Abstract
AbstractMagnetic resonance imaging of spinal dural arteriovenous fistula (SDAVF) shows longitudinally extensive spinal cord lesions mimicking neoplastic or inflammatory myelopathy. On positron emission tomography/computed tomography (PET/CT), we report two patients who showed focal 18F‐fluorodeoxyglucose (FDG) uptake in longitudinally extensive spinal cord lesions. These lesions were indistinguishable from tumors or myelitis but were finally diagnosed as SDAVF. Although PET/CT availability may be limited, in cases of myelopathy with diagnostic challenges, it is important to recognize that focal FDG uptake can be observed in SDAVF.
