This case study highlights the innovative diagnostic utility of Super-Resolution Contrast-Enhanced Ultrasonography (SRCEUS) in visualizing micron-scale vascular alterations and detecting enterovesical fistulas noninvasively in patients with intestinal Behçet’s disease.
Case Report
A 29-year-old female had recurrent oral ulcers for 10 years and abdominal pain for 2 years. Enhanced computed tomography (CT) and enteroscopy could not rule out ileocecal lymphoma, leading to a laparoscopic exam of the right colon. Pathology showed chronic inflammation, vasculitis, but no malignancy, diagnosing intestinal Behçet’s disease. Six months earlier, she had recurrent abdominal pain, urinary discomfort, and a positive urine test, with normal endoscopy. Recurrence of the disease with possible bladder involvement was considered. Computed tomography scans showed thickened pelvic small intestinal wall, intestinal convergence, and adhesion to the bladder. Bowel adhesion to the bladder wall suspected an enterovesical fistula, though direct visualization was not found. Conventional ultrasound and contrast-enhanced ultrasonography (CEUS) had similar findings to CT (Figure 1A-C).
