Conclusion

Ultrasonography is an accurate, noninvasive and inexpensive tool that can play an important role in promptly diagnosing peritonsillar abscess which in turn is fundamental to adequately treat and improve the outcome.

Therefore, radiologists must be familiar with the normal sonographic anatomy of the palatine tonsils and the spectrum of peritonsillar infections that may manifest as peritonsillar swelling.

However, there are some clinical conditions in which performing computed tomography imaging may improve the reliability and accuracy in the final diagnosis.
