Thoracic magnetic resonance imaging reveals an intramedullary long spinal cord lesion from T3 to lower levels at 1 day after admission. (a) Sagittal T2-weighted image. (b) Gadolinium enhancement of the lesion at T10-T11. (c) Axial T2-weighted image at T10, revealing a high-intensity signal in the center of the spinal cord.

An intramedullary spinal cord tumor was detected at T10-T11 that was enhanced by gadolinium (Figure 1).
(a-c) Histopathology of the surgically resected spinal cord tumor, revealing a high nuclear/cytoplasmic ratio with necrosis. The sections were stained by hematoxylin and eosin (H&E) (a) following immunostaining with synaptophysin (b) and CD56 antibodies (c). Both synaptophysin- and CD56-positive cells were observed. The tumor was attributed to small-cell lung carcinoma metastasis. Original magnification x100.
