Abstract:
Objective: To investigate spiral CT and MRI manifestations of jaw odontogenic myxoma (OM). Methods: Totally 40 patients with OM confirmed by pathology were collected, and their CT and MRI manifestations were retrospectively analyzed. Results: The mean age of onset was (33.5±13.5) years. The lesions located in maxilla in 11 patients, while in mandible in 29 patients. CT showed expansive bone destruction in all 40 cases and cortical destruction in 8 cases. Most lesions were multilocular with vertical or angular septations oriented toward the periphery of tumor. The edge of lesions strengthened on enhanced CT. Adjacent teeth exfoliation was observed in 18 cases. Among 5 patients underwent MRI, 3 showed homogeneous equisignal on T1WI and 2 showed homogeneous slightly higher signal. T2WI presented high signal and interior low signal line-like separation. The edge of lesions strengthened on enhanced MRI in 2 cases. Conclusion: CT manifestations of jaw OM are of characteristics, which combining with MRI is of great significance in diagnosis of jaw OM.
