Viborg's Triangle swells during which diseases?

Viborg's Triangle swells during which diseases?

• A. Tetanus
• B. Rabies
• C. Parvovirus infection
• D. Strangles and other diseases

Answer: (D)

Viborg's triangle is the neck region where swelling from enlargement of the head and throat lymph nodes becomes visible. When diseases cause lymph node inflammation and abscesses in this area, such as strangles, the tissues in Viborg's triangle swell noticeably. Strangles (Streptococcus equi) is a classic cause because it infects the retropharyngeal and submandibular lymph nodes, leading to neck swelling that often involves this region. Other diseases that produce regional lymphadenopathy in the head/neck can also cause similar swelling, so the best answer is “Strangles and other diseases.” By contrast, tetanus and rabies produce systemic or neurological signs rather than focal neck lymph node swelling, and parvovirus infection typically causes gastrointestinal signs rather than localized neck swelling.
