Acute Emphasematous Cholecystitis
Bibliographic record
Abstract
Emphysematous cholecystitis (EC) is an uncommon variant of acute cholecystitis and can be rapidly lethal . We report an extremely rare case of EC and we present the imaging features of this patient. An 80-year-old male presented with epigastric pain and fever. Abdominal computed tomography confirmed the presence of an air-liquid level in the gallbladder lumen, gas within the gallbladder and in its walls. Emergency open cholecystectomy revealed necrotic changes in the gallbladder. The pat ient’s postoperative course was uneventful. The mortality associated with non-emphysematous is 4% compared with 15% for EC due to the increased incidence of gallbladder wall gangrene and perforation. The pathophysiology of EC differs from that in acute calculous cholecystitis . D iagnosis is established when the CT scan reveals gas within the gallbladder or in its walls in the absence of an abnormal communication between the gastrointestinal tract and the biliary system. T he standard treatment is emergent cholecystectomy and antibiotic therapy . It could conclude that surgeons should be aware of the existence of this kind of atypical presentation of cholecystitis. EC is a rare condition in which the abdominal computed tomograph proves to be a most useful tool. It is important to differentiate this rare pathologic feature of the gall bladder from other cholecystitis as the treatment is surgical rather than medical.

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.
