[MRI of the paranasal sinus mucopyocele].

ABSTRACT

Seven cases of the paranasal sinus mucopyocele were examined by MRI. All of the mucopyocele in our series were clearly demonstrated on MRI using long SE pulse sequence as high signal intensity. However, the degree of signal intensity was varied based on the contents of the mucopyocele. We can detect the mucopyocele as a three dimensional image by MRI, however, CT was necessary for evaluating the bone destruction caused by mucopyocele.
