Abstract: Objective To study the MR imaging features of soft tissue desmoid-Type fibromatosis in the head and neck.Methods 11 cases of soft tissue desmoid-type fibromatosis in the head and neck,which were confirmed by pathology,were analyzed retrospectively. The tumor location,morphological features,size,margins,intensity and contrast enhancement characteristics were assessed. Results In all 11 cases of desmoid-type fibromatosis,the lesions that were located in the perivertebral space( n = 5),carotid space( n = 4),submandibular space( n = 1) and masticator space( n = 1). the greatest dimension ranges from 2. 6 cm to 16. 1 cm,8 cases grew in the Muscular clearance with an elongated shape,and rim of surrounding fat( n = 6). 10 cases showed iso-intense or slight hypo-intense signal on T1-weighted image and high or slight high signal on T2-weighted image,with marked enhancement. Characteristic nonenhancing low signal intensity bands can be seen in the 10 cases. 1 case of lesions was low signal on both T1WI、T2WI and enhancement. Necrosis was not found in all lesions except one recurrence case. Edema was not seen in muscles. Conclusion Desmoid-type fibromatosis in the head and neck have some certain characteristics. Most cases can be accurately diagnosed preoperatively.
