CT imaging appearance and pathological features of basal cell adenoma in parotid gland / 局解手术学杂志

ABSTRACT

Objective To evaluate the clinical,pathological and imaging features of basal cell adenoma in the parotid. Methods The clinical,pathological and CT imaging data of 21 cases with parotid basal cell tumor confirmed by operation and pathology were retrospectively analyzed. Results All 21 patients(5 male,16 female ) had solitary BCA lesion,which located at the superficial lobe of parotid gland(n=17)and involved both the superficial and deep lobe(n=4). Twelve lesions were well-defined and cystic degeneration was displayed in 9 le-sions,3 lesions had punctate calcification at the edge of tumor. All lesions were significantly enhanced,the enhancement of BCA in the ve-nous phase was close to the arterial phase. Conclusion The CT features of BCA in parotid gland are characteristic,which is helpful to make qualitative diagnosis when in combination with clinical features.
