Inflammatory Myofibroblastic Tumors in Paranasal Sinus and Nasopharynx: A Clinical Retrospective Study of 13 Cases

Figure 1

A 33-year-old woman complained of facial swelling, diplopia, and impaired vision. CT and MRI showed a soft-tissue tumor in the right maxillary sinus and orbit. Six years ago, she had been diagnosed with plasma granuloma of the right middle ear. This time she was diagnosed with an inflammatory myofibroblastic tumor and underwent endoscopy-guided incomplete resection, combined with prednisone and chemotherapy. After 1-year follow-up, her symptoms were significantly relieved. T2-weighted (a) and CT (c) coronal images showed a hyperintense and isodense mass in the maxillary sinus and orbit. Axial contrast-enhanced T1-weighted image (b) and CT (d) showed the intense enhancement of the soft-tissue tumor.
