This case report describes the clinical presentation, imaging findings, and management of SSH in a 20-year-old female initially suspected to have urothelial malignancy. Imaging features of SSH include pre-contrast hyperdensity and non-enhancing thickening of the pelviureteric wall, which can mimic transitional cell carcinoma (TCC) and lead to unnecessary interventions. Radiologists should maintain a high level of suspicion for SSH and be aware of its imaging characteristics to avoid misdiagnosis. Additionally, clinical data, such as bleeding dyscrasia, can aid in the imaging diagnosis. This report provides insights into the diagnosis and management of SSH while offering a comprehensive literature review on its clinical presentation and imaging features. Increased awareness of SSH will facilitate accurate diagnosis and appropriate management, avoiding unnecessary interventions for patients with this benign condition.Keywords: Antopol-Goldman lesion, hematuria, INR, non-contrast enhanced CT, SSH, spontaneous suburothelial hemorrhage

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.
