Question

Prevertebral soft tissues (PLT)

1) landmarks

2) if positive it is indicative of _____

3) Retropharyngeal (C2-4) > _____

4) Retrolaryngeal (C5) > _____

5) Retrotracheal (C6-7) > ______

Answer 1

The prevertebral soft tissues (PLT) are anatomical structures in front of the vertebral column. They include landmarks like the thyroid cartilage and thyroid gland. If they appear positive on imaging, it can indicate certain conditions. The retropharyngeal, retrolaryngeal, and retrotracheal spaces are specific regions where these soft tissues can be seen.

Step-by-step explanation:

The prevertebral soft tissues (PLT) refer to the anatomical structures located in front of the vertebral column. They include the following landmarks:

1. Thyroid cartilage of the larynx
2. Thyroid gland
3. Parathyroid glands (on posterior side of thyroid)
4. Trachea

If the prevertebral soft tissues appear positive on imaging, it can be indicative of various conditions such as infections or tumors. The retropharyngeal space (C2-4), retrolaryngeal space (C5), and retrotracheal space (C6-7) are specific regions in the neck where these soft tissues can be visualized.
