The clinical sign that is considered pathognomonic for aspiration pneumonia is abnormal lung sounds.

Here's a step-by-step explanation:

1. Aspiration pneumonia is a type of lung infection that is due to a relatively large amount of material from the stomach or mouth entering the lungs.

2. Signs and symptoms often include fever and cough of relatively rapid onset.

3. Complications may include lung abscess.

4. The key clinical sign that is considered pathognomonic (specifically indicative) for aspiration pneumonia is abnormal lung sounds, such as crackles, wheezes or decreased breath sounds.

5. These abnormal lung sounds are typically detected through a physical examination with a stethoscope.

6. Other symptoms like depression, nasal discharge, dysphagia, or sudden death after drenching are not specific to aspiration pneumonia and can be seen in many other diseases.

7. Therefore, abnormal lung sounds are considered the pathognomonic clinical sign for aspiration pneumonia.
