Pak J Med Sci Jan ;27(1):214-5.

The incidence of parapharyngeal abscess has reduced dramatically, with the evolution of antibiotics. In a high risk patient for example diabetics, the condition do occur and the abscess is usually well formed and frank abscess will be drained. We report a case of diabetic lady who presented with left neck mass. Imaging showed collection of pus with trapped air under the fascia. Culture from drainage obtained revealed Klebsiella pneumonia, which is a rare organism in the region.
