Basal Cell Adenomas of the Parotid Gland:CT and MRI Features

Purpose To explore the CT,MR imaging and clinical features of basal cell adenoma of the parotid gland.Materials and Methods CT and MR imaging were performed in 37 patients with basal cell adenoma confirmed by pathology.The gender,age,clinical manifestation,localization,size,number,CT value,MR signal intensity and enhance pattern were observed in the parotid gland.Results Old women showed most basal cell adenoma of the parotid gland with manifestation of painless mass in parotid gland.The basal cell adenoma of the parotid gland was frequently observed in the superficial lobe of the parotid gland.37 lesions were commonly demonstrated that showed the round-like shape with clear margin and evident enhancement on CT and MR images.The diameters of the lesions ranged from 7-30 mm.The lesions were heterogeneous.21 patients(56.8%) suffered from cystic changes.Conclusion The basal cell adenoma of the parotid gland has certain clinical and imaging features,such as small in size,cystic changes,strong enhancement,which are helpful to the qualitative diagnosis of basal cell adenoma.
