title: PET/CT imaging of conus medullaris metastasis from lung cancer.
abstract: An intradural extramedullary metastasis is usually detected at an advanced stage of the disease or during workup for manifestations of spinal cord compression. Early diagnosis of such a lesion is rare and mostly fortuitous. The authors present a case of treated nonsmall cell lung carcinoma with an asymptomatic conus medullaris metastasis, which was demonstrated by PET/CT imaging during restaging evaluation.
