The spectrum of findings is commensurate with chronic recurrent sialadenitis:
Sialodochitis with strictures, duct ectasia (sialectasia), sialocele formation (intraparenchymal cavities in parotid gland), and a large periductal diverticulum.
No calculus was seen. No fistula discernible. Also considering the lack of fever, there was little possibility of any one of these cavities being an abscess.
