  • Look Inside

With CT of the paranasal sinusitis mucosal swell-ing can not be distinguished from fluid accumula-tion within the sinuses in patients with chronic sinusitis. We studied 12 cases of chronic sinusitis (17 sides) by means of CT and MRI, with which we could distinguish mucosal swelling from fluid accu-mulation in the maxillary sinuses.

It was found that in a majority of cases with total clouding of the maxillary sinus the degree of swell-ing of mucous membrane was relatively small. This indicates that the main cause of total clouding of the maxillary sinus found in CT is due to accumula-tion of fluid rather than from obliteration of the sinus due to swelling of mucous membrane within the maxillary sinus.
