Case report highlights trans-fistula contrast-enhanced ultrasound's value in diagnosing fistula features, suggesting improved assessment methods for Crohn's disease.
This case report presents an uncommon presentation of Crohn's disease (CD) complicated by an anal–Bartholin–perineal fistula. Notably, ultrasound was the initial imaging modality to demonstrate suspicious fistulous tract features in this case. Definitively, trans‐fistula contrast‐enhanced ultrasound (TF‐CEUS) clearly visualized the fistula, providing real‐time dynamic architectural details that were critical for diagnosis. TF‐CEUS emerged as a valuable diagnostic adjunct in this case, offering novel insights into evaluating complex perianal fistulous disorders in CD, particularly when conventional imaging modalities like MRI yield inconclusive results.
