lüll Spinal Metastasis Ziu E; Viswanathan VK; Mesfin FBStatPearls-/-ä 2024[Jan]; ä (ä): äSpinal metastases are the most common tumors of the spine, comprising approximately 90% of masses encountered with spinal imaging. Spinal metastases are more commonly found as bone metastasis, although they are not limited to bone metastasis, and approximately 20% present with symptoms of spinal canal invasion and cord compression. Within the spinal column, metastasis is more commonly found in the thoracic region, followed by the lumbar region, while the cervical region is the least likely place professionals find metastasis . While evaluating spinal metastasis on MRI imaging, a defining feature of these lesions is the sparing of intervertebral disc space. This disc space is almost always involved during infection. Metastatic diseases to the spine spread through several different routes which include venous hematogenous spread versus the arterial spread, direct tumor extension, and lastly lymphatic spread. Among the routes mentioned above, hematogenous spread through Batson's plexus system is the most common pathway for tumor embolization and spinal invasion. The following summary emphasizes the essential knowledge necessary to have while treating patients with spinal metastasis .ä |
