A 12-year-old boy experienced worsening lumbar pain and limited movement in his lower spine, but initial X-rays did not show any issues.
A CT scan later revealed structural changes in the L3 vertebra and a paravertebral abscess, leading to the diagnosis of spondylitis linked to a coagulation-negative Staphylococcus aureus infection.
Following surgery, antibiotic therapy was adjusted due to antibiotic resistance, and after 15 weeks, the patient showed significant improvement with a full range of motion and no complaints, highlighting the importance of timely diagnosis and treatment in children.
