Leptomeningeal carcinomatosis and intramedullary spinal cord metastases from lung cancer: detection with FDG positron emission tomography

Clin Nucl Med. 2001 Nov;26(11):905-7. doi: 10.1097/00003072-200111000-00001.


A 64-year-old man with a history of large-cell lung carcinoma and recent resection of a brain metastasis was examined because of a general decline in his ability to function. Whole-body positron emission tomography with fluorine-18 fluorodeoxyglucose (FDG PET) showed metastases along the spinal cord that were confirmed with MRI. Intramedullary spinal cord metastasis occurs rarely, and the prognosis is extremely poor. Whole-body FDG PET allows the entire spinal cord to be examined noninvasively compared with magnetic resonance imaging, computed tomography, and myelography.
