<i>Escherichia coli</i>0157 enterohaemorrhagic colitis associated with pyelonephritis: CT findings
Bibliographic record
Abstract
Escherichia coli 0157:H7 is increasingly being recognized as a cause of infectious colitis, which typically results in bloody diarrhoea in an afebrile patient. The absence of fever often means that an infectious process is not considered in the differential diagnosis, particularly as this organism will not be detected in routine stool cultures. Inappropriate antibiotic therapy may increase the risk of development of haemolytic uraemic syndrome, a potentially fatal complication of this form of colitis, hence the importance of accurate diagnosis. On CT, it is characterized by severe diffuse colonic wall thickening, with little or no pericolic inflammatory changes. The radiologist may be the first to suspect the correct diagnosis and so should be aware of its imaging appearances. We report the case of a 19-year-old man who presented with typical radiological findings of enterohaemorrhagic colitis and whose CT also showed evidence of acute pyelonephritis; we suggest that this combination of abnormalities should further heighten radiologists' suspicions of infection due to E. coli 0157:H7, despite the absence of fever.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
