OBJECTIVE. To report the imaging characteristics of odontogenic myxoma (OM) and compare the different imaging modalities
STUDY DESIGN. The radiological images of 33OMcases were retrospectively analyzed. The radiographs were severally examined
to describe the features of OM as seen on conventional radiographs (CRs), computed tomography (CT) scans, and magnetic
resonance images (MRIs).
RESULTS. MRI was effective in displaying the true extension and contents of OMs. CT scans demonstrated the extensions of
OMs, expansion, growth pattern, and rendered it possible to compare density of OM with that of surrounding muscles.
Assessment of CRs revealed great limitations about the diagnostic values and failed to display important features.
Conclusions. All 3 radiographic techniques, conventional radiography, CT, and magnetic resonance imaging (MRI), have inherent
advantages and disadvantages; however, all 3 should be routinely used in the diagnosis of OM. The results of CTand MRI can
accurately reveal margins of tumors and greatly aid in diagnosis.
