Abstract:
Objective To investigate the CT imaging features of basal cell adenoma in the parotid gland and thus to improve the preoperative diagnostic accuracy.Methods The clinical materials and image findings of 8 cases with parotid basal cell tumor,which were proved by pathology,were retrospectively studied.Results All 8 patients had solitary BCA lesion,which involved both the superficial and deep lobe(n =1) and located at the superficial lobe of parotid gland(n =7).All the 6 tumors were clear boundary and round shape without lobular appearance.The diameters of the max lesions ranged from 10.3-27.6 mm.CT scan showed that all lesions were solid nodules with uniform or uneven density.Cystic degeneration was displayed in 5 lesions,among them,cystic area was ≥90％ in 1 lesion.At enhanced scanning phase,most tumors showed a strong enhancement at the arterial phase and a pattern of persistent strong enhancement or slow decline at the venous phase.Conclusion The multi-slice CT imaging features of BCA in parotid gland are characteristic,which is helpful to make qualitative diagnosis in combination with clinical materials.
