Paresis Associated With Aconuresis Caused by Intervertebral Disc Calcification at C7-T1
Bibliographic record
Abstract
In Brief Study Design. Case report. Objective. To report a case of a 19-year-old boy with intervertebral disc calcification (IDC) at C7-T1, who presented with paresis and aconuresis. Surgical outcome was assessed. Summary of Background Data. IDC, commonly seen in the cervical spine region in children, is well-known as a self-limiting disorder with no or little symptoms. Surgical intervention is usually not required. Methods. A 19-year-old boy presented with acute back pain, progressive numbness, and weakness of both lower extremities and aconuresis for 1 week. There was no traumatic history or signs of infection. Radiograph, computed tomography with reconstruction, and magnetic resonance imaging revealed C7-T1 IDC with severe spinal cord compression. Decompression with anterior cervical corpectomy and fusion was performed. Results. Follow-up showed complete resolution of the back pain and complete recovery of motor power and sensory function in both lower extremities and return of normal micturition function. The patient had full recovery with no complications. Conclusion. Serious neurologic deficit, especially a bladder dysfunction, caused by calcified intervertebral disc is rare. However, favorable outcome can be achieved in those cases where rapid diagnosis is made and followed by spinal cord decompression. Intervertebral disc calcification, commonly seen in the cervical spine region in children, is well-known as a self-limiting disorder with no or little symptoms. Surgical management is usually not required. The author reported the first case that surgical intervention is required of this condition at C7-T1.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
