RESUMO
Os navicular bone is an accessory bone of the foot, which is mainly found on the medial side of the proximal navicular bone. Os navicular bone may be symptomatic and cause medial foot pain. We report a case of a 42-year-old athlete male having right foot pain diagnosed with os navicular syndrome on 99mTc-MDP bone scintigraphy SPECT/CT. We emphasize on the use of SPECT/CT in not only allocating the ossicle anatomically, but also for the purpose of evaluating an active source of pain in a region of multiple complex small bones.

Pseudodystrophy is a rare condition clinically resembling reflex sympathetic dystrophy. Distinction between both disorders is based on clinical features and bone scintigraphy. We report a case of 12-year-old girl presented with pain, swelling, and functional impairment of left foot after minor trauma. Clinical assessment revealed atrophy of left calf, cyanosis and coldness of left foot. Laboratory investigations were normal. X-ray and MRI of the foot were unremarkable. Bone scintigraphy showed hypoperfusion and diffusely reduced tracer uptake in the left lower leg and left foot. Diagnosis of pseudodystrophy was made on the basis of history, clinical examination, and bone scintigraphy findings.
