The differentiation of a peritonsillar abscess from peritonsillar cellulitis, although difficult on physical examination, is required in order to determine the appropriate treatment. Peritonsillar cellulitis can be treated with antibiotics alone, while a peritonsillar abscess should be drained. Computed tomography (CT) of the neck is often performed to identify the formation of a deep abscess in the neck, but is rarely used to diagnose peritonsillar infections. We report a patient in whom CT was a useful diagnostic tool for distinguishing peritonsillar abscess from peritonsillar cellulitis.

The sagittal plane, computerized tomography (CT) scan has been proposed as the most important radiological view in the diagnosis of orbital floor blow-out fractures. This view however is impractical and unnecessary. Direct, coronal plane CT scan with careful attention paid to the shape of the inferior rectus muscle and antral roof will successfully diagnose this traumatic condition, as in our reported case in which no other radiological abnormalities were present.
