Epidermoid Intramedullary Cyst: A Rare Case Report
Bibliographic record
Abstract
Epidermoid cysts are tumors that ocur in most parts of the body and are often treated by neurosurgeons, but intramedullary localizations of epidermoid cysts are very rare. The incidence in adults is lower than 1% and in children lower than 3%.We report a case of a 27-year-old patient presenting with thoracic spinal cord compression syndrome (T11-12). The magnetic resonance imaging (MRI) showed an intramedullary cystic mass. It demonstrated low signal intensity on T1-weighted sequence and high signal intensity on T2-weighted sequences, with minimal peripheral enhancement following intravenous administration of gadoteric acid. After surgical removal of the tumor, the pathology confirmed the radiological diagnosis of spinal epidermoid cyst. MRI reduces the delay in diagnosis of spinal cord tumors but should be guided by clinical judgment. J Med Cases. 2019;10(3):67-71 doi: https://doi.org/10.14740/jmc3224

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.
