RADIOLOGY: NECK: Case# 33041: PARAPHARYNGEAL ABSCESS. This is a 23 year old male with a history of tonsillitis. There is marked bilateral parapharyngeal space swelling and inflammation, beginning at the level of the pharyngeal tonsils and extending downward to the upper most level of the epiglottis. Within the right parapharyngeal space, there is a fluid density area measuring approximately 1.0 x 1.5 cm in transverse dimensions . A low density focus in the left parapharyngeal space suggests some necrosis in this location also. The degree of parapharyngeal swelling largely obliterates the lumen of the oropharynx.
