• I have had left hip and leg pain for a year.
• The patient underwent two lumbar disc herniation surgeries abroad due to incorrect diagnoses.
• The patient's symptoms worsened over time, and he or she became unable to walk.
• A patient diagnosed with chondrosarcoma via needle biopsy showed no signs of metastasis in subsequent scans.
