Preoperative magnetic resonance imaging. The intramedullary lesion showing relative hyperintensity on T1-weighted magnetic resonance images (a) and hypointensity on T2-weighted magnetic resonance images accompanying the long-axis syringomyelia (b and c). The mass lesion showed homogenous contrast enhancement on T1-weighted images (d)

T1-weighted images [Figure 1a] and hypointensity on T2-weighted images, along with long-axis syringomyelia [Figure 1b and c]. The mass lesion showed homogenous contrast enhancement on T1-weighted images [Figure 1d].
Intraoperative photographs. Operative exposure showing extensive swelling of the spinal cord itself (a). Myelotomy via a dorsal midline approach showed presence of a grayish-red tumor (b). Gross total resection was successfully performed in a piecemeal fashion (c). Pathological diagnosis after surgery suggested poorly differentiated adenocarcinoma secondary to gastric cancer (H and E, x400) (d)

Operative exposure revealed extensive swelling of the spinal cord itself [Figure 2a]. Myelotomy via a dorsal midline approach revealed a grayish-red tumor [Figure 2b]. Gross total resection was successfully performed in a piecemeal fashion [Figure 2c]. Pathological diagnosis after surgery suggested poorly differentiated adenocarcinoma secondary to gastric cancer [Figure 2d].
Postoperative magnetic resonance imaging. Magnetic resonance images obtained 1 week after surgery showed no apparent lesion enhancement, with diminution of syringomyelia (a-c). Magnetic resonance images obtained 1.5 months after surgery showed local recurrence of the intramedullary tumor (d and e)

MRI obtained 1 week after surgery demonstrated no apparent lesion enhancement, with diminution of syringomyelia [Figure 3a-c]. MRI performed 1.5 months after the primary surgery demonstrated local recurrence of the intramedullary tumor [Figure 3d and e].
