Epithelioid hemangioma of the skull: Rare case report
Bibliographic record
Abstract
Introduction: Epithelioid hemangiomas (EH) are benign vascular tumors that commonly occur in the skin, subcutis, and bone—most typically arising as nodules in the neck and head region. Pediatric cases with atypical presentations remain rare and challenging. Case Report: The following outlines the case of a 2-year-old male who presented with a bump and swelling on the left side of his head. Imaging tests identified multiple, hyperdense, and focally ring-enhancing intra-axial lesions located mainly at the gray-white matter junction of bilateral frontal left-sided parietal, left-sided occipital, and left-sided temporal lobes. In addition, multiple lytic lesions were seen in the calvarium. Pathology confirmed EH. While one lesion required surgical resection, the remaining lesions showed spontaneous regression during follow-up. Conclusion: This case highlights the diagnostic and management challenges associated with pediatric EH involving the head, including intracranial involvement. The patient’s unique presentation, age, and lesion involution expand the understanding of EH beyond its typical manifestation.

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.
