Which of the following is true about strangles in relation to Viborg's Triangle?

• A. Viborg's Triangle swells during strangles
• B. Viborg's Triangle prevents swelling
• C. Strangles are unrelated to Viborg's Triangle
• D. Strangles causes atrophy of Viborg's Triangle

Answer: (A)

Strangles causes enlargement of the head and neck lymph nodes, especially the submandibular and retropharyngeal nodes. Viborg's triangle is the ventral neck region where these deep nodes are palpated clinically. When these nodes become inflamed and form abscesses, the overlying tissues bulge, making Viborg's triangle visibly or palpably swollen. This swelling in that region is a hallmark of strangles and reflects the infection spreading to those lymph nodes. The other ideas don’t fit because the condition doesn’t prevent swelling, isn’t unrelated to that region, and doesn’t cause atrophy of Viborg's triangle.
