How a Seemingly Minimal Physical Exam Finding Unveiled a More Serious Condition: A Case Report
Bibliographic record
Abstract
Cerebral contusion following a concussion is a severely debilitating and possibly life-threatening condition that is not readily uncovered in American football players. We describe the case of a 16-year-old high school male who presented to a university-based concussion clinic 5 days post helmet-to-helmet collision with symptoms of nighttime headaches, dizziness, and difficulties with concentration and word finding. Neurocognitive evaluation demonstrated decreased visual and verbal memory, along with a very high concussion symptom score on the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT ® ). Physical examination findings revealed lower extremity hyperreflexia with pathologic spread to bilateral knees and Achilles tendons. These focal neurologic signs prompted obtention of brain and cervical spine imaging, which demonstrated a right temporal lobe contusion and multiple cervical disc herniations. This case emphasizes the importance of a thorough neurologic examination. Failure to recognize these critical signs could have resulted in premature or unsafe return to play, ultimately exposing the athlete to the risk of additional trauma. Concussion is primarily diagnosed clinically and therefore imaging is not routinely obtained. Thus, fastidious upper motor neuron testing should be a fundamental component of the standard neurologic examination when evaluating players suspected of having a concussion.

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.
