[Intramedullary spinal cord metastasis presenting with acute onset longitudinally extensive spinal cord lesion].
A 34-year-old previously healthy man presented with acute transverse lumbar myelopathy and MRI evidence of a longitudinally extensive spinal cord lesion (LESCL) from the upper thoracic cord extending down to the conus medullaris. Gadolinium-DTPA enhancement revealed a clearly demarcated enhanced nodule confined to the level of the 11th thoracic vertebral body (T11), which might have caused longitudinally extensive edema in the spinal cord. Histopathological appearance of adenocarcinoma of the nodule led to the ultimate diagnosis of lung cancer. Intramedullary spinal cord metastasis in a young patient without previously-diagnosed malignancy is a rare disorder, but should be listed up as a cause of LESCL.
