Repeated Meningitis as a Delayed Complication of Scoliosis Surgery
Bibliographic record
Abstract
STUDY DESIGN: Case report. OBJECTIVE: To report a case of very delayed repeated meningitis after surgical treatment of scoliosis. SUMMARY OF BACKGROUND DATA: Delayed infection after spine surgery is a well-reported phenomenon, presenting usually with local wound symptoms and back pain. The occurrence of meningitis after spinal instrumentation is reported but not common. Delayed repeated episodes of meningitis after surgical treatment of scoliosis have never been reported. CASE REPORT: We report a case of a 44-year-old gentleman, submitted to surgical treatment of scoliosis years ago, who presented with repeated episodes of meningitis due to the formation of an abnormal communication between an infected cyst in the bone cavity where the rods were located and the intradural space in the lumbar spine. Computerized tomography and magnetic resonance imaging revealed the presence of a bone cyst with thickened layering, and surgical exploration revealed the communication between this cystic cavity and the intradural space. After surgical closure of the dural space and cleaning of the cyst, the patient responded well to antibiotic therapy and was free of new episodes of meningitis up to the last follow-up, 1 year after the surgical treatment. Clinical diagnosis of delayed postoperative infection in spine surgery may be difficult if no wound signs are present. Clinical symptoms vary and may include increased back pain, wound redness, swelling and drainage, elevated erythrocyte sedimentation rate and white blood count, fever, and malaise. CONCLUSIONS: Delayed meningitis can be a late complication of spinal instrumentation for scoliosis. A high index of suspicion is necessary.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
