Costilla cervical en el diagnóstico diferencial de una masa supraclavicular
Bibliographic record
Abstract
Cervical rib in the differential diagnosis of supraclavicular massLa costilla cervical consiste en una costilla supernumeraria que surge de la séptima vértebra cervical y termina libremente en el tejido del cuello o se articula con la primera costilla.Puede ser asintomática y diagnosticarse como hallazgo casual en una radiografía de tórax, o bien presentarse con dolor en la región supraclavicular o como complicación en forma de síndrome del desfiladero torácico.A menudo plantea diagnóstico diferencial con masas tumorales malignas, por sus características en la exploración.El manejo suele ser conservador y la intervención quirúrgica se reserva para casos muy sintomáticos o complicados.Presentamos un caso clínico de costilla cervical sintomática y su abordaje desde Atención Primaria.Cervical rib is a supernumerary rib arising from the seventh cervical vertebra and ends freely in the tissue of the neck or articulates with the first rib.It can be diagnosed as an asymptomatic incidental finding on a chest radiograph or presented with supraclavicular pain or complications as thoracic outlet syndrome.The differential diagnosis often poses malignant tumor masses, because of their characteristics in the physical exam.The management is often conservative reserving surgical intervention for highly symptomatic or complicated cases.We report a case of symptomatic cervical rib and its approach from Primary Care.

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.
