Which of the following is NOT true about acute retropharyngeal abscess –
**Core Concept**
Acute retropharyngeal abscess is a collection of pus in the retropharyngeal space, which is a potential space in the neck between the buccopharyngeal fascia and the prevertebral fascia. This condition often occurs in children and is typically caused by a bacterial infection.
**Why the Correct Answer is Right**
The correct answer is related to the typical presentation and management of acute retropharyngeal abscess. This condition often presents with symptoms such as neck swelling, fever, and difficulty swallowing. Imaging studies, such as CT scans, are used to confirm the diagnosis. Treatment typically involves antibiotics and drainage of the abscess, either through needle aspiration or surgical incision and drainage.
**Why Each Wrong Option is Incorrect**
* **Option A:** Acute retropharyngeal abscess is a true statement about this condition. It is a medical emergency that requires prompt treatment.
