Viborg's Triangle is an anatomical landmark used for safe entry into which space?

• A. Retromandibular space
• B. Inguinal canal
• C. Pleural cavity
• D. Cranial fossa

Answer: (C)

The main idea is safely accessing a specific body space using an established anatomical landmark. Viborg's triangle is a small triangular region in the lower neck that overlies the apex (cupula) of the pleural cavity. By entering through this area, a clinician can reach the pleural space for procedures such as drainage or thoracostomy while avoiding deeper structures and major vessels that lie more medially or posteriorly. This makes it a useful reference for accessing the pleural cavity rather than spaces like the retromandibular region behind the jaw, the inguinal canal, or the cranial fossa.
