Abstract
Objective To improve the ability in diagnosing the tumors involved the maxillary sinus region through exploring the imaging characteristics of three kinds of diseases. Methods The clinical features, CT, and MRI appearances of neurofibroma, adenoid cystic carcinoma, and ossifying fibroma involved the maxillary sinus were observed. The imaging similarities and differences were analyzed. Results Maxillary sinus adenoid cystic carcinoma showed unclear boundary and osteolytic bone destruction. MRI demonstrated heterogeneous signal on T1WI and T2WI, and heterogeneous enhancement. Neurofibroma at pterygopalatine fossa revealed clear boundary and compressive bony absorption in adjacent bone. MRI showed heterogeneous signal on T2WI, and heterogeneous enhancement. Ossifying fibroma showed clear boundary and expansile bony change with osseous shell. MRI revealed heterogeneous signal on T1WI and T2WI, and heterogeneous enhancement. Conclusions The bony change is the key point for differential diagnosing the tumors involved the maxillary sinus. The finial diagnosis relies on combining the clinical, CT, and MRI findings.关键词
