all within normal limits. Imaging studies, including MRI (Fig. 1), CT scan (Fig. 2), and bone scan (Fig. 3), were performed. Based on the history, physical examination, laboratory tests, and imaging studies, what is the differential diagnosis? Imaging InterpretationSagittal T1-weighted (Fig. 1A), sagittal T2-weighted fat-suppressed (Fig. 1B), and axial T1-weighted fatsuppressed contrast enhanced (Fig. 1C) MR images of the ankle showed a T1 hypointense and T2 hyperintense soft tissue mass remodeling the undersurface of the sustentaculum tali. There was a small irregular central area of low signal consistent with calcification.Coronal ( Fig. 2A) and sagittal (Fig. 2B) reformatted CT images of the ankle showed an area of smooth osseous remodeling at the inferior aspect of the sustentaculum tali. There was a 7-9 4-mm triangular calcification adjacent to the area of remodeling.Radionuclide bone scan (Fig. 3) of the bilateral feet and ankles showed radiotracer uptake in the left posterior calcaneus.Each author certifies that he or she has no commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article.

“…Most of the previously reported cases of foreign bodies retained in the foot bones occurred in the metatarsal bones (4,5), and a case of a wooden foreign body retained in the calcaneus has rarely been reported (6). The soft tissue in the forefoot and the midfoot is thinner and softer than that in the heel, and therefore, the foreign body can easily reach the bone.…”

“…As far as the English literatures are concerned, thorns, glass, needles or wooden fragments are the main foreign bodies that are retained in the foot or hand (3). Most of the foreign bodies are found in the metatarsal bones (4,5), and a wooden foreign body retained in the calcaneus has rarely been reported (6).…”
