Diagnostic importance of Bone scan and SPECT-CT in atypical cases of CRPS presenting to pain clinic: A case report

Abstract

Establishing a diagnosis of complex regional pain syndrome (CRPS) is challenging and often requires a multidisciplinary approach. Skeletal scintigraphy (bone scan) can be helpful in diagnosing and staging CRPS. Presented here is an interesting case of the right upper extremity and pectoral region pain, which upon evaluation with skeletal scintigraphy and single photon emission computed tomography with computed tomography (SPECT-CT) turned out to be Pancoast tumor.
