Special Sono-Case: Targeted high-frequency ultrasound mapping of a draining cutaneous tract, including its course, depth, vascularity, and relationship to deeper structures.

Why this case matters

A small skin opening may conceal a complex inflammatory tract, abscess, foreign body reaction, or postoperative communication. Dynamic scanning and careful tract mapping can guide management.

The case covers

• High-frequency scanning and stand-off technique
• Tract measurements, compressibility, debris, and hyperemia
• Search for abscess, foreign body, and deep communication
• Reporting language, pitfalls, and ARDMS-style questions
