What could white spots on lower spine mean?

White spots on the lower spine, visible on imaging studies like X-rays or MRI, could indicate several conditions, including bone lesions, infections, or degenerative changes. They may represent areas of decreased bone density, such as osteoporosis, or could signal the presence of tumors or metastatic disease. It's essential to consult a healthcare professional for proper evaluation and diagnosis based on clinical symptoms and imaging findings.
