Abstract

Objective To evaluate the image features of low-grade myofibroblastic sarcoma(LGMS) of paranasal sinus, and improve the diagnostic accuracy. Materials and Methods A retrospective analysis of 5 cases of paranasal sinus LGMS was carried out. Of the 5 patients, all of them underwent common CT, 1 patient underwent contrastenhanced CT and 4 underwent common MRI and contrast-enhanced MRI. Results Of the 5 patients, 2 occurred in the right maxillary sinus and ethmoidal sinus, 2 occurred in the sphenoid sinus and ethmoidal sinus, 1 occurred in all of the left paranasal sinus. CT scan showed hypo-indense and iso-indense soft tissue mass in the paranasal sinus. T1WI showed isointense mass and T2WI showed isointense and hyperintense mass. Contrast images showed moderate-obvious homogeneous enhancement. All of the 5 cases showed bone destruction. Conclusion LGMS of the paranasal sinus can be characterized as a soft tissue mass with bone destruction, but it is difficult to differentiate from other malignant diseases. Image features can help to determine the extent of the lesion.
