Spontaneous Resolution of Calvarial Eosinophilic Granuloma in Children
Bibliographic record
Abstract
OBJECTIVE: The recommended treatment for solitary calvarial eosinophilic granuloma (EG) is surgical resection by curettage, craniectomy or craniotomy. The purpose of this study was to describe the spontaneous resolution of calvarial EG and discuss 'observation only' as an option in the management of this condition. METHODS: A retrospective review was performed of children with calvarial EG seen at a tertiary care children's hospital. Of a total of 17 such patients, four were managed without any intervention and formed the basis of this report. RESULTS: In all four patients treated by 'observation only', there was a tender calvarial mass which enlarged rapidly over a few days and then resolved slowly over many weeks. The diagnosis of EG was based on the findings of plain radiographs and/or computed tomography. All masses had resolved by 8 weeks, and the underlying cranial defect filled in spontaneously in all cases. There was no recurrence at follow-up, which ranged from 2 months to 7 years. CONCLUSIONS: 'Observation only' should be considered as a viable option in the management of children with solitary calvarial masses that have the radiographic features of EG. Consideration should be given to delaying surgical intervention to allow time to see if spontaneous resolution occurs.

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.
