[Abstract] Objective: To study the MRI findings of adenoid cystic carcinoma (ACC) of the head and neck.Materials and Methods: All 20 cases of ACC were verified by histopathology. MRI data were analyzed retrospectively. Meantime, CT scanning were done in 15 cases.Results: The lesion mainly occurred in nasal cavity and paranasal sinus in 7 cases, in orbital 5 cases, in pterygopalatine fossa 3 cases, cranium, nasal and orbital were diffuse involved 2 cases, in root of tongue 2 cases, in external ear 1 case. The lesion involved two and more anatomic structures 15 cases, among them 9 cases involved pterygopalatine fossa, 9 cases involved maxillary nerve, 6 cases involved mandibular nerve, 8 cases involved nerve of pterygoid canal, 8 cases involved middle cranial fossa and cavernous sinus. On MR T1WI, the lesion showed isointensity in 13 cases and slightly hypointensity in 7 cases. On T2WI, the lesion showed isointensity in 13 cases, slightly or hyperintensity in 7 cases. All 20 cases showed heterogeneous intensity, showed short T1 and long or mixed T2 signal in 4 cases. Postcontrast MRI demonstrated obvious heterogeneous enhancement in 8 cases, moderate enhancement in 12 cases. Among 11 cases dynamic contrast MRI, dynamic contrast curve showed rapid ascend, then platform 7 cases, persistent ascend 4 cases. On CT of 15 cases, showed osteolytic bony destruction in 13 cases.Conclusion: MRI can demonstrate the invaded extent of the lesions clearly, and can provide more comprehensive information in diagnosis and therapy of adenoid cystic carcinoma of the head and neck.
