Incidentally Found Soft Tissue 99mTc-DPD Uptake on Bone Scintigraphy Was Useful in an Early Diagnosis of Peripheral Arterial Disease.

Peripheral arterial disease (PAD) is a critical disease which is presented by occlusion of peripheral arteries, while it could result in amputation of the involved limbs if it remained untreated before it would progress into tissue necrosis. It is usually diagnosed by CT angiography or conventional angiography, but its early diagnosis is challenging because its symptoms may be absent or like those of other diseases. In this case report, the authors showed that an atypical soft tissue uptake of lower limb incidentally found on a bone scintigraphy resulted in early diagnosis and successful treatment outcome of PAD.
