Herniation of a Calcified Cervical Disc Into the Foramen Transversarium in an 8-Year-Old Child
Bibliographic record
Abstract
STUDY DESIGN: Herniation of a calcified C3-C4 disc into the left foramen transversarium in a child is reported. OBJECTIVE: To discuss the natural history and management of a calcified disc herniation into the foramen transversarium. SUMMARY OF BACKGROUND DATA: Cervical disc calcification in children usually follows a benign course. Herniation of the calcified disc into the spinal canal has already been described. However, herniation into the foramen transversarium has never been reported. METHODS: An 8-year-old girl presented with progressive neck pain and torticollis. Her neurologic examination was normal. She was treated using a head halter traction, analgesics, and muscle relaxants for 3 days, followed by the use of a soft cervical collar for 2 weeks. RESULTS: Computed tomography scan showed a calcified C3-C4 disc with herniation into the C3 left foramen transversarium. Her symptoms subsided and she rapidly regained full range of motion of her neck after 3 days of conservative treatment. Magnetic resonance angiography done after 2 months did not show any residual compression of the left vertebral artery. After 3 months, the herniation had completely disappeared, whereas only a small central calcification remained in the C3-C4 disc space. CONCLUSION: The natural history of cervical disc calcification is usually benign. A computed tomography scan can be performed for patients in whom a calcified disc herniation is suspected on the plain films. In this case of herniation into the foramen transversarium, magnetic resonance angiography was useful to evaluate the integrity of the vertebral arteries. Spontaneous resolution of the herniated disc and return to normal function can be expected with conservative treatment.

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.
