Rare appendicular anomaly of horseshoe appendix diagnosed intra-operatively during laparoscopic appendectomy: case report
Bibliographic record
Abstract
Acute appendicitis is the most common cause of lower abdominal pain among patients presented to the Emergency Department. Appendicular anomalies in general are rare, and the horseshoe appendix is considered the rarest, with few reported cases in the literature. We are presenting a young female patient, medically and surgically free, who presented to the Emergency Department with persistent right lower quadrant, associated with vomiting for 2 days. Vitally was stable, and labs were remarkable for leukocytosis and neutrophil shift. Abdomen CT scan showed a dilated appendix up to 1 cm with mural edema and hyperenhancement surrounded by mild fat stranding, minimal free fluid, and thickened adjacent peritoneal reflection. In conclusion, routinely performed surgeries can surprise the surgeon with unusual findings. Knowing the anatomy and possible associated anomalies is a cornerstone for any surgery. Even with the rarity of these anomalies, a high index of suspicion and careful recognition are required.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
