Pelvic congenital arteriovenous malformation diagnosed by transrectal ultrasonography: A case report
Bibliographic record
Abstract
Arteriovenous malformations (AVMs) of the pelvis are relatively rare and difficult to treat because of multiple and extensive feeding vessels. We report the case of a 69-year-old male with pelvic congenital AVM that was detected during tests for dysuria. He visited our hospital complaining of voiding difficulty. Digital rectal examination revealed a pulsating mass that was palpable on the right side of the prostate. Transrectal ultrasonography showed multiple hypoechoic lesions adjacent to the prostate and colour Doppler ultrasonography revealed the flow regions corresponded to the hypoechoic lesions. Computed tomography demonstrated large-to-small tubular vessels adjacent to the prostate, while pelvic angiography showed many small feeder arteries extending mainly from the right internal iliac artery. He was diagnosed as having pelvic congenital AVM. Uroflowmetry revealed slight voiding difficulty without residual urine. The patient decided against treatment and requested we monitor his clinical course.

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.
